Rice-fish comprehensive planting and breeding technical method

Abstract

The invention relates to a rice-fish comprehensive planting and breeding technical method. The method is a production method of cultivating and planting ratoon rice after harvesting of single-season rice and continuing fish stocking in the rice field by the utilization of the ecological principle of rice fields. According the ratoon rice, after ripening of the single-season rice, about upper 2 / 3 parts of rice plants are left, ears of rice are picked and the lower 1 / 3 part of the plants and roots is left; after fertilization and cultivation, the second season rice grows out. Breeding of fish inthe rice field runs through the whole process. Melons and vegetables are planted in the ridge, thus creating the three-dimensional circulating rice-fish comprehensive planting and breeding model of ''single-season rice+ ratoon rice + fish'', namely the ''single-season rice+ ratoon rice + fish'' model. The technical method of the invention can be promoted and applied in rice fields in mountainousareas; the bred Sanjiang rice field carp contains rich selenium, which is very beneficial to the human body; and good economic, social and ecological benefits can be obtained.

Description

technical field [0001] The invention relates to a technical method for rice-fishing comprehensive planting and breeding. Background technique [0002] The paddy field and fish breeding mode is an ecological breeding system in which rice and fish are symbiotic, interdependent, and mutually promoting. Biological resources and non-biological resources, and the development of fish farming in rice fields have far-reaching practical significance for promoting science and education, developing high-yield, high-quality, and efficient agriculture. [0003] Rice field fish farming is a traditional rice field farming model in my country, and the comprehensive benefits of planting and breeding can be obtained through the intercropping of aquatic products in rice fields. Rice field fish farming has the advantages of ecological complementarity, multiple uses in one field, and multiple harvests in one field. It does not affect the original rice planting and production, and increases farme...

Problems solved by technology

[0004] Chinese invention patent application 2018102582876 discloses a device and method for three-dimensional planting of regenerated rice and fish, but the planting device in this technical solution is relatively complicated, the cost is high, and the area of ​​the paddy field is fixed, the device is bulky, and it is inconvenient to disassemble , which is extremely unfavorable for promotion and use in impoverished mountainous areas

In addition, the technical solution requires that when the regenerated rice is harvested in the first season, the height of the rice pile should be kept at 35-45cm, which requires a very high rice pile, which is difficult to achieve in the actual planting process.
