The "three falling" of pepper refers to falling flowers, fallen leaves, and falling fruits. There are many reasons for this happening. There are mainly unsuitable environmental conditions, such as low temperature, insufficient nutrient soil, weak light, lack of pepper, pests and so on. Pepper is a crop that likes water but is afraid of water, but it is fat and fat, so it is necessary to consider whether the water and fertilizer are too much or too little. At the beginning of the pepper, there are flower buds buds, the plants fall, the fruit stems turn yellow and fall off, and fall in the middle and late growth stages, causing severe production loss.
First, the temperature effect
When the local temperature was lower than 18 °C, the root function of pepper began to decrease. The local temperature was lower than 8 °C, the root system stopped growing, and the plant stopped growing. When the temperature is lower than 15 °C, the pollination is affected. Although it can bloom, the pollen tube cannot extend normally, and the pollination cannot be completed, causing the flower to fall. When the local temperature is higher than 30 °C, the root system will be injured and cause falling flowers. When the temperature is higher than 35 ° C, it is not possible to pollinate.
Second, the impact of light
During the growth of the pepper, the need for illumination is met. If you encounter continuous cloudy days, insufficient light will affect light and effect, as well as falling flowers.
Third, the impact of deficiency
1. Nitrogen deficiency, the plants are short, and the leaves are yellow and fall off.
2, phosphorus deficiency, plant growth is slow, the leaves are dark green, the tip of the leaves is black and fall off.
3, lack of potassium, the leaves turn yellow and gradually expand the range, and eventually dry.
4, lack of calcium, the initial flowering period of the top leaves gradually yellowing, the growth point and the vicinity of the dead, the lower part of the fruit brown rot, which is the umbilical rot.
5, zinc deficiency, slow growth at the top, the leaves produce many leaves with small deformed leaves, brown spots, and the leaves will be yellow or fall off in a short time.
Fourth, the impact of pests and diseases
Pay attention to the prevention and control of pests and diseases, such as anthrax, bacterial leaf spot and mites such as red spider.
For the "three falling" of peppers that occur during the growing season, it is first necessary to find out the main causes of the disease, which are physiological reasons, and can be controlled by strengthening management. Severely exposed hot peppers should be drained in time to prevent damage. If the flowers are caused by drought and fallen leaves, it is necessary to timely irrigate and increase the plant to ensure the normal growth of the plants. Because the density is too large, the light is insufficient, the density should be adjusted, the weak plants should be removed, and the plants should be properly planted to facilitate ventilation and light transmission. If it is a pathological cause, the type of the disease should be determined according to the symptoms of the disease, and the degree of the disease should be ascertained in order to prevent and treat the disease.
