Problems solved by technology

However, the existing shrimp-rice continuous cropping method has a large gap between the rice planting period and the aquatic animal breeding period, which fails to effectively improve the utilization rate and overall efficiency of farmland. The short growth period leads to small size and poor plumpness of commercial shrimp. The seedlings are not guaranteed, resulting in unstable production and unsatisfactory economic benefits.

Embodiment 1

[0024] Embodiment 1 of the present invention provides a kind of method for rice and shrimp comprehensive cultivation, and it comprises the following steps:

[0025] Paddy field reconstruction: choose a 60-mu paddy field that is easy to care for, with open ground, flat terrain, shelter from the wind and sunshine, quiet environment, sufficient water source, good water quality, no drought and no waterlogging, smooth drainage and irrigation, fertilization at the bottom of the field without silting, and solid ridges without water leakage ; Excavate an annular deep ditch on the paddy field, and carry out sterilizing treatment to said annular deep ditch, to kill harmful organisms and pathogenic bacteria in said annular deep ditch, wherein, the area of ​​said annular deep ditch Accounting for about 10% of the total area of ​​the paddy field, the annular deep ditch has a width of about 4m, a depth of about 1.2m, and a slope of about 45 degrees; a paddy field planting area is formed in t...

Embodiment 2

[0033] Embodiment 2 of the present invention provides a kind of method for the integrated cultivation and cultivation of rice and shrimp. The cultivation method provided in this embodiment is basically the same as the cultivation method provided in Embodiment 1, the difference is that:

[0034] In the step of improving the paddy field, the selected paddy field is 50 mu, and the area of ​​the annular deep ditch accounts for about 12% of the total area of ​​the paddy field. The width of the annular deep ditch is about 4.3 m, and the depth is about 1.5 m. The slope is about 49 degrees;

[0035] In the step of rice cultivation, the distance between transplanting rice seedlings is 40 cm × 40 cm; in the step of raising crayfish, the ratio of male to female in broodstock is 3:1, and the stocking density of shrimp seedlings is about 7000 tails / mu;

[0036] In the step of establishing the ecosystem, the total coverage rate of Elodea, Erythria balsamicus and Hydrilla verticillium plan...

Embodiment 3

[0040] Embodiment 3 of the present invention provides a kind of method for the integrated cultivation of rice and shrimp. The cultivation method provided in this embodiment is basically the same as the cultivation method provided in Embodiment 2, except that:

[0041] In the step of improving the paddy field, the selected paddy field is 64 mu, and the area of ​​the annular deep ditch accounts for about 15% of the total area of ​​the paddy field. The width of the annular deep ditch is about 5 m, and the depth is about 1.4 m. The slope is about 47 degrees;

[0042] In the step of rice cultivation, the distance between transplanting rice seedlings is 45 cm × 45 cm; in the step of stocking crayfish, the stocking density of shrimp seedlings is about 8000 tails / mu;

[0043] In the step of establishing the ecosystem, the total coverage rate of the Elodea, Erythrophila and Hydrilla verticillium planted in the annular deep water ditch is about 60%, and live snails are put into the padd...

Abstract

The invention provides a rice and crayfish synthesized planting and breeding method. The method comprises the following steps of rice field modification, rice cropping, small crayfish stocking, ecological system building, daily management, product harvesting and the like. The synthesized planting and breeding method combines timed crayfish breeding, ecological system building, precise feeding of mixed feed, rice field water fertilizer synthesized management, pest control, compound microecologicsapplication and other technologies, achieves dual purposes in one field, effectively improves the farmland utilization rate and comprehensive efficiency, and improves the economic benefits.

Description

technical field [0001] The invention belongs to the technical field of mixed planting and breeding, and in particular relates to a method for comprehensive planting and breeding of rice and shrimp. Background technique [0002] In addition to the improvement of high-yield seeds and farming techniques, the stable and increased production of existing grain relies to a large extent on the use of a large amount of chemical fertilizers and pesticides. However, this modern agricultural production method based on chemical fertilizers and pesticides to obtain stable and high yields has not only ensured food security, but also caused some ecological and environmental problems, such as: increased agricultural non-point source pollution, soil erosion and degradation, reduction of natural enemies of pests and diseases, agricultural biological Decreased diversity and decreased quality and safety of agricultural products. Faced with the above problems, people have increasingly realized t...
