The latest how to improve the fruit setting rate of colored pepper

Colored pepper often encounters the problem of difficult fruit setting rate, flower and fruit dropping culture, resulting in imbalance between vegetative growth and reproductive growth, vigorous plant growth, seriously reducing yield. Many farmers think that water control and fertilizer control can control prosperity, but the result is that the plants become more and more prosperous, and it is more and more difficult to set fruit. So how to improve the fruit setting rate of colored pepper? Let's take a look at it together with Xiaobian.

1. Cooling and ventilation

When the temperature is higher than 32 degrees, it will cause flowers and fruits to fall, which will seriously affect the fruit setting rate of color pepper. Therefore, at noon of high temperature, it is necessary to strengthen the ventilation, cover the sunshade net at the same time, or spray to reduce the temperature, so as to reduce flowers and fruits, and improve the fruit setting rate to a certain extent.

2. Adjust humidity

Humidity is also important for pollination and fertilization of color pepper. Generally speaking, the suitable air humidity for color pepper is about 70%-80%. In the peak period of flowering and fruit setting, too low or too high humidity will affect normal pollination and fertilization. Therefore, when the humidity is too low, you can spray water on the leaves with a sprayer to increase the air humidity; if the humidity is too high, ventilation and humidity are needed.

3. Reasonable fertilization

Boron and phosphorus elements play an important role in promoting flower bud differentiation and improving fruit setting rate, so boron fertilizer can be sprayed on leaves with 600 times solution of borax or 1200 times solution of Sule boron at the early stage of flowering and fruit setting. Potassium fertilizer can improve drought resistance and heat resistance of plants. In addition, calcium fertilizer can be added at the peak of fruiting period, and the concentration is about 0.5%. Calcium nitrate can also be applied 5~8 kg per mu with water. It can not only enhance plant resistance, improve pollination performance, but also improve fruit quality and prevent physiological diseases such as umbilicus rot, sunburn and bud blight.

4. Application of growth regulators

When the plants appeared excessive growth, spraying 750 times of Zhuzhuang Su and 30ppm of naphthylacetic acid on the leaves could control it, or spraying 800~1000 times of Aiduoshou solution could promote the vegetative growth to reproductive growth. In the early stage after planting, it is necessary to strengthen fertilizer and water management, so that when the eggplant plants grow excessively and do not set fruit, they can be irrigated in time or applied with fruit or fruit, which can obviously enhance the natural fruit setting rate of the plants.

5. Prevention and control of pests and diseases

Diseases and insect pests can also cause difficulty in fruit setting of color pepper, so timely spraying is needed to control them. Beta-cypermethrin, imidacloprid and other pesticides can be used to control tobacco budworm, cotton bollworm, aphid, red spider and other pests. The common diseases are virus disease, anthracnose, soft rot, etc., after discovery, we should promptly prescribe the right medicine.
