Description

Novel comprehensive rice and fish culture ditch

Technical Field

The utility model belongs to the technical field of agricultural equipment, especially, relate to a novel fish culture ditch is synthesized to rice fishing.

Background

At present, with the great support of the Ministry of agriculture, the national population of aquatic technologies actively explores a new comprehensive rice and fish breeding mode of promoting rice, stabilizing grains, improving efficiency, ensuring quality safety and ecological environment protection under the basis of several fish breeding developments in rice fields, successfully summarizes new modes and new technologies of rice-fish, rice-crab, rice-shrimp, rice-frog, rice-loach and the like, and obtains good effects of rice yield stabilization, increase of income of farmers (fishers), pesticide and fertilizer, and great reduction of use of fishery and medicine feeds. The comprehensive planting and breeding of rice and fishery is a modern ecological cycle agricultural development new mode with various functions of grain stabilization, fish promotion, efficiency improvement, quality improvement, ecology and the like, and is vigorously popularized in various places at present. The comprehensive planting and breeding of rice and fish can not only separate bodies to utilize water layer resources, but also fertilizer fish with abundant plankton in the field, and the excrement of the fish can also fertilizer the field to increase rice, thus the method belongs to a typical biological chain virtuous cycle mode. However, in the field engineering construction of comprehensive rice and fish planting, the reports are different in every place: firstly, raising, widening and reinforcing ridges around a rice field by utilizing excavated earthwork in a fish ditch, tamping every layer of soil when the ridges are reinforced, and not performing solidification slope protection treatment on the ridges and fish pits of the fish ditch; and secondly, hardening the inner side of the transformed ridge and the other side of the fish ditch by adopting cement concrete to form a permanent field foundation and a permanent fish ditch. The first soil field is hard and not firm, heavy rain falls off, finless eels, crayfishes, water snakes and mice are punched, soil on the inner wall of the fish ditch is easy to collapse, the culture effect is seriously influenced, fertilizer and water leakage is caused, and the fish escape phenomenon is serious; the second type is firm, but has too high engineering cost and difficult reclamation, and is not environment-friendly.

In summary, the problems of the prior art are as follows:
