What to Do About Severe Soybean Lodging? A Detailed Guide to Practical Remedies
What measures can increase soybean yield? The more detailed the answer, the better. To increase soybean yield, you can use the following methods: 1. Thinning: On the basis of full emergence, thin the seedlings when the two opposite unifoliate leaves have unfolded, which generally increases yield by 10-20%. 2. Seedling pressing: When the first trifoliate leaf of some soybean seedlings has unfolded, choose a sunny...
Many of the soybeans planted this year have lodged. What should I do?Under conditions of high water and fertilizer and dense planting, soybeans tend to grow excessively and lodge, reducing yield. Early thinning, early cultivation, and reasonable water and fertilizer management are very effective, but those are matters to pay attention to during the vigorous seedling growth stage. If the above three points were not attended to during the seedling stage, preventing lodging at the pod-setting stage becomes even more important. The experience in preventing lodging is described below.
Control method: By the end of the first fu period, the plants had grown to more than 1 m tall, and some had already begun to lodge. At this time, continuous rainy weather happened to set in, and the bean plants kept growing vigorously. According to the theory of "apical dominance" in crop growth, the tips were cut off by 10 cm--20 cm. After seven or eight days, although strong wind and rain were encountered again, very few plants lodged. After another period of observation, although 2--3 flower clusters had been removed when the tips were cut, at the places 10 cm--15 cm slightly above the ground where there had originally been no flower clusters, 4--6 flower clusters began to emerge, and many flower buds also grew densely on the other branches. The "gain" here greatly exceeded the "loss" from cutting the tips.
