Rice-carp symbiotic breeding method

Abstract

The invention relates to a rice-carp symbiotic breeding method, which is characterized by comprising the following steps: (1) selection and treatment of a paddy field: high ridges are built on the four sides of a paddy field, inner ditches are dug between seedbeds, the ridges are provided with a water inlet and a water outlet, a fish gathering pond is arranged in the paddy field, and sound sonar fish driving devices are evenly arranged on the ridges; (2) transplanting of rice seedlings and throwing of fish fries into the paddy field: base fertilizer is applied to the paddy field, the paddy field is covered with a thin layer of soil, quicklime is sprinkled for disinfection, and in a week after disinfection, the paddy field is irrigated from the water inlet, and rice seedlings are transplanted; and (3) prevention and control of rice diseases and pests and fish diseases: the sound sonar fish driving devices on the ridges are opened, feed is thrown into the fish gathering pond, the water outlet is opened to ensure that all fish are driven into the fish gathering pond, and then, pesticide is sprayed onto the rice seedlings or medicine is used in the fish gathering pond. The beneficial effects are as follows: the rice-carp symbiotic breeding method has the advantages of high utilization rate of resources, reasonable planting, pollution reduction and mutually beneficial coexistence; and different medicines are used for rice and fish and are used separately, and the yield and quality of rice and fish stocks are improved.

Description

technical field [0001] The utility invention relates to the field of rice planting methods, in particular to a novel rice carp symbiotic breeding method. Background technique [0002] Rice is the main food production crop in my country with high yield. However, due to unscientific fertilization and management and long-term application of chemical fertilizers and pesticides in traditional rice planting methods in recent years, the growth environment of rice has deteriorated, and the yield and eating quality of rice have declined. In addition, in the traditional rice production activities, the nitrogen, phosphorus, and pesticide residues in the farmland are lost with runoff and the infiltration of the farmland has caused great pollution to the nearby water environment. With the large-scale use of pesticides and chemical fertilizers in the modern agricultural production process, agricultural non-point source pollution has become one of the main causes of surface runoff water po...

Problems solved by technology

[0003] In recent years, rice-fish polyculture has gradually been paid attention to, but the current common rice-fish polyculture technology has problems such as low ability to control diseases and insect pests, unreasonable fish management, etc., so the economic benefits are not high, and there are problems that are difficult to promote
