Rice and shrimp comprehensive planting and breeding method for improving rice yield

Abstract

According to the rice and shrimp comprehensive planting and breeding method capable of improving the rice yield, the ridge is heightened, the grooves are arranged to be small in upper portion and large in lower portion, the lowest water requirement of crayfish can be met, meanwhile, rice field drying is conducted, the contradiction between the water requirement of the crayfish and rice field drying is adjusted, the shape of a rice planting area is arranged to be a pentagon or more, and the yield of the crayfish is increased. A place is provided for daily activities of the crayfish, the small slope is arranged on the edge of the rice planting area, so that the rice is fully illuminated, the quality of the rice is improved, and buffering can be provided for flowing of a water body. The organic fertilizer and the water quality improver are prepared from the weeds in the rice field, the utilization approach of the weeds is developed, the source is wide, and the cost is low; the organic fertilizer disclosed by the invention can meet the nutritional requirements of growth and development of rice, promote photosynthesis of the rice and improve the yield and quality of the rice, and the water quality improver disclosed by the invention can effectively improve the water quality and maintain a good water quality environment.

Description

technical field [0001] The invention relates to the technical field of rice-shrimp co-cropping, in particular to a rice-shrimp comprehensive planting and breeding method for improving rice yield. Background technique [0002] The rice and shrimp breeding mode is to plant rice in the paddy field while stocking crayfish. The feeding activities of the crayfish are used to remove the eggs of weeds in the paddy field and reduce the occurrence of rice diseases and insect pests. The paddy field also provides a place for the daily activities of the crayfish. Make full use of The rice and crayfish produced are all green and organic food, which is a green and ecological farming model. Such as Chinese patent CN106259086A, a kind of rice and shrimp co-cropping ecological breeding method, and Chinese patent CN109937935A, a kind of efficient rice field lobster breeding method. However, crayfish are sensitive to pesticides. In rice and shrimp fields, the use of pesticides and chemical fer...

AI Technical Summary

Problems solved by technology

However, crayfish are sensitive to pesticides. In rice and shrimp fields, the use of pesticides and chemical fertilizers should be avoided as much as possible. Rice diseases are prone to occur, and the growth of crayfish requires a large amount of water, while the growth of rice requires multiple dryings. , the water demand is contradictory. If it is to meet the water demand of crayfish, it will not be able to dry the rice field in time.

[0003] At present, the output value of crayfish is relatively large, and most of the existing rice-shrimp co-production models focus on crayfish farming, but rice is an important food crop, and it is necessary to study the cultivation of rice while cultivating crayfish, so , it is necessary to develop a comprehensive rice and shrimp breeding method to improve the rice yield of rice and shrimp fields
