Embodiment 1

[0028] The method for freshwater breeding and edible weed rice hairy crabs comprises the following steps:

[0029] (a) Choose a large breeding pond, remove sundries and harmful substances in the breeding pond, sterilize with a mixture of tea seed powder and quicklime, and divide the breeding pond into three pieces; two of them are filled with river water, and the water depth is at 1.5 The remaining area is filled with soil to a height higher than the breeding pond, which is the planting area; in the breeding area facing the breeding area, there is a gradient for selecting high-quality hairy crabs to climb to the planting area , there are partitions with a height of 35cm around the planting area, and oxygen supply devices are provided at the bottom of the pond in the breeding area and the mature area;

[0030] (b) Plant rice in the planting area, and use compound fertilizers such as amino acid fertilizer, biological bacterial fertilizer, B-type peptide fertilizer and EM bacteria ...

Abstract

The invention discloses a method for culturing hairy crabs eating weedy rice in freshwater, and relates to the technical field of agriculture. The method comprises the steps that the hairy crabs are cultured by separating a culturing zone, a planting zone and a maturation zone step by step, juvenile crabs mainly taking the weedy rice as main food are cultured, and therefore the hairy crabs can massively eat the weedy rice in rice after entering the planting zone; the one-way channel gradient for selecting the high-quality hairy crabs to enter the planting zone is set in the culturing zone to select the high-quality hairy crabs. By implementing the technical scheme, the problem that work for selecting the high-quality juvenile crabs in the culturing zone is complex is solved, the problem that the survival rate of the hairy crabs is low due to the fact that the situation that the weak serves as a prey to the strong occurs on the hairy crabs in the planting zone is avoided, the weedy rice in the rice can be removed, and therefore an economic benefit and ecological benefit win-win effect is achieved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for cultivating and eating weedy rice hairy crabs in fresh water. Background technique [0002] Hairy crab is a well-known delicacy, which is loved by most people. Crab contains more vitamin A, which is helpful for skin keratinization; it can also supplement calcium for children's rickets and osteoporosis of the elderly. qualitative role. Hairy crabs were originally cultured naturally, with limited output, which could not meet the market demand. Facing the ever-expanding market demand, the breeding sites, breeding mode and breeding quality have all been challenged to a certain extent. The fresh water area of ​​Guizhou itself is also a rice planting base. With the promotion of simplified rice cultivation techniques, the weedy rice in rice will spread further, and the weedy rice is very similar to cultivated rice. The choice of herbicides during the period However,...
