Method of mixed cultivation in rice field

Abstract

The invention discloses a method of mixed cultivation in a rice field, which comprises the following steps: (1) excavating a circular groove around the rice field, setting an independent irrigation and drainage system, cleaning the field and disinfecting, installing blocking nets at a water inlet and a water outlet, and setting a blocking fence around the rice field; (2) uniformly scattering farmyard manure on the rice field surface, then turning over the rice field to uniformly mix the farmyard manure and soil on the rice field surface, and releasing water to irrigate the rice field for natural fermentation; (3) planting aquatic plants and putting in live margarya melanioides; (4) breeding economical aquatic animals in the circular groove, and scattering baits in the circular groove at regular time; (5) planting rice on the rice field; (6) spraying a compound bacteria preparation in the circular groove every 20-30 days, and irrigating the rice field regularly; (7) harvesting the economical aquatic animals reaching the specification in batches, and supplementing new seedlings of the economical aquatic animals; and (8) harvesting rice. According to the method of the mixed cultivation in the rice field, non-pollution organic rice can be harvested, and the harvested organic rice and fish-prawn-crab products are good in quality.

Description

technical field [0001] The invention belongs to the technical field of paddy field cultivation, and in particular relates to a method for mixed cultivation in paddy fields. Background technique [0002] Paddy farming is an ecological farming model that carries out a virtuous cycle in the paddy ecosystem based on the principles of ecological economics. It is supplemented by artificial measures to grow rice and raise aquatic products, so that water resources, weed resources, aquatic animal resources, Insects, and other materials and energy are more fully utilized, and through the life activities of the aquatic organisms cultivated, the purpose of weeding, insect removal, soil thinning and fertilization for rice fields is achieved, and the ideal effect of mutual benefit and double income of rice fields is obtained. Paddy farming is an efficient ecological production mode that combines planting and breeding. It is a production model aimed at increasing the output rate of paddy f...

Problems solved by technology

However, there are still many insurmountable problems in the co-culture mode, such as insufficient or excess bait, excrement and surplus bait produced in the process of cultivating river crabs accumulate in the water body, insufficient dissolved oxygen, eutrophication of the water body, prevention and control of aquatic product diseases, Reasonable setting of stocking density and other issues, therefore, arranging a suitable breeding system to maximize benefits has become a common trend for farmers and aquaculture researchers

In order to avoid the occurrence of diseases, farmers often need to change a lot of water and use drugs for disease prevention and treatment. A lot of water changes not only waste water resources, but also cause pollution of adjacent waters due to the discharge of aquaculture sewage, which is not conducive to the sustainable development of the ecological environment. Sustainable development; while fish, shrimp and crabs are sensitive to the toxicity of pesticides, in addition, the use of drugs will also cause damage to the ecological environment of the surrounding water bodies
