Description

A kind of rice snail symbiotic breeding method based on green manure

【Technical field】

The invention relates to the technical field of snail culture, in particular to a green manure-based rice snail symbiotic culture method.

【Background technique】

Snail is the common name of square ring snail, which is the whole of square ring snail or other animals of the same genus. Snails are rich in nutrition and delicate in meat quality, making them the best food on the dining table. Snail powder is a flavor snack in Liuzhou, Guangxi. With the development of bagged Liuzhou snail powder, the snail powder industry in Liuzhou, Guangxi has been continuously upgraded, and the demand for snail powder has continued to increase. Snails usually grow in rice fields, lakes, ponds, swamps and river ditches. Therefore, scientific three-dimensional planting in rice fields can not only meet the market demand for snails, but also ensure a good harvest of rice, which will help farmers increase their income and become rich.

Green manure is the essence of traditional agriculture in my country. As a source of biological fertilizer, it can improve soil fertility and improve the quality of agricultural products. The planting and utilization of green manure crops is conducive to reducing the application of chemical fertilizers, which is of great significance to ensuring the safety of agricultural products, protecting the ecological environment of farmland, and promoting the sustainable development of agriculture. At present, there are also many reports about the polyculture of snails in rice fields. The main function is to increase the value of commodities, so that both rice and snails can be harvested; however, snails are omnivorous molluscs, which may damage the roots of rice and cause the risk of rice production reduction. ; and the current nesting is just simple breeding, and there is no symbiotic system, that is, research on the integration of winter green manure, aquatic green manure, climbing green manure and rice snails.

In the invention, leguminous green manure is planted in slack fields in winter to fertilize soil fertility; aquatic green manure Hongping is used to raise snails in fertile fields; green manure in dry land is used to form hedgerows to prevent external interference and form an ecological planting and breeding system of rice and snails, which is beneficial to the production of health, Safe snails and rice; green manure of this application: winter green manure milkvetch has good nitrogen fixation ability as leguminous green manure, through no-tillage winter planting milkvetch in paddy field and stocking domestic geese in the early flowering stage of milkvetch, play a role in fertilization The role of soil fertility; aquatic green manure Hongping can fix nitrogen in the air, absorb micronutrient elements in water that cannot be used by rice, and has high protein content; stocking Hongping in rice fields can not only provide feed for snails, but also provide shade for them. A good environment for the growth of snails; at the same time, because Hongping is eaten by snails, it will not compete with rice for nutrients; plant economically valuable climbing leguminous green fat cat beans and Indian cowpea around the field ridge to form a hedge wall, and the rice snails will be shared The planting and breeding area is isolated from the surrounding area, thereby reducing the impact of spraying pesticides on the surrounding rice on snail culture. The cat beans and Indian cowpea planted at the same time can be used for food; the ratooning rice can be regrown by using rice piles after the first season of rice is harvested. Seedlings, long ears, and another season; the patented rice variety of the present invention uses ratooned rice, which can avoid re-planting in the second season after the rice is manually harvested in the first season of rice and snail co-cultivation, which reduces the impact on rice field snail cultivation, and realizes Maximization of benefits of rice and snail co-cropping. In addition to applying green manure, this application does not use chemical fertilizers in the field management process. The organic fertilizer used is fermented from cow dung, passion fruit peel, whey powder and bean curd residue. In the fertilizer, cow dung can improve soil fertility, passion fruit peel and In addition to improving fertility, bean curd residue can also be used as snail feed after fermentation. The whey powder contains higher whey protein, and the fat content of snail meat can be reduced after eating snails; the snail feed of this application is also self-made by the applicant. , composed of rice bran, wheat bran, papaya peel, pineapple seed powder and soybean powder, to ensure that the feed is loose and contains more trace elements, vitamins and protein, which can meet the growth needs of snails, increase the protein content of snail meat, and reduce fat content.

2. When cultivating the symbiotic system, this application adopts the method of "narrow row-wide row-narrow row" for transplanting and planting, which can effectively improve the yield and growth efficiency of rice, and at the same time, it will not affect the growth of snails. It can provide a cool growth environment and space for the growth of snails; the hedge wall support of the application adopts the mode of the grid frame being reversed, and the grid frame is detachable, which improves the portability and mobility.
