Soybeans are very common in our daily life, and soybeans are also the main raw material for making all kinds of soybean products. Therefore, soybean still has a large planting area in our country. When growing soybeans, fertilization is very important if you want to increase the yield. So what are the fertilization techniques for planting soybeans? Today, the editor will give you a brief introduction. Let's take a look at it.

1. Characteristics of fertilizer requirement

In the flowering and pod stage of soybean, it is a peak period of dry matter accumulation of soybean. At this time, the absorption of nitrogen, phosphorus, potassium and other nutrients by soybean reached its peak. Among them, the demand for nitrogen element of soybean is very large, although the root nodule of soybean can fix nitrogen, but its nitrogen demand is still very large. However, because of its own nitrogen fixation, it can be applied less. In addition, attention should also be paid to the supplement of calcium and sulfur. Reasonable supplement of calcium and sulfur can effectively improve the yield and quality of soybean, so we should pay more attention to it.

2. Principles of fertilization

When fertilizing soybeans, we should pay attention to the reasonable collocation of nitrogen, phosphorus, potassium and other fertilizers. The amount of nitrogen fertilizer should be applied less, and the early flowering stage should be the key point of topdressing. At the same time, we should also pay attention to the supplement of calcium, sulfur and other trace elements. It can be carried out by means of foliar fertilization and seed dressing with micro-fertilizer. It is best to use rhizobium agents to mix seeds to improve the nodulation efficiency of soybean plants. At the same time, we should also pay attention to the relationship between soybean continuous cropping and fertilization, if the repeated cropping is serious and can not be avoided, then we can appropriately apply some nitrogen fertilizer, or choose a general compound fertilizer. To prevent the decline of nitrogen fixation ability of soybean.

3. Strengthen the management

When planting soybeans, we should combine deep ploughing and soil preparation with the application of organic fertilizer. If it is spring soybeans, it should be ploughed about 20cm after the previous autumn harvest, and then sown in spring. On the other hand, summer soybeans can be ploughed deeply before wheat planting and shallow ploughing before planting beans. At the same time, we have to use different tillage and sowing methods according to the local climate, soil environment and mechanical conditions.

In addition to mechanized stratified fertilization, we should pay attention to topdressing appropriate amount of nitrogen fertilizer during the early flowering stage of soybean. In the soybean seedling stage, it is necessary to do a good job of ploughing and weeding. At the same time, in the flower and pod period, if you encounter drought, then you should also pay attention to watering. Through agricultural, biological and chemical and other control measures to do a good job in the prevention and control of diseases and insect pests to ensure the normal growth of soybean.

The above is the brief introduction of soybean fertilization technology. That's all for today's introduction. This article is for reference only. I hope it can help you all.
