Problems solved by technology

[0002] Conventional rice field farming of crayfish is an aquaculture technology that has emerged in the past 10 years. Generally, it is necessary to dig fish ditches and fish dams in the rice fields, and widen and enlarge the pond ridges of the rice fields, which have a greater impact on the planting layer of the basic farmland. At the same time, it also reduces the rice planting area of ​​the rice field, which poses a threat to the safety of the basic farmland area.

Embodiment 1

[0096] The present embodiment provides a method for cultivating crayfish in a paddy field, and its overall process is as follows:

[0097] Every year from mid-March to early April, juvenile shrimps are placed in the transformed idle rice fields and cultured; from mid-May to the end of June, adult shrimps are harvested; from late June to early July, the fields are pruned, transplanted and dried; from October to November The late rice is harvested every month; the harvested rice fields are left idle until the next stocking of juvenile shrimp.

[0098] Specifically, it includes field engineering, crayfish paddy field ecological breeding and rice planting.

[0099] (1) Field works are as follows:

[0100] 1.1 Heightening and strengthening field ridges 4

[0101] Dig up the 1.30m soil of the cultivation layer, take the soil 0.15-0.2m below the cultivation layer 1, widen and heighten the ridge 4, the ridge height is 1.0m, the bottom width is 1.3m, the surface width is 0.8m, and th...

Abstract

The invention discloses a method for breeding crayfish in a ditch-free rice field, and belongs to the technical field of crayfish breeding, and the method comprises the following steps: putting juvenile crayfish in a crayfish breeding system and breeding the juvenile crayfish from the middle ten days of March to the first ten days of April every year; harvesting adult shrimps from the middle of May to the end of June; preparing the field from late June to early July, transplanting rice seedlings, and drying the field; late rice is harvested from October to November; the harvested rice field is idle until the juvenile shrimps are put in the next time; wherein the crayfish breeding system comprises a reconstructed unfurrowed rice field, and the reconstruction of the rice field comprises the steps that soil below a plough layer of an idle rice field to be reconstructed is taken to widen and heighten ridges, and then the soil of the plough layer is backfilled, leveled and reclaimed; in the process of transforming the idle rice field, no ditch or puddle is dug. According to the method, the engineering amount of field infrastructure construction is small, one-season crayfish breeding and one-season rice planting are carried out on the premise that the basic farmland rice planting area is not occupied, and the rice field breeding income is increased.

Description

technical field [0001] The invention relates to the technical field of crayfish cultivation, in particular to a method for cultivating crayfish in a ditchless paddy field. Background technique [0002] Conventional rice field farming of crayfish is an aquaculture technology that has emerged in the past 10 years. Generally, it is necessary to dig fish ditches and fish dams in the rice fields, and widen and enlarge the pond ridges of the rice fields, which have a greater impact on the planting layer of the basic farmland. At the same time, the rice planting area of ​​the paddy fields has been reduced, posing a threat to the safety of the basic farmland area. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] The object of the present invention is to provide a kind of method for cultivating crayfish in paddy field, to overcome above-mentioned technical problem. [0005] This application can be implemented like this: [0006] Thi...
