Embodiment Construction

[0016]

[0017] A method for cultivating crayfish in paddy fields, comprising the following steps:

[0018] Selection of paddy fields: choose contiguous paddy fields with an area of ​​80 mu, sufficient water sources, convenient irrigation, good water quality and no pollution;

[0019] Paddy field planning: Excavate multiple small ditches in the shape of "Tian" or "Jing" in the paddy field, the small ditches are 30-40cm wide and 10-20cm deep; large ditches are excavated inside the field ridge, and large ditches are also set outside the field ridge. The ditches, the inner and outer ditches are connected by water ditches, the ditches are 1.5m deep, 80cm deep, and the slope ratio is 1:2.5; the outer ditches are connected to multiple ponds with an area of ​​30㎡ and a depth of 1.5m. Anti-escape nets are installed around the pond, and anti-escape nets are installed at the inlet and outlet of rice fields, and the ridges need to be reinforced to prevent collapse;

Abstract

The invention relates to the aquaculture field, in particular to a method for farming crayfish in a rice field. The crayfish is farmed by utilizing the rice field, both rice and the crayfish can be benefited; the omnivorous characteristic of the crayfish is utilized, weeds and harmful insects are killed in the rice field, the usage amount of pesticide is lowered, and a lot of management cost is reduced. Meanwhile, the planted rice is small in pesticide residue and environmentally friendlier. The crayfish has a lot of edible plants and insects in the rice field, thrown feed is reduced and saved by utilizing rice field farming, and the production cost is reduced. The effect of remarkably increasing production is further achieved by using the method, the yield of the rice can be increased by 5%-10% per mu, and the yield of the crayfish can reach 400 kg per mu.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating crayfish in paddy fields. Background technique [0002] Because of its delicious taste, crayfish are deeply loved by consumers. However, most of the current farming is carried out in a single culture mode, which cannot rationally develop and utilize existing resources, resulting in waste of resources and poor economic benefits. Contents of the invention [0003] The purpose of the invention is to develop a production mode of intercropping and interplanting, rationally utilize resources, and achieve the maximization of benefits. [0004] In order to solve the problems referred to above, the technical scheme adopted by the present invention is: a kind of method for cultivating crayfish in paddy field, comprises the following steps: [0005] Selection of paddy fields: Choose contiguous paddy fields with an area of ​​50-100 mu, with sufficient water sources, con...
