Paddy field, crayfish and loach coupling planting and breeding method

Abstract

The invention provides a paddy field, crayfish and loach coupling planting and breeding method. The method comprises the following steps that a field is selected, ditches are arranged on the periphery of the field, and a crayfish A area, a loach area and a crayfish B area are arranged in the field; the crayfish A area and the crayfish B area are each provided with a plurality of crayfish ditches; the loach area is provided with a plurality of mud holes; rice seedlings are planted in the crayfish A area, the loach area and the crayfish B area respectively, fertilizer I is applied 3-7 days later, and loach larvae are put 25-35 days after the rice seedlings are planted; 40-45 days after the rice seedlings are planted, crayfish larvae are put; a complex microbial agent is sprayed every 25-35 days, the complex microbial agent is prepared from bacillus subtilis powder, trichosporon and lactobacillus powder, and the crayfish and the loach are harvested after the rice is harvested in the rice harvesting period. By means of the planting and breeding method, growth of the crayfish, the loach and the rice is promoted mutually, the yield is remarkably increased, meanwhile, the specifications of the crayfish and the loach are improved, the loach and the crayfish are easy to capture, and the yield per mu is remarkably increased.

Description

technical field [0001] The invention relates to the technical field of paddy field, crayfish and loach breeding, in particular to a method for coupling paddy field, crayfish and loach breeding. Background technique [0002] Rice (Oryza sativa L.) is a cereal crop of the Oryza genus. Rice is one of the important food crops in my country, especially in the south of my country. Crayfish (Procambarus clarkii) is an aquatic animal of the class Crustacea, decapod order, and crayfish family. It is widely welcomed by people because of its delicious meat. Loach (Oriental weatherfish), belonging to the genus Loach in the Loach family, has tender meat, delicious taste and rich nutrition. Microorganisms and pests produced during rice production are the food of crayfish, and the excrement of crayfish is also the fertilizer of rice, feeding back the growth of rice. The combination of rice and shrimp breeding has increased economic income. CN111990303A discloses a method for cultivatin...

Problems solved by technology

CN111990303A discloses a method for cultivating Australian freshwater crayfish in rice fields, which improves the yield of crayfish and rice, but is not suitable for the symbiosis of rice fields, crayfish and loaches

However, in the existing breeding mode, the breeding effect of crayfish and loach is not good enough, and the disease resistance is not strong enough, and it is easy to have adverse effects on each other when the disease occurs, which makes it difficult to increase the production of rice and crayfish.
