Soybean has a long history of cultivation in China. It originated in China, and the edamame in Hutang Village, Lixian County, Pingxiang City, Jiangxi Province, China is famous all over the world. There are mainly early-maturing, middle-maturing and late-maturing varieties of soybeans. The early-maturing cultivation time is from late February to early March, and the middle-maturing varieties are sown from late April to mid-May and harvested from July to August. In autumn, the late-maturing varieties will be directly broadcast from June to July, and the harvest will be -65438+ 10 in late September. The autumn sowing in South China can be delayed by one month.

Growth cycle of soybean

Sow summer soybeans from late April to mid-April, grow for 3 months, and harvest in July and August. When planting, the seeds should be soaked first, and the seeds will germinate and grow faster after absorbing enough water. At first, only cotyledons grew. After absorbing light, water and nutrients, cotyledons will grow up slowly and grow real leaves. Once the real leaves grow, they will grow faster and will soon grow many leaves. Gradually, it will grow very tall, and in the later stage, it will blossom and bear fruit, and the fruit will grow slowly, which is what we see as edamame. From 20 10 to 20 10, the growth period of soybean needs 100 days, while the growth period of soybean needs only 60 days, so many growers will choose to plant green beans. Generally, the yield of fresh pods per mu is about 600 Jin, and the yield of one mu of land is about 700 yuan.

Cost and profit of soybean planting

1. Pay attention to transplanting early-maturing seedlings and directly plant middle-late mature seedlings. Whether it is live broadcast or transplanting, it should be timely, and the width of the border should be determined according to the customs of each region. Generally, if the groundwater is low and the drainage is good, the boundary can be wider; On the contrary, it should be narrower, but a deep ditch should be opened. 2. During the whole growth period of field management, edamame should be loosened and weeded for about 3 times in time. When the seedling height is about 30cm, loosen the soil to promote the growth of root system. Under normal circumstances, irrigation is not needed. If the temperature is very high, you can use the drain to water it twice. The main pests that harm edamame are red spider, aphid and caterpillar. We should pay attention to the prevention and control of pests and diseases.
