As a cash crop in our country, soybeans are grown more widely, with soybeans in a variety of varieties, such as soybeans, soybeans, soybeans, soybeans, soybean foods, soybean oil, soy sauce, protein, etc., which the rural children in the 1970s and 1980s used to unearth and roast directly on the fire, which is not understood by the children who are now
The soybeans have grown over 5,000 years of history and are known for their nutritional wealth as “the king of the soybeans”, “the meat in the fields”, but soybeans are also a particularly delicate crop, which is afraid of drought and flooding, and which, in a slightly inappropriate environment, will not open flowers. Today, we use six adages to understand how the soybeans are grown, and welcome to view them。
One, summer to three days to grow soybeans
The saying is that the time of soybean cultivation, with soybean planting occurring after the summer to three days, is the time when wheat harvesting is complete, the crotching is the best, both for soybean growth periods and for growing temperature needs. The soybean is a warm and radiant crop with the most appropriate temperature of 20-25°c, the most appropriate temperature for flowering is around 27°c, and the temperature for seed sprouts is 16°c, so the best time for soybean cultivation is three days after the summer to air break, around 21-22 june each year。
Ii. No ploughing for wheat-cuttering beans and rain on the floor
The saying is that planting soybeans without a plowing, can be done more effectively if soybeans are sowed before a rain event, because soy seeds are hard, have poor water intake capacity and have weak roots when they germinate, slow uptake of the organic matter in the soil, much of the north is done with wheat, straw is returned to the field and sowing directly, which greatly reduces irrigation water, and the organic matter of the soil is not lost, while the cost of labour is reduced, and the soil is then broken。
Three, if you want the beans, you can plant them on land
The saying is that soybeans have a high rate of soybean soybean soybean seeding, because soybeans are double-leaf plants, and when their seeds germinate, they produce two green leaves, which, if sorely sow, they leave the ground with their leaves, making it difficult to break the earth floor, turning into yellow seedlings, weak seedlings, and soybeans too deep, hot and rain, and soybeans rot in the soil, thus causing a severe shortage of soybean seedlings in the fields, generally at a depth of three to five centimetres, so that the soybeans sow in sufficient temperature and oxygen to so that they ger。
Four, not so thin
The saying is that soybeans should be planted in a rational manner, with a distance of about a mile, with an adult opening his mouth, a thumb between his finger and his finger, about 18 centimetres. Of course, attention should also be paid to soybean varieties, with a large number of branches and a small intensity of plant cultivation; small branches, with a high intensity of cropping, and the principle of “fat, thin, lean” and, generally, a density of about 15,000 to 30,000 soybeans per acre。
Five: the years of the bean field, the years of the beans
The saying is that soybean cultivation is heavily taboo, with rotation, with the conditions of the best water and dry rotation, soybean production is high because the root of soybean is circulated organic acid, which reacts chemically with heavy metals in the soil, produces toxic substances, leads to a decrease in soil fertility, and soybean roots are immersed in a variety of pathogens and insect eggs, which do not plough, leading to an increase in field disease and, more importantly, heavy cultivation, where potassium and nitrogen in the soil are not sufficient to satisfy the growth of soybeans, causing soybean strains to be thin, non-flowering or floughing, thereby reducing soybean production and quality。
Six, three times the bean bean bean bean
This saying means that the soybean is managed three times with a soybean soybean soak, in order to be productive and productive, in some cases in the local saying, “three times a soybean soybean,” because the root of soybean is short and dense, which must ensure that the soil is permeable and that weed must be eradicated in order for the soybean to grow well, and the soybean to grow well, and the soybean soybean has a “triple moisture”, the first time when the soybean comes out, soaks the soil in a timely manner, or soaks the grass in a short time; the second weed weed in the bud of the soybean, which is conducive to many branches and growing roots; and the third before the soybean gras, which facilitates the transfer of the soil, and meets the need for reproductive growth, of course, when the soil is sequestered, when it is done in the morning or evening, the soil is wet point, which does not break the roots。
In conclusion, soybeans are the country's main cash crop, rich in nutrients and diverse methods of eating, and because of its plentiful nature and inappropriate cultivation, they are not harvestable
