First, the middle and lower leaves turn yellow: eggplant plants are mainly middle and lower leaves. At first glance, the leaves have yellow spots and gradually develop into yellow leaves, but the veins are mainly yellow and the veins are still green. With the development of the disease, the leaves gradually become brittle, hard and brittle, and in severe cases, they will age and fall off, thus affecting the normal growth of the whole plant and leading to premature aging of the plant and eggplant fruit. The law of incidence is that it occurs in the middle and lower leaves and develops gradually from bottom to top, especially in the front of greenhouse and weak plants. Both big red fruit and pink fruit eggplant occurred, but pink fruit eggplant was the most serious, especially when the fruit began to swell from the third shed to the fourth shed. Symptom analysis: this is a symptom of magnesium deficiency in eggplant, a physiological disease, which is easily regarded as a bacterial disease. However, in this case, there is no shortage of magnesium in the soil, but the roots of plants have poor absorption of nutrients or low utilization rate of nutrients, which leads to this situation. In addition, this situation is also related to multiple cropping and improper fertilization, such as burning roots with immature organic fertilizer, soil hardening caused by long-term continuous application or excessive application of chemical fertilizer, poor root growth and uncoordinated nutrition caused by high salt ion concentration in soil. The main reason is the abnormal climate this year. Mainly due to the high temperature after eggplant planting, the root environment of eggplant is poor and the root growth is poor, which affects the normal absorption of nutrients by eggplant roots. Due to the lack of sufficient light for a long time, the crops have heart-shaped leaves (tops). ...

Spraying natural brassinolide and humic acid active liquid fertilizer plus potassium dihydrogen phosphate plus triacontanol, or compound sodium nitrophenolate plus amino acid active liquid fertilizer plus Xingpeng phosphorus and potassium Kalidaguang fertilizer 1 number on the leaves, twice a day 1 time, to accelerate the recovery of normal growth.
What preventive measures does hepatitis B have?
The first is the screening of immunization scope and vaccination targets. Immunization scope: active officers and civilian cadres of the whole army, cadets of military schools enrolled in 2008, cadets of military schools, noncommissioned officers and soldiers of the whole army. Screening of inoculation objects: those with negative detection of hepatitis B surface antigen antibody are inoculation objects; People with a past history of hepatitis B, patients with hepatitis B or those with positive results of hepatitis B surface antigen antibody are not vaccinated.
What preventive measures does gastric cancer have?
The curative effect of gastric cancer depends on whether it can be diagnosed early. If it can be found early, radical surgery before tumor metastasis will have better curative effect, especially when the cancer tissue has not invaded the muscularis and serosa, and the five-year survival rate is the highest.
The following measures are helpful to the prevention, early detection and early treatment of gastric cancer.
(1) Diet: Pay attention to food hygiene, eat less smoked, pickled and fried foods, and quit smoking and drinking; Eat more foods rich in vitamin E, such as fresh fruits and vegetables. Coarse grains are the staple food, meat should be eaten less, and the diet should be reasonable to prevent body fluids from being acidic. The intake of diet should be "two acids and eight alkalis", so that body fluids are weakly alkaline; Change bad eating habits: avoid overeating and three meals are uncertain; Eat too fast, too hot or too hard. Advocate the consumption of garlic and green tea. Food should be properly processed and cooked.
(2) Chronic atrophic gastritis, especially intestinal metaplasia and atypical hyperplasia, gastric ulcer, pernicious anemia and gastric polyp. , should actively treat and regularly follow up gastroscopy, timely detection of cancer and treatment.
(3) Bad habits: Smoking, drinking and other bad habits should be changed.
(4) Psychological factors: Nowadays, people have too much pressure in their daily lives. When this pressure is too great to be released, it will do harm to the body and increase the incidence of gastric cancer.
(4) Other precautions:
A. Do a good job in mildew prevention and pest control of grain, and protect drinking water hygiene.
B. actively treat precancerous lesions. Patients with chronic stomach diseases should be treated in time and observed regularly.
C. actively protect the environment and reduce environmental pollution.
D. Conduct general survey and treatment of gastric cancer and precancerous lesions in high-risk areas and high-risk populations.
In recent years, nutrition experts have found that eating the following foods regularly can reduce the incidence of gastric cancer.
1. Garlic is recognized as an anticancer food with obvious anticancer effect. Epidemiological investigation shows that people who eat raw garlic,
The incidence of gastric cancer is very low, because garlic can significantly reduce the content of nitrite in the stomach and reduce the possibility of ammonia nitrite synthesis, thus playing an anti-cancer role.
2. Onions Eating onions can reduce the content of nitrite in the stomach. Importantly, onion contains a substance called quercetin, which is a natural anticancer substance. Studies show that people who often eat onions,
The incidence of gastric cancer is 25% less than that of people who eat little or no onions, and the mortality of gastric cancer is 30% lower.
