How to grow soybeans? Six common sayings tell the whole process of high yield of soybean!

As a cash crop, soybean is widely planted in China. There are many varieties of soybeans, such as mung beans, soybeans and black beans. They are rich in nutrition, can be processed into various bean foods, and can also extract soybean oil, brew soy sauce and extract protein. In the 1970s and 1980s, rural children would uproot soybeans and bake them directly on the fire until they were 70-80% mature. That kind of happiness is beyond the comprehension of children nowadays. How to grow soybeans?

Soybean has been cultivated in China for more than 5000 years. It was called Zizania latifolia in ancient times. Because of its rich nutrition, people call it "the king of beans" and "the meat of the field". However, soybean is also a particularly vulnerable crop. It is afraid of drought and waterlogging. If the environment is not suitable, it will not bloom and pod. So sometimes the beans in the field are bigger, but there are no beans. Today, we will use six proverbs.

First, plant soybeans for three days from summer solstice, and there are no early beans after wheat.

This proverb means that soybeans should be sown in summer to three days later. At this time, the wheat has just been harvested, and the interplanting effect between stubbles is the best, which can not only meet the growth cycle time of soybean, but also meet the temperature demand of growth. Soybean is a kind of crop that likes temperature and light. The optimum growth temperature is 20 ~ 25℃, the optimum flowering and pod setting temperature is about 27℃, and the low temperature growth is poor, and the seed germination temperature is 65438.

Second, you don't need a plow to cut wheat and grow beans. If it rains, you should seize the land.

This proverb means that you don't have to dig deep to plant soybeans, you can plant them directly. If you sow soybeans before a rain, the effect will be better, because soybean seeds are hard and have poor water absorption capacity, and the roots are weak after germination, and the organic matter in the soil is slowly absorbed. In most areas in the north, wheat is directly sown after cutting the straw and returning it to the field, which greatly reduces irrigation water, soil organic matter will not be lost, and at the same time reduces labor costs.

Third, if you want the beans to be neat, plant them on the land.

This proverb means that if you want a high emergence rate of soybeans, you must plant them lightly, because soybeans are dicotyledonous plants, and when their seeds germinate, two young leaves will appear. If the sowing is too deep, it will rise out of the ground by cotyledons after germination, and it is difficult to break through the soil layer, and eventually it will become yellow seedlings and weak seedlings. Moreover, if the sowing is too deep and the weather is hot and rainy, soybeans will rot in the soil, resulting in a serious shortage of seedlings in the field.

Four, neither thin nor thick, a _ s.

This proverb means that soybeans should be planted reasonably close and spaced a little more than one plant. One is that the distance between the thumb and forefinger of an adult is about 18 cm. Of course, we should also pay attention to the variety of soybean, and the planting density of plant type should be small. If there are few branches, the planting density of plant-type connection will be large, and at the same time, we should pay attention to the principle of "fertile land should be sparse and thin land should be dense" Generally speaking, the planting density of soybean is about 0/.5-30 thousand plants per mu/kloc-0.

Fifth, the bean field is adjusted every year, and the beans are good every year.

This proverb means that continuous cropping is forbidden in soybean planting, and it is best to rotate in paddy field and dry field if possible, so that soybean can produce high yield, because the root system of soybean will secrete organic acids, which will react with heavy metals in the soil to produce toxic substances, leading to the decline of soil fertility, and various germs and eggs lurk in the root system of soybean, which will lead to the aggravation of field diseases if rotation is not carried out. More importantly, the potassium and nitrogen elements in the soil are not enough to meet the growth of soybeans under continuous cropping.

Six, bean hoe three times, pod series.

This proverb means that when managing soybeans, you have to use a hoe three times to get high yield. In some places, the proverb is "The bean hoe jingles three times". This is because the root system of soybean is short and dense, so the soil permeability must be ensured, and weeds must be eradicated at the same time, so that soybean can grow well. Folks say that hoes have "three treasures", which are waterproof, drought-resistant and weed-proof. The first time is when the bean seedlings just come out, we should loosen the soil in time and eradicate the larvae. The second weeding is in the flower bud differentiation stage of beans, at which time weeding is beneficial to many branches and strong roots; The third time, before flowering and pod setting, hoeing is beneficial to soil nutrient transportation and meets the needs of soybean reproductive growth. Of course, when hoeing, be careful not to break the roots, and try not to break the developed roots of beans in the morning or at night when the soil is wet.

To sum up, soybean is the main cash crop in China, with rich nutrition and various eating methods. Because of delicate and improper planting, the harvest will fail. The above six proverbs tell the secret of high yield of soybean planting, which is worth collecting!
