No matter the vegetable planting season, it will suffer from pests and diseases. This will lead to serious economic losses and growth. Therefore, for the growth of eggplant, we should actively take measures to prevent and control pests and diseases, rationally use agricultural technology and modern prevention and control technology, and formulate corresponding prevention and control policies, but we should pay attention to the quantity and concentration of pesticides used in the prevention and control process to effectively control eggplant pests. Eggplant planting techniques and pest prevention keep pests away from healthy eggplants.
First of all, the outline of eggplant
Eggplant concept. Eggplants are mostly purple in appearance, with burrs, relatively large leaves and grooves of about1-1.8cm.. Roots can be used as medicine, but it is worth noting that eggplant can cause food poisoning. Eggplant likes to grow at high temperature, and its metabolism is gradually disordered at low temperature. Eggplant grows under high conditions, and the highest efficiency can only be achieved under suitable lighting conditions. In the early stage, eggplant has little water, so we should pay attention to proper watering when planting eggplant. When the growth is most short of water, the soil must be always wet, but the humidity should be moderate to avoid eggplant wet disease.
2. Eggplant seedling raising technology
(1) seed therapy. Before planting eggplant, the seeds are daunting, about 7 hours, then soaked in warm water.
(2) Germination technology. Wash away the mucus on the outer surface, then use gauze to adapt to the temperature, and rinse for seven hours as a cycle. When the seeds change gradually, you can sow.
(3) Management of seedling cultivation. In order to eliminate the harm caused by bacteria and microorganisms in the soil, non-porous technology can be used to raise seedlings, that is, mixing grass ash and vermiculite to form initial seedlings, and then expanding the seedlings into the culture medium again and placing them at a suitable temperature.
(4) Planting eggplant seedlings. Implant the cultivated seedlings into the soil. At this time, eggplant seedlings have certain resistance, but we should pay attention to the seedling spacing, keep each plant about 30 cm, and wait for water regularly.
(5) Seedling management during planting. To check the surface temperature, it should not be lower than 15℃, and the ventilation should always be under the condition of too high temperature, which can not grow normally. Reduce the ventilation on cloudy days because it is very small. Weather in which photosynthesis is very low and only sunlight can be released correctly. And pay attention to fertilization and fertilization amount.
