The first point is that fertilization is unreasonable during planting. It may be because the nitrogen content of chemical fertilizer is relatively high during use, which leads to the overall imbalance of nutrition. Part of potassium and phosphorus are relatively lacking, and phosphorus is rarely transformed in the soil, resulting in overall deficiency, so trace elements are not replenished in time after consumption. The whole plant will not develop well, resulting in the phenomenon of falling flowers.
The second reason may be that there are too many watering times. Vegetable farmers will think that as long as they water more, it will grow fast and the yield will definitely increase. Therefore, they often water a lot and water it many times, resulting in serious water accumulation in the soil. The water needed by the root system can not be absorbed in time, and the nutrition is mainly stem and leaf growth, so the overall differentiation is not very good, which will lead to flowering.
Therefore, we must water it according to the overall situation, and we must not flood it indiscriminately. When watering, we should combine various factors, and we must choose a sunny morning. We must never water it in the cold season or early morning or evening, which will cause the whole water to accumulate in the soil and cannot be absorbed in time. More importantly, we mainly pay attention to the appearance of pepper. It is best not to water the flowers temporarily before and after they bloom in large numbers, and then start watering when the flowers have withered. After that, it must be ventilated in time to reduce the humidity in the shed and prevent some diseases.
The third point is that the temperature difference between day and night is small. In fact, pepper is a kind of mild vegetable. But it can't grow in low or high temperature environment. When flowering and fruiting, the temperature should be 20 ~ 27℃ during the day and below 20℃ at night. If the temperature is too high or too low, the whole plant will be stunted, and the phenomenon of flowering due to fertilization cannot be carried out. If the temperature is too high at night, it will lead to excess of the whole plant and inhibit its growth.
The fourth point is the lack of light. If you cover plants with some old films in some cool places, when cold and warm air meet, there will be many cloudy days, insufficient light and a lot of dust floating in the air. In addition, some vegetable farmers are used to uncovering the straw cover late, and the internal light has been insufficient, which will lead to the decrease of photosynthetic effect, yield and even flower drop.
Therefore, there are many reasons for the phenomenon of fruit drop. It is not groundless, so we should take some remedial measures in time, such as proper watering and fertilization. If she grows too vigorously, we can reduce fertilization and control it in time, and we can't ignore the adjustment of temperature. If it is unreasonable, it will cause the destruction of the whole plant, and in a certain period of time, it will be ventilated and transparent to ensure that its lighting time is available.
In fact, one of the most effective methods is to use the adjustment of branches to increase its seed setting rate. In fact, in the process of planting the whole plant, it is not his own growth, but also our artificial cultivation and adjustment. If you see that its growth is not very good, you must make some adjustments in time to get it back on track in time and let her continue to grow healthily. If left unchecked and left to its own devices, it will become more and more biased in many cases, and there will be no good returns in the end.
