First of all, according to growth needs, a reasonable watering. The roots of legumes are very sensitive to moisture and prefer to grow in relatively moist soils, but they are particularly vulnerable to flooding. Especially during flowering, the accumulation of water in the soil will cause pollen reduction, affect pollination, reduce the occurrence of scab, and soil. Water accumulation for a long time can easily result in falling flowers and falling down. Therefore, when watering, pay attention to the amount of water, mainly pouring small water, and avoid flooding.
In the seedling stage, the beans should strictly control the amount of water. After soaking in the bottom water and easing the seedling water, try not to water or water. The reason for controlling the amount of water is that the water content in the soil affects the legume blossoms. When the first inflorescence is seated, it can increase the amount of watering and promote the growth of soybean meal, and at the same time remind farmers to pay attention to reduce the watering after entering the fruit period to prevent flowering and falling down.
Again, pay attention to fertilizer types and promote rooting. In order to increase the root activity, the rooting alginic acid, chitin, and humic acid-based fertilizers should be used in the winter cold season to promote the growth of capillary roots. To minimize the use of compound fertilizers, all-water-soluble fertilizers can be used instead of compound fertilizers to provide nutrition for the growth of beans.
Finally, control the amount of fertilizer used and make reasonable supplements. Beans based on the application of base fertilizer, generally do not need to top dressing after flowering and scabbing, when the first pods sit, to increase the top dressing, and when the beans into the fruit period, generally no longer a lot top dressing. Moreover, when top-dressing, it should pay attention to the amount, should be subject to a small number of multiple applications, conducive to the absorption of the root system.
