A soybeans profile
The soybeans are also called soybeans, mashed beans, horse beans, soybeans, varieties of winter beans, soybeans, four season beans, and are mainly produced in the north-east. China's ancient name is zirconium, a crop whose seeds contain abundant protein. The soybeans are elliptical, spherical, yellow, light green, black, etc. Soybeans are most often used for various bean products, soy oil extraction, soy sauce and protein extraction. Soybeans, which are also used in animal feed, are soybean slags or made of powder. Soybeans generally refer to their seeds. The skin colours and granules of soybeans are divided into five categories: soybeans, soybeans, black soybeans, other soybeans (coloured soybeans with brown, brown, red, etc.), soybeans (general seed grains are small, flat elliptical, two leaves have dented dots, and the skin is slightly luminous or non-skinned)。
Soybeans are well drained, rich in organic, soil ph6. 2-6. 8. It's time for the early broadcast. More fat and nitrogen is four to five times more than grains at the same production level. Zirconium periods pay attention to timely irrigation and drainage. Soybeans are self-plowing crops, and pure breeding is still practised in some areas. Rrt has been very effective in improving the disease resistance of varieties. The main method of soybean breeding in china is mixed variety. The spectral method is used to select future generations。
Soybeans' efficacy and effects
Soybeans don't just mean soybeans, but they also contain black beans and green beans. Soybeans are fully nutritious and rich, with proteins two times higher than pork and 2. 5 times higher than eggs. The protein content is not only high, but also of good quality. The amino acid composition of soybeans proteins is similar to that of animal proteins, where amino acids are closer to the margin required by humans and are easily digested. If soy and meat foods are combined with egg foods, their nutrition is comparable to that of eggs, milk and even more than that of eggs and milk。
Soybean fats also have high nutritional value, and they contain many unsaturated fatty acids that are easily absorbed into humans. And soybeans fat can prevent cholesterol absorption, so so soybeans are an ideal nutrient for people with arterial sclerosis。
The soybeans contain a wealth of inorganic salt such as calcium, phosphorus, magnesium and potassium, as well as trace elements such as copper, iron, zinc, iodine and molybdenum. Calcium, phosphorus and proteins in soybeans are combined and easily absorbed into humans; iron and iodine are important to the human body; iron-deficits are anaemic; people with iodine deficiency suffer from thyroid swelling; and micronutrient molybdenum inhibits carcinogenicity。
The nutrients contained in soybeans are comprehensive and abundant, with 36. 3 grams of protein, 18. 4 grams of fat, 25. 3 grams of sugar, 412 kilocalories of heat, calcium 367 mg, phosphorous 571 mg, iron 11 mg, carrot 0. 4 mg, vitamin b10. 79 mg, vitamin b20. 25 mg, nickel acid 2. 1 mg, 1 times more protein, 33 times more calcium, 26 times more iron and much less expensive than pork。
Soybean proteins contain a variety of amino acids necessary for humans, in particular lysine, light amino acids, sour acids and sour acids. This is the opposite of general cereals. As a result, soybeans and food blends can complement each other, greatly increasing their nutritional value. Soybeans contain a lot of fat. And for unsaturated fatty acids, especially with the most abundant levels of subsyroid acids. This has contributed significantly to the prevention of artery sclerosis, with soybeans containing approximately 1. 5% phosphorous resin. Phosphorus is an essential component of the cell. It has an important role to play in maintaining the health of the human nervous, liver, bones and skin。
Soybean planting techniques
Varieties selection
Depending on local ecological type and market demand, suitable, high-yielding, high-quality, resilient and resilient varieties have been selected, such as the spoon bean 21, the spring bean 22 and the spring bean 23. Change every three years。
Seed processing
Seed wrapping: the choice is to make seed wrappings with high-quality seeding agents, which are operated with minimum exposure to metals, with dry and late seed planting of the wrapping seeds, which increases the resistance of the seeds。
Acid soils grow soybeans, with ammonium molyte mixed seeds, with 1 to 1. 5 grams of ammonium molyte per kilogram of soybeans seed, and 1 to 1. 5 per cent of ammonium molyte solution is sprayed on the surface of the seeds and dried and planted。
♪ to till the ground ♪
Rice fields are grown with spring soybeans, tilling before the winter, ploughing two to three metres wide, opening ditches, gutters, gutters and fine springs. The soil is required to be thin, clean and flat. Dry land that is free in the winter, till before the winter, grow vegetables in the dry land in the winter, till in the clear days after the harvest of vegetables, and then open ditches two to three metres wide and fine。
Seeding
The seeding began at an average daily temperature of 10-12°c in the 5 cm earth layer, and the mid- and low-altitude areas were suitable for planting at the end of march and the beginning of april. Caves, 27 to 33 centimetres in range, 17 to 20 centimetres in range, sowing three or four seeds per den, with thin covers (three or four centimetres thick). The planting density is determined by the characteristics of the species and by the conditions of water fattening, with the pre-maturized varieties growing between 30,000 and 40,000 plants per 667 square metres, the medium-preparated varieties planting between 25,000 and 35,000 plants and the late-defined varieties planting around 20,000 plants。
Fertilizing
The bottom fertilizer is 400 kg of organic weight for farmers per 667 m2 and 36 kg of urea for phosphorus and 100 kg of urea for marginal soils. Farmers apply organic fertilizers before the ground is cleared, and they are rolled into the cropping layer through ground and cropland, where they are applied and integrated with the soil. Bottom fertilization can also be systematically applied to soybeans when they cannot be applied to them as a result of cropping or farming season arrangements. Fertilizers were 150 kg of organic fertilizer per 667 m2 for fertilized farmers, 4. 6 kg of urea and 10 kg of potassium chloride. No nitrogen fertilizer can be applied to land where soil fertility is high or where a large number of quality farmers have been applied. The method of application is the application of fertilizers into seed dens, with depths ranging from 8 to 10 cm, and the separation of fertilizers and seeds from the soil, which prevents the burning of seedlings and provides sufficient nutrients for soybean seeding and promotes early delivery. Or you can make fertilizers and earth composts and then use them as cover seeds. In soils with medium- and low-fertility levels, following up during seed seasons combined with the first planting of grass, 5 kg of urea per 667 m2 application, or 10 kg of nitrogen, phosphorus, potassium compound fat, or 250 kg of manure, nitrogen fertilizer can also be spread in the canals four or five centimetres away from the soybean plant before or after the rain, but it is taboo that the fertilizer is directly exposed to the soybean plant to prevent the burning of seedlings. Weakly grown soybeans, which are better followed up before or during flowering. For 75 kg of urea per 667 m2, nitrogen fertilizer should be taken before or after rain, but care should be taken to prevent direct contact between the fertilizer and the plant。
Field management
1: migration of seedlings. Land parcels, which are generally short of seedlings, can be replanted locally. The soil should be so intense as to be less humid and watered to ensure survival. In order for seedlings that are replanted to grow rapidly, they should be properly followed up and strengthened. If there is a serious shortage of seedlings, it will be directly replanted。
2: sapling, seedling. At the time of the 2 single leafs, the first leaf is fully distributed. It should eliminate weak, sick and mixed strains and retain strong ones。
3: weed cultivation in china. The first medium tillage usually takes place when the first leaf appears and leaves are not dropped, and the second medium till the tree is about 20 cm tall and leaves are not sealed. The first one was shallow, the second was slightly deeper and combined with the pursuit of fertile soil。
4: irrigation. In the case of high-temperature drought, water should be irrigated in due course. It is appropriate to wet the trenches to prevent the flooding from causing soil slabs。
