Intercropping method of loaches and ricefield eels with selenium-rich rice

Abstract

The invention belongs to the technical field of agricultural planting, and particularly relates to an intercropping method of loaches and ricefield eels with selenium-rich rice. The intercropping method of the loaches and the ricefield eels with the selenium-rich rice is simple and scientific, by means of the loaches and the ricefield eels, weeds in a field can be removed, soil hardening can be prevented, root development and tillering of the rice can be promoted, clear water quality can be maintained, growth of the rice can be promoted, breeding space can be saved, and a good ecological environment can be built; plankton and injurious insects in the rice field can be used as fodder by the loaches and the ricefield eels, so that additional fodder for external use is saved, the breeding cost is greatly lowered, the occurrence rates of diseases and pests of the rice are lowered, and the quality of the rice is improved; the yields are high, the cost is low, and the taste of the loaches and the ricefield eels is good; rice seeds are soaked in a sodium selenite solution, so that pregermination, germination and selenium absorption of the seeds are promoted, and selenium-rich organic fertilizer is applied in the rice planting process, so that the selenium content and the yield of the rice are improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for raising loach and rice field eel with selenium-enriched rice. Background technique [0002] Loach, (scientific name: Misgurnus anguillicaudatus), belongs to Loach family. The body is small, slender, only three or four inches. It is round in shape, short in body, with small scales under the skin, black in color, and covered with its own mucus, so it is slippery and cannot be grasped. Loach and eel are distributed all over China. It is more common in the south and less common in the north. It can be harvested throughout the year, most in summer. Loach and eel can be used fresh or dried after being caught. Edible and used as medicine, loach is called "ginseng in water". It lives in lakes and ponds. It is a fish with high nutritional value. It is different from other fish in terms of appearance, body shape and living habits. It is a kind of ...

Problems solved by technology

Loach and rice field eel are delicious, nutritious, rich in protein, low in fat, and belong to high-protein and low-fat food; the breeding of loach and rice field eel usually chooses special breeding tools or breeding ponds, which require a large amount of feed, high cost, and Nutrient components are single, the yield of loach and rice field eel is low, the quality is poor, and the breeding efficiency is low; and during the growth of rice, there are many plankton and pests in the paddy field, which can provide a variety of feed for the growth of loach and rice field eel, making full use of the land at the same time It can also improve the quality of rice, loach, and rice field eel, and greatly reduce the breeding cost; however, in the process of existing paddy fields, loach, and rice field eel cultivation, it is often necessary to spray pesticides and fertilizers on rice fields, resulting in the quality of loach and rice field eels being affected by pesticides and fertilizers. poor, high mortality
