Scientific paddy field crayfish breeding method

Abstract

The invention discloses a scientific paddy field crayfish breeding method, and belongs to the technical field of crayfish breeding. The scientific paddy field crayfish breeding method comprises the following steps of S1, planning of a paddy field, wherein circular ditches are dug, the opening of each ditch is 3.5-4.5 m, the depth of each ditch is 0.9-1.1 m, the slope ratio is 1.0:2, ridges are firm, the width of the top of each ridge is 2.2-2.4 m, each ridge is 0.6-0.7 m higher than the field face, iron fences are arranged at drainage ports, crayfish anti-escape nets are arranged between the field face and the circular ditches, and planting devices are arranged in the field face and the circular ditches; S2, improvement of the water quality, wherein from the beginning of February, new water begins to be injected, and the water injection depth is 8-9 cm; S3, putting of crayfishes, wherein the young crayfishes which are large in size and high in activity degree and have a strong crawlingcapacity are selected; S4, manual food putting, wherein food is put regularly every day; S5, paddy field fertilization, wherein at the end of April, base fertilizer is applied into a ploughing layerat a time; S6, rice transplanting, wherein at the end of May, rice is transplanted to the paddy field; S7, pesticide application to the rice. The breeding method is scientific and reasonable, and theyield of the crayfishes and rice is effectively increased.

Description

technical field [0001] The invention relates to the technical field of lobster culture, and more specifically, relates to a scientific method for raising shrimp in paddy fields. Background technique [0002] The shrimp-rice co-cropping comprehensive planting mode adopted by farmers mainly has the characteristics of less investment, low risk, short cycle, quick results, good benefits, and easy operation. Taking shrimp-rice co-production as an example, the yield of high-quality rice per mu (organic rice quality ) about 500kg, and the income of shrimp increases. Generally, the output per mu of crayfish is 75-100kg, and the output of cabbage sprouts is more than 500 kg. above. [0003] In recent years, the demand for crayfish in the domestic market has been increasing day by day, and the supply is in short supply. Especially, the domestic consumption is more popular. The price of crayfish has been rising rapidly, and it has become the variety with the largest increase in aquati...
