Example Embodiment

[0015] Example 1

[0016] A comprehensive planting and breeding technology integrating shrimp and rice, including the following steps:

[0017] (1) The paddy field is a unit of 50 mu. Before planting, the rice field excavated a ring-shaped ditch with a width of 2 to 3 meters and a depth of 1.5 to 2 meters. The soil excavated from the ring ditch was used to build a ridge, and the ridge was 0.6 to 0.8 meters above the field surface. The top surface is 3 meters wide, anti-escape nets are set on the ridge, and solar insect trap lights are set on the annular trench;

[0018] (2) Drop broodstock or shrimp larvae into the annular groove;

[0019] (3) Crayfish are caught in ground cages before transplanting mid-season rice from April to June each year, and all the adult shrimps of more than 30 grams are caught and marketed. The small shrimps that do not meet the market specifications are left in the rice fields. After the fishing is completed, small shrimps should be restocked. By August, be...

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...
