In the past, Eupolyphaga sinensis was captured as a source of medicinal materials. In recent years, due to the change of environment, Eupolyphaga sinensis has lost its natural breeding place, so it has been artificially raised in many parts of the country.
Artificial breeding of Eupolyphaga Seu Steleophaga is a sideline project with low cost and high economic benefit. Many farmers have begun to use their homes for artificial breeding.
Key points of breeding
1, feeding conditions. Eupolyphaga likes to live in dark, humid and humus-rich loose soil, and has strong adaptability. As long as you keep a certain temperature and humidity, you can raise it anywhere.
2. Three-dimensional factory feeding. The equipment for raising Eupolyphaga is relatively simple, and plastic pots can be cultivated on a small scale. In order to cultivate Eupolyphaga on a large scale, a three-dimensional multi-layer feeding platform can be adopted.
The specific method is to build bricks against the wall in the house, and the height of each floor is controlled at about 30-38cm. It is best to use cement board for the floor, and each wall can be built with 5-7 layers of feeding tables. Practice has proved that this kind of feeding platform can make the indoor temperature 6- 10℃ higher than that of the flat pool, and the growth and development of soil elements are obviously accelerated. It only takes about 7 months to complete a generation, and the annual output is significantly improved.
3. Feed distribution. Eupolyphaga is an omnivorous insect. As long as it is a pig, it can eat anything, such as wheat bran, rice bran, cakes, green fodder, potatoes, vegetable leaves and bones. And feed it once a night. Eupolyphaga is the most gluttonous earthworm and can be used for breeding.
4. Scientific management. Scientific management is the key to the success of artificially raising Eupolyphaga. Mites are common parasites in Eupolyphaga feeding. The control method can be 1: 400 times diluted 20% dermatophagoides farinae powder mixed into the feeding soil. You can also remove mites by changing the feeding soil in time or using fried dough sticks, bones and pumpkin flowers as bait.
Eupolyphaga introduction
The advanced method of Eupolyphaga cultivation is three-dimensional constant temperature cultivation, which has high economic benefits, but it is aimed at large-scale farmers who are being cultivated.
For customers who have just started to prepare for Eupolyphaga cultivation, Eupolyphaga cultivation can't be discussed when it is not yet or very young, so it is worth noting when introducing it.
Eupolyphaga in the south grows in the natural environment for much longer than that in the north, so the introduction from south to north is not regional, just as plants can grow well when transplanted from the natural environment to the greenhouse.
When Eupolyphaga was introduced, the price and quality in the market were quite different. Some early breeders actively introduce Eupolyphaga seeds when they see the low price, thinking that this can not only cultivate Eupolyphaga but also save a sum of money, but pay attention to the quality of seeds.
Some farmers think that seeds with high prices and high recycling prices are good seeds, but we should pay attention to market principles. It is more accurate to inquire about the market price of Eupolyphaga in the medicinal materials market. Why are some recycling prices much higher than the market? This problem deserves the attention of beginners.
Feeding and management
Larval feeding management
Larvae began to eat 2 days after hatching. At this time, you can feed some wheat bran, melons and fruits, pumpkin flowers, small vegetables and shredded pumpkin, and add some nutritious foods such as bean flour, eggs and milk in the larval stage. As long as the feed is sprinkled on the surface of the feeding pond, the temperature is kept at 25 ~ 43℃.
Feeding and management of worms in China
The management of Chinese worms is relatively extensive, and there is no special requirement for feed, as long as you can eat enough.
Feeding and management of ovipositor
Egg-laying insects require the soil to be thickened 12 ~ 15 cm, and the ratio of green feed to concentrated feed should be 50%. It would be better to add a little bean powder or animal meat scraps to increase the nutrition of Eupolyphaga Seu Steleophaga. Feeding situation as long as there is not much feed left on the surface of Tuyuantang the next morning.
