A Detailed Tutorial on the Latest Soybean Fertilization Techniques and Methods
Soybeans are very common in our daily lives, and soybeans are also the main raw material for making various soy products. Therefore, soybeans still have a relatively large planting area in our country. When planting soybeans, if you want to increase the yield, then fertilization work is very important. So when planting soybeans, what fertilization techniques are there? Today the editor will give you a brief introduction. Let's take a look below!
1. Fertilizer requirements
During the flowering and podding stage of soybeans, this is a peak period for dry matter accumulation in soybeans. At this time, the soybean's absorption of nutrients such as nitrogen, phosphorus and potassium reaches its peak. Among them, soybeans have a very large demand for nitrogen. Although soybean root nodules can fix nitrogen, their nitrogen requirement is still very large. However, because they have nitrogen-fixing capability themselves, less can be applied. In addition, attention should also be paid to supplementing calcium and sulfur. Reasonable supplementation of calcium and sulfur can effectively improve soybean yield and quality, so everyone should pay more attention.
2. Fertilization principles
When fertilizing soybeans, we should pay attention to a reasonable combination of fertilizers such as nitrogen, phosphorus and potassium. Nitrogen fertilizer should be applied in an appropriate and small amount, with the early flowering stage as the key topdressing period. At the same time, attention should also be paid to supplementing medium and trace elements such as calcium and sulfur. Methods such as foliar fertilization and seed dressing with microelement fertilizers can be used. It is best to use rhizobium agents for mixed seed dressing to improve the nodulation efficiency of soybean plants. At the same time, attention should also be paid to the relationship between continuous soybean cropping and fertilization. If continuous cropping is severe and unavoidable, then an appropriate amount of nitrogen fertilizer can be added, or a general-purpose compound fertilizer can be selected. This prevents the decline of soybean nitrogen-fixing ability.
3. Strengthen management
When planting soybeans, we should combine deep plowing and land preparation with the application of organic fertilizer. If it is spring soybean, then after the autumn harvest of the previous crop, deep plowing should be carried out to about 20cm, and then sowing should be done in spring. For summer soybean, deep plowing can be carried out before planting wheat, and shallow plowing and rush planting can be carried out before planting soybeans. At the same time, we should also use different tillage and sowing methods according to the local climate, soil environment and mechanical conditions.
In addition to mechanized layered fertilization work, we should pay attention to applying an appropriate amount of nitrogen fertilizer at the early flowering stage of soybeans. At the soybean seedling stage, we should do a good job of intertillage, earthing up and weeding. At the same time, during the flowering and podding stage, if drought occurs, then attention should also be paid to watering work. Through various control measures such as agricultural, biological and chemical methods, do a good job in pest and disease control to ensure the normal growth of soybeans.
The above is a brief introduction to what soybean fertilization techniques there are. That's all for today's introduction. This article is for reference only, and I hope it can help everyone!
