How are soybeans grown? What are the steps?

The planting time of soybean varies according to the weather, and it is generally divided into spring sowing and summer sowing. Spring sowing is carried out around Tomb-Sweeping Day, and the harvest period is September (August of the lunar calendar). Sow the wheat in summer after harvest, and harvest it from late September to mid-10. In addition, there is another kind of soybean in the northeast, which is sown later, but the harvest time has nothing to do with it. In northern China, spring soybeans are sown from April to May, yellow summer soybeans are sown in June after wheat harvest, southern summer soybeans are generally sown from May to early June, and autumn soybeans are sown from late July to early August.

Second, soybean planting technology

1, soil preparation and fertilization

Soybean is very adaptable and can be planted anywhere. Moreover, in rural areas, many people don't even turn over the land, so they drill a hole at an equal distance to sow, which shows that it is still quite good to feed. So if we want high-yield and high-quality soybeans, we still have to follow the rules step by step. First of all, prepare the soil. Dig as deep as possible when preparing soil, because the biggest enemy of soybean is voles, which can prevent voles, and at least dig out some hidden voles when preparing soil. Soybeans don't need many nutrients, so just sprinkle some farmyard manure as base fertilizer when preparing soil.

2. Sowing and raising seedlings

There are two ways to sow soybeans: direct seeding and transplanting. Direct seeding means drilling holes at intervals of 30-50 cm for each plant. For transplantation, we should first raise seedlings on the seedbed, wet the seedbed before sowing, then sow, cover the seeds with it and wait for germination. When the bean seedlings grow to four or five centimeters, they can be transplanted, and the interval between transplanting is the same as that between direct seeding.

3. Tian Tuan management

After planting, water the field roughly once, and water each plant as much as possible. Then, after one week, the field is thinned or replanted to ensure that the seedlings are neat and complete the planting. After five to seven days, soybeans should be weeded and fertilized once and watered at the same time. This fertilization is generally a mixture of compound fertilizer and urea. The second fertilization should wait until the soybean blooms and pods. At this time, the growth of soybean needs certain nutrients, and at the same time, in order to make the pods full, a little potassium fertilizer and phosphorus fertilizer can be added. Then you can wait for the fruit to ripen.

4. Disease prevention

The period when soybeans are most prone to symptoms is when they bloom and pod, so in order not to reduce the yield, we will take protective measures to protect soybeans from flowering and pod, and generally spray dimethoate milk.

5, timely harvesting

The maturity time of soybeans will be different, so special attention should be paid to harvesting. Generally, most of the pods on bean seedlings will turn yellow-green. At the same time, you can also harvest when you touch it hard with your hands, so it won't be flat when you touch it, and it will break when you touch it. After harvesting, it should be dried and finally threshed. There will be a lot of sundries after threshing, which can be cleaned and packed.

Soybean is generally divided into spring sowing and summer sowing. Spring soybeans in the north are generally sown in April-May, summer soybeans in the south are generally sown in May-early June, and autumn soybeans are generally sown in late July-early August.
