Ecological floating bed for treating nitrogen and phosphorus pollution of water based on deep rice planting

Abstract

The invention provides an ecological floating bed for treating nitrogen and phosphorus pollution of water based on deep rice planting. The ecological floating bed is used for solving the problem thatnitrogen and phosphorus pollution of different depths in the water body is difficult to treat in the prior art. The ecological floating bed comprises a frame and a cultivation unit, the frame floats on water, a plurality of cultivation holes are uniformly distributed in the frame and correspond to one cultivation unit, the accommodating box is connected with the matrix accommodating box through aflexible net cylinder, the matrix accommodating box floats up and down, the limiting assembly can limit the underwater depth of the matrix containing box, the buoyancy adjusting assembly is fixedly connected to the outside of the matrix accommodating box, the buoyancy of the buoyancy adjusting assembly is adjustable, so that the matrix accommodating box floats up or sinks down, the floating part is limited and fixed by the limiting assembly during floating, by adjusting the buoyancy of the buoyancy adjusting assemblies in the different cultivation units, the substrate containing boxes of the different cultivation units are different in underwater depth, roots of deep rice of different depths can absorb nitrogen and phosphorus elements in water, and therefore the content of nitrogen and phosphorus in water of different depths can be reduced, and growth of the deep rice can be promoted.

Description

technical field [0001] The invention relates to the technical field of agricultural ecology and water environment treatment, in particular to an ecological floating bed for controlling nitrogen and phosphorus pollution in water bodies based on deep-water rice planting. Background technique [0002] Double-cropping rice areas mainly include 10 provinces, municipalities and autonomous regions including Jiangxi, Hunan, Hubei, Guangdong, Guangxi, Zhejiang, Hainan, Yunnan, Anhui and Fujian. The land reclamation index in this area is high, and it is an important production and export base of grain and agricultural products in my country. With the development of economy and society, the agricultural and rural economy in this area has made great progress. At the same time, it has also brought about the increase in the use of external agricultural inputs such as chemical fertilizers, pesticides, and agricultural films, and the increase in agricultural waste such as livestock and poul...
