Paddy field fish ecological breeding method and paddy field fish ecological breeding rice field

Abstract

The invention relates to the field of rice field fish breeding, in particular to a paddy field fish ecological breeding method and a paddy field fish ecological breeding rice field. According to the method, astragalus smicus is planted in a paddy field to serve as early rice base fertilizer, soil organic matter is increased, the physical structure of soil is improved, and fertility of soil and field water is improved; duckweed is cultivated in the rice field, can be used as green manure of the rice field and fish food, and can prevent weeds from growing; rice absorbs the fertilizer, purifies the water quality and provides rich rice spike resources for fingerlings; and duckweed, zooplankton and the like can grow out through the water fertilizer for fishes to take in nutrition. The fishes are bred freely, and rice ears, weeds, plankton, pests and the like in the paddy field can be eaten; and fish excrement returns to the field to become fertilizer, the effects of not spraying pesticide or adding chemical fertilizer and increasing benefits are achieved, a virtuous cycle is formed, the labor intensity and labor cost of farmers are greatly reduced, and good economic benefits and social benefits are achieved.

Description

technical field [0001] The invention relates to the field of paddy fish farming, in particular to a method for ecologically cultivating rice flower fish and a paddy field for ecologically cultivating rice flower fish. Background technique [0002] Rice-fish farming is an ecological farming model in which rice-fish symbiosis, interdependence and mutual promotion are carried out in a virtuous cycle in the rice field ecosystem according to the principles of ecological economics. Use the water surface of the paddy field to raise fish, use the rice ear resources, water resources, weed resources, aquatic animal resources, and other materials and energy in the paddy field to be more fully utilized by the farmed fish species, and through the life of the farmed fish species activities to achieve the effects of plowing and weeding, reducing pests and diseases, and achieving mutual benefit and double income increase of rice and fish. [0003] Carp has strong adaptability, cold resista...

Problems solved by technology

[0005] In the existing paddy field fish farming technology, the paddy field is not fertile enough to meet the growth needs of fish, and additional feed needs to be fed, and the output is small and the benefit is poor; or in the process of fish farming, it is still necessary to add fertilizer to control water and soil. Fertility, resulting in over-fertilization of water quality, rice lodging, affecting the ecological environment in the paddy field
