Rice and shrimp planting and breeding method

Abstract

The invention discloses a rice and shrimp planting and breeding method. The method comprises the following steps of trimming a rice field; installing and debugging a facility; cleaning, disinfecting and fertilizing the field; planting aquatic plants; performing procambarus clarkii fry stocking and temporary rearing management; performing rice planting and daily management; putting brood macrobrachium nipponense; culturing procambarus clarkii; harvesting rice; feeding water to submerge the field; utilizing rice straw; harvesting procambarus clarkii; and repeating the above steps. According to the invention, based on the principle of dual purposes of one water and double harvesting of one field, the novel rice and shrimp planting and breeding method is established by starting from the improvement of the mechanization and intelligence level of rice and shrimp planting and breeding; and while the rice and the procambarus clarkii are utilized and large-scale safe and efficient output of the rice and the procambarus clarkii is effectively guaranteed, the purposes and effects of saving land, water, fertilizer, energy and labor investment are achieved.

Description

technical field [0001] The invention relates to the technical field of paddy field cultivation in agricultural aquaculture, in particular to a method for cultivating rice and shrimp in the aquaculture industry. Juvenile shrimp and rice are co-cropped, water, fertilizer, and chemical spraying drip irrigation are used for targeted and precise supplementation, Macrobrachium japonicus with eggs are continuously released, and the planting and breeding production method combines fast-maturing and decomposing utilization of straw with efficient returning to the field. Background technique [0002] Procambarus clarkii, commonly known as crayfish, is native to the United States and northeastern Mexico in Central and South America. Its white, tender and delicious shrimp meat, rich nutrition, and various cooking methods are deeply loved by consumers in my country. The shrimp was introduced to Japan from the United States in 1918, and then introduced to the Nanjing area of ​​China from ...

AI Technical Summary

Problems solved by technology

Procambarus clarkii is nocturnal, living in bottom dwelling and crawling. It has strong climbing ability and migration ability. It likes to dig holes and burrows and eat tender stems and leaves. Crawfish will cause great harm to rice at the seedling stage. If it is not grown simultaneously with rice in the same field, it will take a period of time for the stocked Procambarus clarkii shrimp to adapt to the rice field habitat and affect its rapid growth. Therefore, it is urgent to solve the problem. Technical problems of "one water, two uses, rice and shrimp two safety" in the early stage of rice and shrimp breeding

[0004] (2) The level of mechanization and intelligence is poor, and it is difficult to achieve the goals of water saving, fertilizer saving, energy saving and safe production

[0005] (3) Insufficient supply of high-quality and cheap live bait, which greatly affects the quality of Procambarus clarkii

The paddy field water space is limited, and the living biological resources in the paddy field habitat are often difficult to effectively guarantee the food demand for Procambarus clarkii culture. In order to significantly improve the quality of Procambarus clarkii cultivation, we should continue to supply high-quality and cheap live bait from exogenous sources depending on the situation. At present, there are no relevant research reports at home and abroad

[0006] (4) The utilization efficiency of rice straw is low, and the waste of resources is serious
