What if soybeans have a lot of lodging?

If you do not pay attention to the above three points in the seedling stage, it is even more important to prevent lodging in the fruit period. The following is the experience of lodging prevention. Prevention and control methods: grow to more than 1 meter high at the end of the initial incubation, and some have seen lodging. At this time, it was a rainy day, and the bean plant continued to grow sharply. According to the theory of "top advantage" of crop growth, the spire was cut off from 10 cm to 20 cm. After seven or eight days, although there was a heavy wind and rain, there was very little lodging. After a period of time, it was observed that although 2-3 inflorescences were removed when the head was cut off, 4-6 inflorescences began to appear in the place where there was no inflorescence 10 cm-15 cm above the ground, and many flower buds grew densely on other branches. The "gain" here is much more than the "loss" of cutting off the head. Click to see more soybean planting techniques click to see more food crop planting techniques
