A farmland balance control system and agricultural wetland circulation system

Abstract

A farmland balance regulation system and an agricultural wetland circulation system. The invention relates to the technical field of eco-agriculture. The farmland balance regulation system includes, in a successively communicated manner, an irrigation water pretreatment system, a farmland shallow water wetland system, an ecological ditch, and a region multi-pool system. The irrigation water pretreatment system includes, in a successively communicated manner, a primary settling tank, a mixing and blending tank, and a lifting and water distribution system. A detection system is arranged in the mixing and blending tank. The agricultural wetland circulation system includes farmlands and a water distribution system. The water distribution system includes a water inlet pipe, a water distribution pipe system, and a water outlet pipe. The water inlet pipe is communicated with the water distribution pipe system. The water distribution pipe system and the water outlet pipe are arranged in the farmlands. The water outlet pipe is provided with a water level control valve. The ecological ditch includes a bottom wall, a first side wall, and a second side wall. Aquatic plants are planted on the bottom wall. Baffle plates are arranged in the ecological ditch at interval in the water flowing direction. A water flowing gap is formed between the bottom wall and the baffle plates. The region multi-pool system includes a plant facultative pool. The agricultural wetland circulation system includes the farmland balance regulation system. The two systems can achieve recycling utilization of irrigation water, thereby saving water source.

Description

technical field [0001] The invention relates to the technical field of ecological agriculture, in particular to a farmland balance control system and an agricultural wetland circulation system. Background technique [0002] Both aquaculture biogas slurry and domestic sewage contain a large amount of fertilizer substances, which have a good effect on promoting the growth of crops. Not only can the use of pesticides and fertilizers be reduced, but also the negative effects on soil and crops caused by excessive use of chemical fertilizers and pesticides can be avoided. [0003] The inventors of the present application have found through research that directly using aquaculture biogas slurry or domestic sewage to fertilize crops will have serious negative effects on crops and hinder the normal growth of crops. The aquaculture biogas slurry must be pretreated before it can be used for crop fertilization. [0004] The existing farmland irrigation system cannot realize the full u...

AI Technical Summary

Problems solved by technology

[0004] The existing farmland irrigation system cannot realize the full utilization of aquaculture biogas slurry or domestic sewage, and cannot realize the recycling of water resources. The demand for supplementary irrigation water is very large, and it is easy to cause waste of water resources.
