Calcium-rich black soya bean cultivation method

Abstract

The invention belongs to the black soya bean plantation field, and specifically relates to a calcium-rich black soya bean cultivation method comprising the following steps: A, seed processing: selecting plump seeds, airing the seeds for 2-3 days, dissolving 0.8-1.2g borax into 30ml water for per kilogram seeds, mixing the seeds with the solution, drying the seeds in shade, and sowing the seeds; B, soil working and fertilizing: selecting sandy soil, applying 1000-2000kg organic fertilizer in per mu field, and rotary tillaging at the depth of 20-23cm; C, opening holes and sowing: sowing 1-2 seeds in each hole according to the sowing depth of 3-4cm, line space of 10-15cm and plant space of 45-60cm, so 10000-12000 plants can be sowed in each mu; D, field management: spraying 0.5% calcium chloride solution for one time on leaves at the black soya bean early flowering period and seed filling period. The calcium content of the black soya bean produced by the method can be stabilized between 520-610 microgram / 100g, thus greatly enhancing black soya bean health care effect.

Description

【Technical field】 [0001] The invention relates to the field of black soybean planting, in particular to a cultivation method of calcium-enriched black soybean. 【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%, which plays a vital role in regulating cholesterol metabolism. [0003] Calcium is an essential element in large quantities for the human body. It is the fifth most abundant element in the human body, accounting for about 1.7% of body weight. It not only participates in the formation of bones and teeth, but ...

However, the calcium content in the staple food crops and vegetables of the Chinese people is not enough to supply people's daily needs, and the calcium content of the Chinese diet is only half of the recommended value

[0004] According to data analysis, the calcium content in the existing black soybean varieties is generally below 250 micrograms / 100 grams, which is difficult to meet the needs of the human body for calcium elements, and there are no relevant reports on the cultivation methods of calcium-enriched black soybeans at home and abroad.
