The decrease in fruit setting rate and the increase in the number of deformed fruit are the problems often encountered in the production of summer fruits and vegetables, which seriously affects the yield and quality of vegetables. Recently, many vegetable farmers have called to ask about this issue, hoping to provide a good way to stop this. Here, according to the current climate, the author will analyze the reasons for the following: First, high temperature. This is the culprit that caused the tomatoes to fall. In the cultivation of summer vegetables, especially at noon, the high temperature of 32 degrees Celsius is often present. Everyone knows that low temperatures in early winter and early spring are an important factor affecting the fruit setting rate of vegetables, and the same high temperature also seriously affects the fruit setting rate of vegetables. The temperature is too high and the adhesion between pollen and stigma is reduced. At the same time, the pollen germination rate and the pollen tube's elongation rate are seriously affected, which leads to poor pollination and fertilization, and the fertilization process is disordered. As a result, a large number of flowers and fruit fall off and produce a large number of malformed fruits. Therefore, it is necessary to strengthen ventilation at noon at high temperatures and use shade nets to cover cultivation. Second, air drying. Appropriate air humidity is also very important for normal fertilization. In general, suitable air humidity is 70% to 80%. Especially during the flowering and fruit setting period, to keep the dry ground between the ground, sprayer can be used to spray water to increase air humidity. Third, the lack of certain nutrients. Boron and phosphorus play an important role in promoting the differentiation of flower buds and improving the fruit setting rate. In flowering and fruit setting period, borax and potassium dihydrogen phosphate solution can be sprayed on the leaves. It is important to increase calcium fertilizer during the fruitful period to enhance plant resistance, improve pollination performance, improve fruit quality, and prevent physiological diseases such as umbilical rot, sunburn, and bud blight. In the hot and dry season, increasing potash fertilizer can improve plant resistance to drought and heat. Fourth, nurturing strong seedlings. It is important to cultivate age-appropriate seedlings to enhance plant resistance and increase fruit setting rate. The flower bud differentiation at the seedbed stage directly determines the fruit setting rate of the first to second Pang Guo after planting. Now is in the nursery period, to shading nets, insect nets coverage, lower seedbed temperature, in the middle and late can be spraying potassium dihydrogen phosphate solution, depending on the plant growth decided to spray foliar booster prime, to control plant leggy. Fifth, plant leggy. High temperature and long days produce a large amount of gibberellin at the growing point of the plant. It is easy to make the internodes grow too long and the nutrient grows excessively, resulting in falling fruit. In addition to control the amount of nitrogen fertilizer, increase phosphorus and potassium fertilizer.
