A Detailed Guide to Soybean Planting Methods and Planting Time

Soybean is a type of legume and the most primitive form of beans. Soybeans are widely used around us, and many things are made from soybeans as a raw material, making them very popular in the market. Now Qinnong Net is here to teach everyone how to grow soybeans and tell you what time is suitable for planting soybeans.

Planting Time

The planting time of soybeans is related to the region and climate. Different regions may differ by one or two months in planting time. The best planting time for soybeans is June every year, but in northern China it is a little earlier, generally starting gradually in April and May, while in southern China planting only starts in May and June. Later a new variety appeared called August Yellow, which means soybeans that only start being planted in August, so it is called August Yellow.

Planting Methods

1. Land preparation and fertilization

Soybeans have strong adaptability and can be planted in any kind of soil. In rural areas, many people do not even plow the land and simply make a hole every certain distance for sowing, which shows that they are quite easy to grow. But if you want high yield and high quality soybeans, we still have to follow the rules step by step. First we need to prepare the land, and when preparing the land we should plow as deep as possible, because the biggest enemy of soybeans is field mice, so this can prevent field mice; at least during land preparation some hidden field mice can be dug out. Soybeans do not need many nutrients, so when preparing the land it is enough to spread an appropriate amount of farmyard manure as base fertilizer.

2. Sowing and raising seedlings

There are two sowing methods for soybeans: direct seeding and transplanting. Direct seeding is just as mentioned above, making holes and sowing at a spacing of 30 to 50 cm per plant. For transplanting, we first need to raise seedlings in a seedbed. Before sowing, water the seedbed, then sow the seeds, cover the seeds with soil, and wait for them to sprout. When the bean seedlings grow to 4 or 5 cm, they can be transplanted, and the transplanting spacing is the same as that for direct seeding.

3. Field management

After planting, water the field roughly once, trying to water every plant, then one week later thin or fill in the seedlings in the field to ensure uniform seedlings and complete establishment. After that, within 5 to 7 days, carry out one intertillage, weeding and fertilization for the soybeans, and water once at the same time. This fertilization generally uses a mixture of compound fertilizer and urea. The second fertilization should wait until the soybeans flower and form pods. At this time the growth of the soybeans needs a certain amount of nutrients, and in order to make the pods plump, a little potassium fertilizer and phosphate fertilizer can be applied. Then you can wait for the fruit to mature.

4. Disease prevention

The period when soybeans are most likely to show disease symptoms is the time of flowering and pod formation, so in order not to reduce yield, we carry out protective measures to preserve flowers and pods, generally spraying with dimethoate emulsion.

5. Timely harvest

The maturation time of soybeans is not uniform, so special attention must be paid during harvest. Generally, when most of the pods on the bean plants gradually turn yellow-green, and when you touch them with your hand they are relatively hard rather than flat or crumbling at a touch, they can be harvested. After harvesting, they should be dried in the sun, and finally threshed. After threshing there will be a lot of debris; after clearing out the debris, they can be packed.
