Regulating plants, raising leaves, replenishing fertilizer and water to promote more pod setting of beans

The market of beans is good this year, and the price is still above 2 yuan per jin. Many vegetable farmers are only greedy, because many beans are very difficult to sit on pods, even if they are only defective pods, which are worthless at all. However, recently, in Dongxia Town, Qingzhou City, the author saw that the beans planted by Zhang Huaqing were uniform in length and green in color, and he picked more than 300 jin at a time. After talking with Master Zhang, the author thinks that Master Zhang's management experience is worth recommending. First of all, plant adjustment should be carried out in time. Remove the lateral branches below the first inflorescence of the main vine, that is, the lateral branches above the nodes of the first inflorescence of the main vine, leave 1-3 leaves to pick the heart, retain the inflorescence on the lateral branches, and increase the pod-bearing parts. When the main vine grows to 2-2.3 meters, the sprouting side branches at the top leave a leaf to pick the heart and seal the top, promoting the formation and development of flower buds in the lower node, preventing the main vine from being too long, winding each other between the racks, not ventilated, and not conducive to picking beans. Secondly, turn off the temperature and raise the leaves and vines. The temperature difference between day and night should be strictly checked, the bean has strong heat resistance, and the suitable growth temperature is 25 ℃ ~ 28 ℃. The suitable growth temperature of bean during flowering period should not exceed 35 ℃ in daytime and 18 ℃ at night, which enlarges the temperature difference between day and night. Therefore, it is necessary to strictly control the temperature and change the release time with the continuous change of external temperature. In addition, if there is poor ventilation and light transmission at the bottom of the plant in production, it is easy to cause flowers and pods to fall in the later stage, the lower old leaves can be cut off and the fallen leaves in the field can be removed. In addition, seize the critical period to replenish fat and water. The flowering and podding period of bean is longer, and after the first yield peak, the plant growth weakens, the flowering and pod is few, and the stubble phenomenon appears. Therefore, 1520kg compound fertilizer + 10kg calcium superphosphate + 5kg potash fertilizer should be applied 5-7 days before flowering, which can promote flowering and pod formation. In the peak period of pod growth, topdressing should be applied again, applying 15kg to 25kg compound fertilizer per mu. After the full pod stage, according to the plant growth, a certain amount of water-soluble fertilizer can be applied to prolong the harvest time and increase the yield of beans.
