Embodiment 1

[0020] The method for ecological cultivation of red-clawed crayfish and stone snail rice field comprises the following steps:

[0021] (1) Select suitable paddy fields

[0022] The paddy field ridge is heightened and reinforced to more than 50cm. The water inlet is installed with a mesh bag made of 40-mesh silk screen with a length of 2.0-2.5m and a diameter of 25-30cm. 30cm land-based anti-escape membrane;

[0023] (2) Plant rice

[0024] Rice is planted according to the season, and 400-500kg of fermented and matured organic fertilizer is applied per mu of rice field before planting; when rice is planted, the 1.0-1.2m wide range around the field is not planted, and then every 1.0-1.2m wide range of rice is planted at intervals of 1.0 The range of -1.2m wide is not planted, and the row spacing of rice plants is 18cm×15cm.

[0025] (3) Stocking shrimp and snail seedlings

[0026] After rice root tillering is over, add water into the field until the water depth is 15-20cm, a...

Abstract

The invention discloses an ecological breeding method for cherax quadricarinatus and stone snails in a rice field. The method is composed of the steps of selection of a suitable rice field, timely planting of rice, stocking of young cherax quadricarinatus and young stone snails, feed feeding, daily management and harvest and overcomes the defect that comprehensive planting and breeding benefits ofthe rice field are low. Conditions are provided for simultaneous polyculture of the cherax quadricarinatus and the stone snails in the same rice planting field, the comprehensive planting and breeding potential of the rice field can be fully excavated, the process is simple and practical, operation is easy to understand, and the comprehensive planting and breeding benefits of the rice field can be improved by 30% or above.

Description

technical field [0001] The invention relates to the technical field of aquaculture, and relates to a method for ecologically cultivating red-clawed crayfish and stone snails in paddy fields. Background technique [0002] Crayfish and stone snails are both practical and effective measures to improve the efficiency of paddy farming. Before the present invention, the paddy field cultivation of red claw crayfish and stone snails is a single species of paddy field cultivation, the comprehensive cultivation potential of paddy fields has not been fully tapped, and the breeding benefits are relatively low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an ecological breeding method for red-clawed crayfish and stone snails in paddy fields, so as to solve the problem of relatively low benefit of comprehensive paddy cultivation. [0004] The technical solution for solving the above-mentioned technical problems is: a metho...