Step 3: mushrooms
This kind of food includes mushrooms, shiitake mushrooms, Flammulina velutipes and auricularia auricula. Scientists have found that many mushrooms in food contain anticancer substances, which can prevent cancer. For example, the polysaccharide contained in mushrooms has a very high anti-cancer rate. Auricularia auricula and polysaccharide contained in Auricularia auricula are also effective anticancer substances. The crude fiber and calcium rich in mushroom foods can prevent cancer and improve human immunity.
Molybdenum containing more trace elements can block the synthesis of carcinogen ammonium nitrite and play an anti-cancer role. It is reported that cauliflower also contains an enzyme called small sulfide, which can stimulate cell activity and prevent the formation of cancer cells. Eating cauliflower has a certain effect on preventing esophageal cancer and gastric cancer.

What are the preventive measures for disaster prevention?
By the end of this century, there have been more than 1 10 cities with a global population of more than 2 million, 40% of which are located within 200 kilometers of the boundary of tectonic plates or close to areas where destructive earthquakes have occurred in the past. There were 28 destructive earthquakes in about 44 big cities. From the San Francisco earthquake of 1906 to 1908. The death toll reached more than 500,000, and the property loss was about 375 billion dollars, which affected the economic output value (shutdown, foreign trade, etc.). ) 6543.8+80 million dollars. In addition, according to the statistics of the United Nations population report, there are 3 billion residents in large, medium and small cities (80% of which are cities in developing countries) living in earthquake risk areas. It is estimated that by 2035, the population in the earthquake risk area will increase by 1 times. This situation will only continue to increase, so we should do a good job in disaster prevention and mitigation. We should actively and effectively plan and implement disaster prevention and mitigation. How can disaster prevention and mitigation be carried out most effectively? More than 25 earthquake-prone countries have taken various measures to resist, prevent and rescue, which has provided us with rich and valuable experience. Some metropolises in developed countries (such as San Francisco and Los Angeles on the San Andreas fault in California, Japan's Tokyo earthquake circle and Hanshin earthquake belt) have formed cooperation between earthquake-resistant and disaster-prevention personnel and urban planners. Under the guidance of the government, joint measures have been taken to reduce casualties, property losses and social and economic impacts caused by future earthquakes, and certain practical results have been achieved. It is estimated that the earthquake of magnitude 19941October 7+0 in Los Angeles reduced the disaster losses by 50%. 65438+1On September 30th, 1995, the Mexico City earthquake with magnitude 7 reduced the disaster losses by 60%. The experience of many earthquake-stricken countries can be used for reference. While implementing disaster reduction measures, we must maintain social and economic sustainable development. Countries have different practices, such as: Japan: improving the seismic efficiency of buildings, earthquake drills, rapid communication and transportation, and effective use of underground space; Mexico: alternate urban communication system and use of underground space; United States: improving urban environment (land use, active fault investigation, etc. ), improve the architectural style of buildings, improve the seismic effect, strengthen the early detection system of earthquakes, respond to rescue quickly, and ensure the transportation system, so that the occurrence of earthquakes becomes a part of daily life. Are you ready next time? " In addition, earthquake-prone countries must have earthquake early warning systems; Develop intelligent buildings, install strong earthquake instruments, self-rescue devices and self-opening and self-closing devices (earthquake transmission switches, spherical earthquake-proof houses, automatic sliding control of tall buildings, computer security); The rapid response of individuals, volunteer teams, communities, the military and the government; Promote high, medium and low-grade disaster relief tools and facilities; Visit the earthquake site (prepare the site investigation-the format of socio-economic report); Development of building seismic detection platform: establishing community joint earthquake prevention training course; Conduct small-scale earthquake drills and install alarms; Use GPS, GIS, VCD, car TV system for disaster prevention and relief; Shock prevention of high-tech equipment; Impact resistance of computer system; Earthquake prevention of lifeline system, including residential and public facilities; Distribute earthquake preparedness manuals; Individuals and companies participate in purchasing earthquake insurance; Construction sites should be earthquake-resistant, old houses should be reinforced, earthquake alarms should be selected, and self-rescue, self-protection and escape devices should be purchased; Group measurement and prevention; Compiling earthquake-resistant and disaster-prevention plans and preparation plans for cities, communities, companies, factories, families and individuals; Popularize teaching materials of earthquake theory and application; Atlas for disaster prevention and mitigation; Handbook of earthquake prevention; Volunteer organization for earthquake relief; Earthquake Charity Relief (Red Cross Disaster Relief Statistical Database); Experience and lessons of military emergency response. How to do a good job in disaster prevention and mitigation? According to statistics, from 1960 to 1997, the types of major natural disasters have increased fourfold, and now there are 14 kinds. In the same period, the economic loss increased by 6 times and the insurance loss increased by 14 times. This trend shows that the efficiency of disaster reduction strategies and plans is lower than expected. There are more and more cities, more and more people, high-value facilities are concentrated, and people's prevention and rescue capabilities (knowledge, technology, investment, etc.). ) is weakening. In this case, our strategy should be expressed as attaching importance to earthquake safety as to national security. Enhance the ability of disaster reduction. From the disaster prevention and mitigation actions of various countries, it can be seen that