Pepper is a common crop in rural areas. Some are planted in greenhouses for planting peppers, and some are farmed in the open air in their own fields. However, there is a "three falling" phenomenon during the planting process. This article will mainly talk about this issue.
From the seedling stage to the fruiting stage, the pepper grows slowly and has a long period. Observe the environment in the ground at any time, adjust the light, temperature and humidity, control the pests and viruses, pay attention to the season of fertilization and topdressing, and reduce the trunk of the early pepper. The situation where the fruit fell.
1. What is the "3 drop" phenomenon of pepper?
"3 falls" refers to the leaves, fallen flowers and fallen fruits of pepper. There are two main reasons for the "three falling": First, the environmental species is not suitable, the intensity of the light, the temperature, the humidity and the environmental factors. Second, there is a separation between the petiole or insufficient nutrient or excess, resulting in poor pollination and fertilization, resulting in "3 falls."
2. Main prevention measures:
(1) In the planting process, if it is cultivated in the open field, it can be planted in a row of about 20 cm from the pepper, because the bean leaves can shade the pepper and reduce the virus disease, which is conducive to temperature adjustment, because the field is ventilated, the bean yield is high. Also high. If it is cultivated in a greenhouse, carefully observe whether the light, temperature and humidity in the shed are suitable for the growth of pepper. Adjusting these can effectively prevent the falling and falling of the pepper.
Remove the weeds and prevent diseases such as mites and cotton bollworms. Capsicum virus disease is mainly caused by aphids, and aphids can be removed with an appropriate amount of 5% natural pyrethrin emulsifiable concentrate preparation or 0.3% neem emulsifiable concentrate preparation. After the fruit is placed on the fruit, combined with the control of cotton bollworm, spray 2 times of the appropriate amount of Bacillus thuringiensis emulsion preparation 3 to 4 days and 6 to 8 days after the egg peak; at the peak of the incubation period, the appropriate amount of 20% diflubenzuron or 50% octyl sulfide Phosphorus emulsifiable concentrate sprays against cotton bollworm.
(2) Carefully observe and maintain the soil wetness. After harvesting the pepper, do not slam the water after excessive drought or exposure. Under normal circumstances, water is poured about 5 to 7 days in the early stage, and the water is poured once every 4 to 5 days. . Watering is better in the morning on sunny days. In the hot season, it is necessary to pay attention to watering in the evening to reduce the temperature in the ground and keep the soil moist. Pay attention to drainage when it is rainy. It is best to use drip irrigation or submerged drenching to prevent the temperature from being too high. Topdressing should be based on a small number of times. Generally, when the ground fertilizer is sufficient, the door pepper can meet the basic needs before the fruit. When the door is 2 to 3 cm long, the first top dressing can be combined with watering. Urea and potassium sulfate are applied with water. In the fruiting period, depending on the plant growth and results, you can continue to apply fertilizer or decomposed organic fertilizer 1 or 2 times.
