Selenium-rich rice and loach intercropping method for saving baits

Abstract

The invention belongs to the technical field of agricultural planting and particularly relates to a selenium-rich rice and loach intercropping method for saving baits. The selenium-rich rice and loach intercropping method for saving baits is simple and scientific, loaches can remove weeds in fields, prevent soil hardening, promote rice root system development and tillering, keep water clean and promote rice growth, a breeding space can be saved, and a good ecological environment can be established. The loaches can utilize planktons, injurious pests and the like in rice fields as baits, externally added baits are saved, the breeding cost is greatly reduced, the occurrence rate of rice diseases and pests is reduced, and rice quality is improved. The yield is high, the cost is low, and the loaches are good in taste. Rice seeds are soaked by a sodium selenite solution, seed germination acceleration and selenium element absorption are promoted, a selenium-rich organic fertilizer is applied in the rice planting process, and the selenium content and yield of rice are increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for nesting selenium-enriched rice and loach which saves bait. 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 is 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. After the loach is caught, it can be used fresh or dried. Edible and used as medicine. Loach is called "ginseng in the 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 special kind of loa...

Loach is called "ginseng in the 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 special kind of loach. Loach meat is delicious, nutritious, rich in protein, low in fat, and belongs to high-protein and low-fat food; loach farming generally chooses special farming tools or ponds, which requires a large amount of feed, high cost, and single nutrient content. The yield of loach 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 make full use of the land while improving the quality of rice and loach , greatly reducing the cost of breeding; however, in the existing paddy field and loach breeding process, the paddy field often needs to be sprayed with pesticides and chemical fertilizers, resulting in poor quality and high mortality of loach due to the influence of pesticides and chemical fertilizers
