Abstract

The invention relates to the technical field of crop planting and aquaculture, in particular to a breeding method of crawfish polyculture in a lotus root field. The method comprises the four steps of farmland work of lotus root field construction, selection of cultivation and breeding time, cultivation management of lotus roots and breeding management of crawfish. According to the breeding method, water body space of a lotus root field piece is sufficiently used for culturing crawfish, firstly, aquatic plants and biological baits in the lotus root field can be used as natural feed of the crawfish, the biological weeding effect of the lotus root field is achieved, and the use ratio of the lotus root field is improved; secondly, excrement of the crawfish can further provide organic fertilizer for the lotus root field, virtuous cycle is achieved, and therefore the method has wide application prospects in the technical field of crop planting and aquaculture and is suitable for industrialization large-scale development and usage.

Description

technical field [0001] The invention relates to the technical field of crop planting and aquaculture, in particular to a method for growing crayfish in a lotus root field. Background technique [0002] The lotus root belongs to the subclass of Magnolia, the order of Shanlong. Like temperature, intolerance to shade, not suitable for water shortage, strong wind. The lotus root is slightly sweet and crisp. It can be eaten raw or cooked, and its medicinal value is quite high. Its roots, leaves, flowers, whiskers and fruits are all treasures, and can be nourished and used as medicine. Made from lotus root powder, it can relieve food and relieve diarrhea, appetize and clear away heat, nourish and nourish nature, and prevent internal bleeding. It is a good liquid food and nourishing treasure for women, children, children, and the weak and sick. [0003] Crayfish, also known as Procambarus clarkii, red crayfish and freshwater crayfish, are shaped like shrimp and have a hard shell....
