Rice and crab comprehensive planting and breeding method

Abstract

The invention belongs to the technical field of agricultural production, and discloses a rice and crab comprehensive planting and breeding method. The method comprises the steps of farmland selection,planting and breeding area construction, rice seed selection, base fertilizer application, rice field management, topdressing, selection of young rice crabs, rice field treatment, stocking of the young rice crabs, young rice crab management, rice crab management and water quality management. The rice planting mode adopted by the invention can make full use of the rice border advantages to achievethe ventilation and light transmission effect to the maximum extent, and reasonable close planting achieves the effect of increasing both production and income; early temporary culture, early bait casting and early culture field entering are adopted for river crab culture, river crabs can eat grass buds, worm eggs and larvae, the effects of weeding without chemicals and ecological insect pest prevention are achieved, meanwhile, river crab excrement can fertilize soil, the field soaking process is omitted, and the cultured river crabs are large in specification, good in taste and quality and high in price; and the effect of mutualistic symbiosis is achieved, and the economic benefit is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a method for comprehensive cultivation and breeding of rice and crab. Background technique [0002] At present, land resources and water resources are the most important resources for human food security. With the increase of population and the increase of food requirements, the land resources and water resources used to develop agricultural production are increasingly in short supply. How to broaden the space for resource utilization and improve resource utilization The utilization efficiency of paddy fields is an important land resource for food production. The shallow water environment of paddy fields can provide habitats for aquatic organisms such as fish, shrimp, crabs and soft-shelled turtles. The use of paddy fields to breed aquatic organisms has a long history in my country. One field with two harvests, one water with two harvests, coupled with h...

Problems solved by technology

[0002] At present, land resources and water resources are the most important resources for human food security. With the increase of population and the increase of food requirements, the land resources and water resources used to develop agricultural production are increasingly in short supply. How to broaden the space for resource utilization and improve resource utilization The utilization efficiency of paddy fields is an important land resource for food production. The shallow water environment of paddy fields can provide habitats for aquatic organisms such as fish, shrimp, crabs and soft-shelled turtles. The use of paddy fields to breed aquatic organisms has a long history in my country. One field with two harvests, one water with two harvests, coupled with high quality and high price, quality increase, etc., the actual income of farmers has increased significantly, but in the existing rice, rice and crab production mode, there is a high breeding density, which is easy to cause water environmental pollution, and the rice The planting area is squeezed, affecting the normal growth of rice, thus restricting the development of rice farming industry

[0003] Through the above analysis, the problems and defects in the prior art are: (1) in the existing rice crab production mode, there is a large breeding density, which easily causes water body environmental pollution; (2) the planting area of ​​rice is easily squeezed, It affects the normal growth of rice, thus restricting the development of rice farming