international cooperation and overall planning between the government and relevant departments are essential. The government can formulate disaster reduction measures from top to bottom, including: establishing earthquake prediction and early warning system; Establish a disaster assessment system; Establish emergency rescue system and post-earthquake recovery and reconstruction system, and combine research, development and practical application well to achieve disaster reduction effect. The government should also tell the public and decision-making departments what to do in earthquake prevention and disaster reduction, including: learning from the experience provided by disasters; Buy earthquake disaster insurance and protect yourself by law; Popularize publicity and education and provide all kinds of anti-resistance brochures; Improve the dissemination methods and utilization of various seismic information; Increase the available technical means of prevention and rescue; Publicly admit the mistakes of human beings in the practice of prevention and rescue, and increase the awareness and knowledge of earthquake safety; Do a good job in interdisciplinary research and application of disaster prevention and rescue, sum up the above government practices, and summarize the operational guidelines of disaster prevention and mitigation management, which can be divided into: a large number of talents, funds and materials; Effective information dissemination and transportation guarantee; Practical urban earthquake prevention and disaster reduction planning; Effective supervision, inspection and improvement. The final disaster prevention plan should have the following characteristics: 1. Recognize and acknowledge the existence of disasters from the personal aspect (1); (2) Using existing knowledge to actively maintain stability and order; (3) The overall concept of disasters combining science and technology, politics, society, economy, law, psychology, military and international. Second, from the relevant decision-making departments (1), theory and application, new concepts and new technologies are combined rather than separated; (2) Coordinate and prepare emergency resources, make independent decisions and guarantee independently; (3) Anticipate possible problems and difficulties, prepare solutions, and speed up rapid response in case of emergency. (3) Organize and coordinate with the government (1): government, unit, community, family and individual; (2) Preparation, exertion, maintenance and transformation of urban functions; (3) actual demand and supply.
What are the preventive measures for atrial fibrillation?
Preventive measures of atrial fibrillation: adjusting mentality and living habits and controlling other diseases. The prevention of atrial fibrillation is first of all the adjustment of mentality. Many people have high blood pressure and heart disease. The important reason is that they have a bad mentality when dealing with the pressure of life or work, which in turn increases the pressure and easily leads to hypertension, diabetes, coronary heart disease and so on. , are related. People who are stressed and in a bad mood often have poor rest and sleep, and their immune system is vulnerable to attack. Therefore, the primary factor to prevent atrial fibrillation is to adjust the mentality. Second, try to control blood pressure. Blood pressure is greatly influenced by mood and lifestyle. It is not considered hypertension to find that blood pressure rises once or twice. You should rest for at least half an hour before taking your blood pressure. If it is high, let's see if the pressure of life is great recently. Or catch a cold? Or is it "white coat hypertension" caused by nervous medical treatment? Excluding these factors, you can take several tests at another time, and we can only diagnose hypertension after several consecutive high levels. If you have high blood pressure, you need to change your lifestyle first, then you need proper exercise, and thirdly, if you need to take antihypertensive drugs, you must take them regularly for a long time. In addition, the prevention of atrial fibrillation also needs the prevention and control of some other diseases. For example, the prevention of diabetes is mainly to control diet. Some factors are difficult to control, but it is possible to control diet, that is, to reduce the intake of high-fat and high-sugar foods.
What are the preventive measures for hemorrhoids?
Hello, the first thing to prevent hemorrhoids is to get rid of bad habits. When you go to the toilet, you should read newspapers and sit on the toilet for ten minutes or even half an hour. Many patients with hemorrhoids have this habit. In fact, developing good defecation habits is the first step to stay away from hemorrhoids. Whenever there is obvious defecation, you should go to the toilet immediately and concentrate on defecation. Don't do it at once. Because the defecation time is prolonged, it will aggravate the congestion of anal canal and rectum and expand the congestion of venous plexus. After a long time, it is easy to cause hemorrhoids. Many constipation patients often use too much force when defecating, which will also cause anal canal and rectal congestion. Some elderly people often have difficulty defecating because of insufficient middle qi and loose anal muscles. In this regard, experts suggest that you might as well try to press the left lower abdomen by hand to make the feces show downward, or press it upward in front of the coccyx, that is, behind the anus, to help the feces discharge smoothly. The key to prevent constipation is to ensure adequate drinking water every day. Drinking a glass of light salt water on an empty stomach after getting up has the effect of relaxing bowels and softening hardness, which can not only increase gastrointestinal peristalsis, but also regulate autonomic nervous function, which is conducive to smooth defecation. Excessive intake of high-protein, high-calorie food, while eating only a little vegetables and fruits, can also cause hemorrhoids. Experts point out that we should eat more fresh vegetables and fruits in our daily life, especially those containing cellulose, such as green vegetables, spinach, celery, leeks and lettuce. Eating less spicy food is a necessary condition to stay away from hemorrhoids. Because irritating foods such as pepper, strong tea, coffee and mustard will not only aggravate the regional congestion and anal sinusitis of anus, but also weaken the resistance of blood vessel wall. I hope my answer is helpful to you.
