Wild rice shoot and freshwater crayfish joint ecological culture method

Abstract

The invention discloses a wild rice shoot and freshwater crayfish joint ecological culture method. A main ridge with a height of 1 to 1.5m is arranged around a wild rice root field to enclose the wild rice root field to form a water storage mechanism; and multiple ridges are arranged in parallel in the wild rice root field enclosed by the main ridge, and row trenches are arranged between adjacent ridges. Besides, the top portion of one side of each ridge is provided with a baffle plate higher than the ridge by 15 to 20cm, the ends, which are opposite, of the adjacent ridges are respectively connected with the main ridge, an interval distance of 0.5 to 1m is arranged between the other ends and the main ridge, and an S-shaped current passage formed by arranging the ridges in a staggered mode is formed; and a water circulation system enables water to flow circularly in the form of an S in the row trenches in a plot. Isolation nets are arranged in the row trenches, the side walls of the isolation nets are attached to the side walls of the row trenches, and the top portions of the isolation nets are higher than the ridges by more than 2cm; and the top portions of the isolation nets are provided with cover nets for enclosing the isolation nets.

Description

technical field [0001] The invention relates to the technical field of freshwater crayfish culture, and more specifically, the invention relates to a co-culture ecological system of wild rice stems and freshwater crayfish. Background technique [0002] Zizania is a perennial herbaceous plant of the genus Gramineae. It contains protein, fat, sugar, and various vitamins and minerals. It has the functions of clearing away heat, detoxification, and smoothing the skin. It is a special vegetable in my country, and its demand is gradually increasing. Cultivation and planting have good prospects. At present, Zizania zizania plantation generally adopts a single planting model. [0003] Freshwater crayfish, scientific name Procambarus clarkii (Procambarus clarkii), is a kind of shrimp with considerable economic value. Breeding crayfish in Zizania fields can organically combine planting and aquaculture, and make full use of the artificially created ecosystem to make crayfish and Zizan...

AI Technical Summary

Problems solved by technology

However, because crayfish like to dig holes, it is easy to cause damage to the roots of Zizania and Zizania. In addition, although crayfish have strong adaptability, the quality of water is of great significance to the quality of crayfish. The water is still, and the application of organic fertilizers tends to cause poor water quality and low oxygen content in the water, which affects the quality of crayfish. Therefore, there is no relevant report on the co-culture of Zizania and freshwater crayfish.
