How to plant soybeans

Soybean is a leguminous soybean, which belongs to the genus Panicum and originated in China. It is cultivated all over China and all over the world. As one of the important food crops in China, it has been cultivated for 5000 years. It is most commonly used for making various bean products, extracting soybean oil, brewing soy sauce and extracting protein.

Soybean likes temperature. Seeds germinate at 10 ~ 12℃, and the optimum temperature is 15 ~ 20℃. The optimum temperature for growth is 20 ~ 25℃, and the optimum temperature for flowering and pod setting is 20 ~ 28℃. Podding is delayed at low temperature, and it cannot bloom below 14℃, and the temperature is too high. Seed germination needs more water, and the soil water content should be 70 ~ 80% at flowering stage, otherwise it will increase the rate of bud loss. The amount of fertilizer absorbed by soybean before flowering is less than 15% of the total absorption, while the flowering and pod-setting period accounts for more than 80% of the total absorption.

When planting soybeans, the seedbed should be arranged first to ensure looseness, fertility and good air permeability, and appropriate base fertilizer should be applied. After the treatment, sprinkle the seeds on it, and pay attention to controlling the spacing between plants, with the spacing between each plant being 30-50 cm. After planting, cover the soil and wait for germination. When the seedlings grow to 4-5 cm high, they can be planted. During the later management period, we should pay attention to the environment provided at ordinary times, which is suitable and rich in fertilizer and water, so that the output will be higher.

Under normal circumstances, soybean is sown with fertilizer seeds separately, and the amount of fertilizer can be adjusted at 4 ~ 5 cm below the seed side. When diammonium phosphate is applied more than 20 kg per mu, it can be applied in layers. The upper layer is 5-7cm deep, and the fertilization amount accounts for 1/3, the bottom layer is 10- 16cm, and the fertilization amount accounts for 2/3. Or after the previous crop is harvested, spread the fermented organic fertilizer evenly on the ground, then rake the fertilizer into the soil with a rake, fully mix the manure with the soil, and then dig it deeply, and the raked bottle is finely ridged, or plant soybeans flat.
