Will soybean lodging affect production?
Basically, the lodging of soybean has a great influence on the yield. Once the soybeans fall down, the yield is difficult, the grains are small, the grains are small, and some grains are the same as the [chili seeds". The yield is severely reduced. Under normal circumstances, the yield can be reduced by 20-30%. It can reach more than 50%, or even more, so it is necessary to prevent lodging in production and avoid losses.
What are the reasons for soybean lodging?
To solve the problem of soybean lodging, we must first understand the cause of the soybeans falling.
1. If the planting density is too large, it will cause lodging. Generally, the common standard ridge (65-70 cm), the mu seedlings should be controlled from 1.8 to 2 million, and the 110 cm large ridge should be controlled between 2.1 and 23,000.
2. Excessive application of nitrogen fertilizer, due to the nitrogen fixation effect of soybean rhizobium, it is necessary to re-apply phosphorus and potassium fertilizer in fertilization, lightly apply nitrogen fertilizer, and apply urea about 5 to 6 kg according to the ground force.
3. The reason for the variety, the lodging resistance and the variety have a certain relationship, which is a specific trait of the variety, and the lodging resistance of different varieties varies greatly.
Soybean lodging response
1. To maintain a reasonable cultivation density, a reasonable cultivation density should be determined according to soil fertility, variety characteristics, and local accumulated temperature.
2. Reasonably balance fertilization, control the total amount of nitrogen fertilizer, prevent prolonged, and cause lodging.
3. According to the reasonable growth of soybeans, once the soybeans show signs of prosperous growth, spray paclobutrazol, chlormequat and potassium dihydrogen phosphate to achieve the effect of controlling the rods and protecting the pods.
4. Choose high-quality varieties that are strong, drought-resistant and lodging-resistant.
In general, there are more than one cause of soybean lodging. Therefore, everyone should pay special attention to the planting and management process of soybeans. The above contents are for reference only. Farmers with better experience are welcome to continue sharing!
