Causes of overgrowth of chili and its control measures

Chili is the most common vegetable in our life. It is planted all over the country, but people who grow it know that chili is easy to grow. After excessive growth, the pepper stems are thin and weak, the leaves are plump, the flowers are thin and weak, and the fruit is not produced, which seriously affects the yield and income. What is the cause of excessive growth of pepper? How to prevent it? Let's get to know each other.

I. Reasons for excess growth

There are many reasons for normal pepper excess growth, especially if the temperature is too high at night, once the night temperature is higher than 20 degrees, the respiration of the plant increases, excessive digestion and nutrition occur. Light is weak, in case of continuous rain or closed field, photosynthesis of leaves will be weakened, synthetic nutrients will be watered, and the phototropism of plants will make stems and leaves shine, thus appearing excessive growth phenomenon. Field humidity or continuous rainy weather and watering too often, will also cause pepper plants stem and leaf excessive growth, fertilization excessive nitrogen application, will also lead to excessive plant growth.

II. Prevention and control measures

1. Cultivate strong seedlings

Before planting, preparation work such as soil preparation, fertilization, ditching and drainage should be done well, so that seedlings grow in an environment with higher humidity and higher temperature, and sufficient nutrition can make them grow strong and conducive to slow seedlings.

2. Timely planting

When pepper seedlings grow to 5-6 pieces, they can be planted. After planting, they should spray Daconin or Amisida every 10 days to prevent diseases.

3. Ventilation pruning

After slow seedling, keep a certain temperature, ventilate to reduce humidity, night temperature shall not be lower than 15 degrees, day and night ventilation, in the summer high temperature period, you can use shade net to shade and cool down. During the middle and later stages of plant growth, proper pruning and leaf beating should be carried out to increase the permeability between plants and avoid overgrowth due to closed field.

4. Control mode

In the case of sufficient base fertilizer, there is generally no need to water and fertilize before flowering, especially if the plastic film mulching cultivation method is adopted, and watering and fertilizing are carried out after fruiting. However, the amount of nitrogen fertilizer applied should be controlled to avoid excessive normal growth. In flowering and fruiting stage, the vegetative growth and reproductive growth of plants should be coordinated. The over-growth of full vegetative growth affects normal fruit setting. At the same time, growth regulators should be used to control vegetative growth.

5. Remedy measures

For the plants that have grown too long, you can spray auxin or chlormequat to control prosperity. For the plants that have grown too long and lead to serious flower and fruit drop, you can spray naphthylacetic acid solution.

The above is an introduction to the causes and control measures of pepper excess growth. I hope it can help you. If you want to know more about it, please pay attention to us.
