The latest reasons for the overgrowth of chili and its control measures

Pepper is the most common vegetable in our life, which is planted all over the country, but the growers all know that chili peppers are prone to overgrowth. After overgrowth, the stem of pepper is thin, the leaves are hypertrophic, and then the flowers are thin and weak, without fruit, which seriously affects the yield and income, so what is the reason for the excessive growth of pepper? How to prevent and cure it? Let's get to know it.

First, the reasons for futile growth

There are many reasons for the growth of normal pepper, the temperature is too high, especially the night temperature is too high, once the night temperature is higher than 20 degrees, plant respiration increases, excessive digestion of nutrients, the phenomenon of overgrowth. Weak light, in case of continuous rain or field closure, will weaken the photosynthesis of leaves, synthetic nutrients watering, the phototropism of plants will make stems and leaves win light, resulting in the phenomenon of excessive growth. High humidity in the field or continuous rainy weather and frequent watering will also lead to excessive growth of pepper plant stems and leaves, and excessive application of nitrogen fertilizer during fertilization will also lead to plant overgrowth.

II. Prevention and control measures

1. Cultivate strong seedlings

Before planting, it is necessary to do a good job in soil preparation, fertilization, ditch drainage and other preparatory work, so that the seedlings grow in an environment with high humidity and high temperature, coupled with sufficient nutrition to make their growth strong and conducive to slow seedling growth.

2. Timely planting

When pepper seedlings grow to 5-6 pieces, they should be sprayed with daconine or amiceda every 10 days after planting to prevent diseases.

3. Ventilation and pruning

In the slow seedling to maintain a certain temperature, ventilation to reduce humidity at night temperature should not be less than 15 degrees, day and night ventilation, in the summer high temperature period, you can use the shade net to cool down. In the middle and later stage of plant growth, proper pruning and leafing should be done to increase the permeability between plants and avoid overgrowth in the field.

4. Control mode

In the case of sufficient base fertilizer, there is generally no need to water and fertilize before flowering and fruiting, especially when plastic film mulching is adopted, watering and fertilizing according to the situation after fruit setting. However, it is necessary to control the amount of nitrogen fertilizer, so as to avoid excessive application. In the flowering and fruiting period, it is necessary to coordinate the vegetative growth and reproductive growth of the plant, the overgrowth of vegetative growth affects the normal fruit setting, and growth regulators are used to control the vegetative growth.

5. Remedial measures

For the overgrown plants, it can be sprayed with zhuangsu or dwarf to control the growth, and for the overgrown plants that lead to serious flower and fruit drop, naphthalene acetic acid solution can be sprayed.

The above is the introduction of the reasons for the overgrowth of chili and the control measures. I hope I can help you. If you want to know more about it, please pay attention to us.
