What kind of beans does soybean mean?
Soybean is commonly known as soybean. Leguminosae is panicum miliaceum, 30-90cm high. According to the color and grain shape of seed coat, soybeans can be divided into five categories: yellow soybeans, green soybeans, black soybeans, other soybeans and feed beans. Soybean likes temperature, the seed germination temperature is 10- 12℃, the optimum temperature is 15-20℃, the growth temperature is 20-25℃, and the flowering and pod setting temperature is 20-28℃.

Pod setting is delayed at low temperature, and flowers cannot bloom below 14℃, but plants will end their growth ahead of schedule at high temperature. Seed germination needs more water, and the soil water content is required to be 70%-80% at flowering stage, otherwise it will increase the bud drop rate. The amount of fertilizer absorbed by soybean before flowering is less than 15% of the total absorption, while the flowering and pod-setting period accounts for more than 80% of the total absorption.

Extended data

1, soybean contains comprehensive nutrients and is rich in content. Every 100g soybean contains 36.3g protein, 8.4g fat/kloc-0, 25.3g sugar and 4 12 calories. 367 mg of calcium, 57 1 mg of phosphorus,1mg of iron, 0.4 mg of carotene, 0.79 mg of vitamin B 1, 0.25 mg of vitamin B2 and 2. 1 mg of nicotinic acid. Protein has 1 times more calcium than the same amount of pork.

2. Soybean has the highest nutritional value among beans, ranking first among hundreds of natural foods, and contains a lot of unsaturated fatty acids, various trace elements, vitamins and high-quality protein. Soybean can be processed into a variety of bean products, which is beneficial food for cardiovascular patients such as hypertension, arteriosclerosis and heart disease. Soybean is rich in protein and contains more amino acids, especially lysine, which just supplements the whole grains.

3. Soybean is rich in phytosterols. After phytosterol enters the human body, it competes with cholesterol in the intestine and can be absorbed more, thus reducing the absorption of cholesterol by the human body. This can not only inhibit the occurrence of colon cancer, but also prevent and treat coronary heart disease.
