Method for constructing comprehensive rice planting and fish culture ditches

Abstract

The invention belongs to the technical field of construction of fish culture ditches in rice fields, and discloses a method for constructing comprehensive rice planting and fish culture ditches. The method for constructing the comprehensive rice planting and fish culture ditches comprises the following steps: making a frame on a ridge and a fish ditch by using angle steels and cement tiles, and the filling the frame with soil; digging a fish ditch at the periphery of the ridge, digging one or more parallel longitudinal and transverse fish ditches according to the size and the shape of a rice field, wherein the ditches communicate with one another; constructing a fish nest at one corner or in the center of the rice field, and connecting at least one channel of the fish nest with the fish ditches; and mounting fish blocking equipment at a water inlet and outlet opening. The method has the advantages of firm ridge, strong water retention and fertilizer retention, convenience in drainage and irrigation, flood control, drought prevention and tidy and beautiful integral engineering. Moreover, the surface of the field has a water level with a certain height, the three-dimensional space for fish movement is increased, the leakage of the field ridge is prevented, and fish running in heavy rain is prevented.

Description

technical field [0001] The invention belongs to the technical field of fish-raising ditch construction, and in particular relates to a method for constructing fish-raising ditch for rice-fishing comprehensive breeding. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: Since the new century, with the strong support of the Ministry of Agriculture, the National Aquaculture Technology Promotion Headquarters has actively explored "promoting rice with fish and stabilizing grain" on the basis of previous rounds of rice-fish farming development The new model of rice-fishing comprehensive planting and breeding of efficiency, quality and safety, and ecological environment protection has successfully summarized new models and technologies such as rice-fish, rice-crab, rice-shrimp, rice-frog, rice-loach, etc. The good effects of stable production, increased income of farmers (fishers), and a substantial reduction in the use...

AI Technical Summary

Problems solved by technology

[0004] To sum up, the problems existing in the prior art are: the soil field is hard and firm, the heavy rain washes away and the eels, crayfish, water snakes, and rats make holes, and the soil on the inner wall of the fish ditch is easy to collapse, seriously affecting the breeding effect, and fertilizer leakage Water leakage and fish escape are serious; although the permanent field foundation and fish ditch are solid and firm, the project cost is too high, and reclamation is difficult and not environmentally friendly
