Rice and crayfish ecological co-culturing method

Abstract

The invention discloses a rice and crayfish ecological co-culturing method. According to the method, field ridges are built around a rice field, the water content in the rice field is increased for facilitating the growth of crayfish, and aquatic plants are planted to provide habitat and concealed places for the crayfish, so that a good growth environment is created for the crayfish. Meanwhile, after the crayfish are caught, organic fertilizers are added for rice production through metabolism products of the crayfish, so that rich organic fertilizers can be provided for the growth of rice, andthe use amounts of chemical fertilizers and pesticides in a rice planting process are reduced. The growth of the rice and crayfish is mutually promoted, and meanwhile, the space of the rice field iseffectively utilized. In the aspect of water quality retention, organic components contained in soil and feed are decomposed into ammonia, so that the ammonia nitrogen content in the water is increased, and the water is easily eutrophicated. A multi-microbial biological agent is sprayed to the water regularly, and the ammonia nitrogen in the water can be fixed and converted through biological metabolism of bacillus, photosynthetic bacteria, nitrifying bacteria and actinomycetes in the biological agent, nutrition is provided for the growth of the rice, and meanwhile the ammonia nitrogen contentin the water is reduced. The crayfish cultured by the method disclosed by the invention is fast in growth and regular in specification, normal production of the rice is not influenced, the paddy field is used for two purposes, and incomes are greatly improved.

Description

technical field [0001] The invention relates to the field of crayfish culture, in particular to a method for ecological co-culture of rice and shrimp. Background technique [0002] Crayfish breeds fast, has a short breeding cycle, and at the same time has delicious meat, rich nutrition, large market demand, broad development prospects, high economic benefits, and widely exists in freshwater ponds in my country. However, due to serious water pollution, the quality of wild crayfish has been seriously affected; at the same time, overfishing of wild resources and backward artificial breeding techniques have caused the degradation of germplasm resources and the decline in production. In order to meet the market demand, more and more people began to try ecological farming, but the current rice field farming methods and models are improper, and the crayfish produced are generally small in size, poor in color and have many diseases, which makes the survival rate of crayfish Both pr...
