Planting method for black soybeans

Abstract

The invention provides a planting method for black soybeans. The planting method comprises the following steps of 1, seed processing; 2, seedling bed preparing; 3, seed sowing; 4, film covering; 5, seedling selecting; 6, fertilizing in a field; 7, weeding in the field; 8, water managing; 9, disease and pest preventing and controlling. According to the planting method for the black soybeans, the black soybeans are planted in selenium-rich soil, and therefore the black soybeans can absorb mineral substances in the soil in the growth process to improve the nutrient ingredients of the black soybeans; in addition, when seeds are sowed, nutrient solutions containing selenium are applied, and therefore the black soybeans can absorb the selenium ingredient in the nutrient solutions in the growth process; furthermore, weed killers with different concentrations are sprayed in different growth periods of the black soybeans, on one hand, unnecessary damage can be avoided in growth process of the black soybeans, on the other hand, the cost can be saved, and meanwhile weeding can be effectively performed; finally, the water spray time and spray amount are controlled according to the fact that different amount of water is needed in different growth periods of the black soybeans, therefore, the survival rate of the black soybeans is improved, and the yield is further improved.

Description

【Technical field】 [0001] The invention relates to the field of agricultural planting, in particular to a method for planting black soybeans. 【Background technique】 [0002] Black beans are rich in nutrition, containing protein, fat, vitamins, trace elements and other nutrients, and also have a variety of biologically active substances, such as black bean pigment, black bean polysaccharide and isoflavones. Black beans have the characteristics of high protein and low calorie, and the protein content is as high as more than 45%. The test found that it contains at least 19 kinds of fatty acids, and the content of unsaturated fatty acids is as high as 80%, of which the content of linoleic acid accounts for about 55.08%. As a kind of unsaturated fatty acid, linoleic acid is a very important essential fatty acid in the human body and plays a vital role in regulating cholesterol metabolism. Only when cholesterol is combined with linoleic acid can it be transported in the body for n...

Problems solved by technology

[0003] At present, the traditional planting method of black soybeans is to use the same concentration of herbicides at different stages of black soybean growth. If the concentration of herbicides is too low, it will not work on weeds. Herbicides can easily damage seedlings and reduce yields; in addition, improper water management during different periods of black soybean growth will also reduce the survival rate of black soybeans, thereby reducing yields. Furthermore, with the improvement of people's living standards, it is hoped that black soybeans contain more nutrients
