Crayfish and rice integrated comprehensive planting and breeding technology

Abstract

The invention relates to a crayfish and rice integrated comprehensive planting and breeding technology which includes the following steps: (1) enabling 50mu of rice fields to serve as a unit, excavating an annular groove in the rice fields before planting and breeding are carried out, arranging a solar moth-killing lamp in the annular groove, and arranging an anti-escaping net on a ridge; (2) putting parent crayfishes or crayfish seeds in the annular groove; (3) fishing crayfishes with a ground cage before semilate rice is transplanted in April to June every year, fishing all adult crayfishes heavier than 30g to come into the market, leaving small crayfishes which cannot meet the in-the-market specifications in the rice fields, breeding is continuously carried out after semilate rice is transplanted, putting small crayfishes in a supplement mode after the large crayfishes are completely fished, leaving sufficient parent crayfishes in August before the semilate rice is harvested, fishing all the other crayfishes to come into the market, and then harvesting the semilate rice. Compared with a traditional crayfish and rice crop rotation mode, the crayfish and rice integrated comprehensive planting and breeding technology has the advantages that one-more-time crayfish harvesting is achieved, the crayfishes and the semilate rice are bred and planted in the same period, the crayfishes can wipe out weeds and injurious insects in the rice fields, the semilate rice can easily grow, pesticide applied to the rice fields is reduced, the planting cost is reduced, and the quality of the semilate rice is improved.

Description

[0001] technical field [0002] The invention relates to a planting and breeding technology, in particular to a comprehensive planting and breeding technology in which shrimp and rice are integrated. Background technique [0003] With the popularization of agricultural science and technology, more and more methods of planting have been recognized by people. Among them, "shrimp and rice rotation" is a scientific breeding technology. By cultivating lobsters in rice fields, the paddy fields can be fully utilized. However, "Shrimp-rice rotation" is often planted in autumn, and the spring catch is completed before the mid-season rice is transplanted, and the mid-season rice is no longer raised after transplanting, which makes the growth time of crayfish shorter, the individual size of crayfish is relatively small, and the output is low. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a comprehensive planting and breed...

[0003] With the popularization of agricultural science and technology, more and more methods of planting have been recognized by people. Among them, "shrimp and rice rotation" is a scientific breeding technology. By cultivating lobsters in rice fields, the paddy fields can be fully utilized. However, "Shrimp and rice rotation" is often planted in autumn, and the spring fishing is completed before the middle rice is transplanted, and the middle rice is no longer raised after transplanting, which makes the growth time of the crayfish shorter, the individual size of the crayfish is relatively small, and the output is low
