On March 23, the reporter went to the shed of a vegetable farmer on the ancient city street of Shouguang City and found that there was no phenomenon of cowpea trees growing on the phone before the vegetable growers. However, the flowers were rare and they were easy to fall off. What's going on here? In order to answer the doubts of the vegetable farmers, Yuan Guojie, a reporter of the Northern Vegetable News explained to them little by little: the lack of flowers, and the difficulty in flowering and flowering are due to poor flower differentiation. Why does the flower not differentiate well? This will be from several aspects: First of all, when we entered the greenhouse, we felt that the shed had poor insulation. In the early days when flower buds differentiated, they were at a low temperature period. In addition, the greenhouse had poor insulation, and the temperature in the greenhouse was too low, directly affecting the normal differentiation of flower buds, or incomplete flower development and infertility flowers. Flowers could not be fertilized and fell off. Second, the soil and air in the shed were too dry, the pollen was prematurely decayed, and the stigma was dry, which was also the reason why they couldn't stand flowers. According to the farmers, after pouring water from the planting plant, they did not water the plant for a long time. Recently, they were considering filling the water once. The reporter suggested that he should not apply fertilizer temporarily, but only pour water. Because at this time the kidney beans are not prosperous, but they are not weak, and they are prone to cause prolonged growth and weaken flower bud differentiation. Moreover, the pods of this shed were too densely planted and the shade between the rows was quite serious. The reporter suggested that appropriate sparse leaf treatment should be done. In the future planting, proper close planting should be taken care of. In the case of a constant plant spacing of 40 cm, two seedlings per hole can be changed to two seedlings at each point, or the spacing of the changed plants is 45 cm. The planting is too dense, and the lack of light can cause the nutrient deficiency of the cowpea calyx and fall off during the developmental process. In short, to improve the situation in which cowpeas spend less time and spend more time sitting on flowers, in addition to reasonable field operations, some molybdenum-containing boron-containing agents can also be sprayed.