The temperature in the feeding pond can be kept at about 25℃ and the humidity is 60% ~ 70%. If the humidity is not enough, it can be humidified with a sprayer, without pesticide pollution, and the number of times needed is not much.
Three-dimensional high-density culture technology
1, feeding density and feeding soil thickness
The feeding soil thickness of Eupolyphaga sinensis 1-4 years old is generally 2-3 cm. With the growth of Eupolyphaga sinensis, the feeding density is increasing, and the thickness of feeding soil is gradually increasing.
Relationship between feeding density and humidity. If the density is too small, the activity of Eupolyphaga sinensis is too small, which will easily lead to the hardening of the feeding soil, uneven dryness and wetness, affecting its growth (because the water needed for the growth of Eupolyphaga sinensis depends on its body surface), and those who are seriously short of water will die.
When the feeding density reaches a certain level, the humidity of the feeding soil can be kept constant through the activities of Eupolyphaga sinensis, and a generation cycle can be completed in 6 months.
Feeding density should not be too high. Generally, the bottom of the pond is patted by hand, and the highest density is the wave-like peristalsis on the surface of the pond.
2. Feeding density and temperature
The breeding density is 0.35 kg/m2 (the emergence rate of insects is 70%-80%). When it grows to 4-5 years old, the temperature of the feeding room can be controlled by using the temperature of the insect body (the feeding room can be built according to the three-dimensional constant temperature method). Generally, 0℃ is an unheated hibernation period. 0℃-25℃ is not suitable for growth; 25℃-32℃ is the optimum growth period; The death period is above 40℃.
3. Feeding density and economic benefits
High-density feeding can save energy and cost, and increase production with the same investment.
4. Feeding density and feeding management
In the process of feeding, it is appropriate to master the feeding density, which is conducive to mastering the feeding quantity and will not cause the phenomenon of leftovers and lack of food. At the same time, it is beneficial to keep the humidity constant and make the Eupolyphaga sinensis molt normally.
control of insect
bug
Scrape the soil on the surface of the culture pond, screen it out with a sieve (window screen) and throw it away. If there is a little soil element in the sieve, mix it with lime powder and put it in the soil element pool once a day. After 5 days, there were basically no mites.
Disinfect. Clean the ground, take trichlorfon tablets for animals and dissolve them in 2000 times of clear water, and then spray the ground with liquid medicine for disinfection.
Taking advantage of the habit of Eupolyphaga Seu Steleophaga lying in the daytime and coming out at night, put fried dough sticks and fried white sugar on the feeding board during the day to lure the mites to eat, and take them out for treatment two hours later to kill the mites. Repeated several times can reduce the harm of mites. If mites have multiplied and caused harm in the feeding pond, only the feeding soil can be changed.
natural enemy
Eupolyphaga has many natural enemies, such as mice, ants, spiders, chickens, ducks and cats, etc ... The feeding pond should be sealed to prevent natural enemies from entering. Spider control can be accomplished by vacuuming once a week.
Use of pesticides
Be careful when feeding Eupolyphaga Seu Steleophaga to prevent pesticide from polluting the feed. Mosquito-repellent incense and pesticides are also deadly to Eupolyphaga sinensis, so their use is strictly prohibited.
Soil element harvesting
Three months after Eupolyphaga sinensis laid eggs, the peak of spawning has passed, and a large number of deaths appeared on the inner surface of the breeding pool. When the weather is clear, harvest a large amount at one time, fish the Eupolyphaga from the pond with a sieve with 1 cm eye, screen out the soil, put the screened Eupolyphaga in boiling water to die, rinse it clean and dry it in the sun.
If it is rainy, the dryness of soil elements should be tested by drying method. You need to squeeze Eupolyphaga's abdomen by hand. There is no soft substance in the abdomen of dry Eupolyphaga. The drying rate of Eupolyphaga Seu Steleophaga is 43%, and the dried Eupolyphaga Seu Steleophaga can be sold. Quality requirements, dry, no impurities, no mildew.
