Method for culturing field snails in rice field

Abstract

The invention discloses a method for culturing field snails in a rice field. The method includes the steps that the rice field is treated, wherein after the rice field is drained, crop straw is scattered, soil is deeply turned, then, 5-8 kg of quick lime is used per mu for disinfection and pest removal, the disinfected rice field is injected with water, the water is drained after 3-5 days of standing, a layer of 2-3 cm manure is applied and turned into the soil, then, the rice field is aired for 4-8 solar days, a 20-30 ditch is dug in the rice field every 10-20 cm, and after water replacementis performed once, rice planting can be performed; 10-15 days after rice planting, the field snails are put into the rice field to be cultured. According to the method for culturing field snails in the rice field, the rice field ecosystem is fully utilized for virtuous cycle culture, the yield of rice is increased by 10%, and the yield of field snails is increased by 15%; besides, the culture costis reduced, the famers' income is increased, and the method has broad market application prospects.

Description

technical field [0001] The invention belongs to the technical field of paddy field cultivation, and in particular relates to a method for paddy field cultivation of snails. Background technique [0002] Field snails generally refer to molluscs of the family Snailidae, belonging to the phylum Gastropoda Probranchia Snailidae. Escargot is distributed in most parts of China. Escargot is an ovoviviparous animal with a unique reproductive mode. The embryonic development and snail development of the snail are all completed in the mother's body. From fertilized eggs to the generation of young snails, it takes about one year to conceive in the mother's body. Field snails lay eggs in batches, and start breeding from March to April every year. While producing young snails, the female and male parent snails mate and fertilize, and at the same time give birth to the young snails to be produced in the next year in the mother. A female snail produces about 100-150 young snails througho...

Problems solved by technology

Now snail culture is divided into culture pond culture and paddy field culture, and culture pond culture, because cost is too high, is unfavorable for large-scale popularization; And existing rice field culture makes the snail survival rate low, poor quality because of technical method processing.
