How to improve the Fruit setting rate of Color Pepper

Color pepper often encounter the problem of difficult fruit setting rate, falling flowers and fruit culture, resulting in vegetative growth and reproductive growth imbalance, plant growth, seriously reduce the yield. Many farmers think that controlling water and fertilizer can control the growth, but the result is that the plants are 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? Come and have a look with the editor.

1. Cooling and ventilation

When the temperature is higher than 32 degrees, it will seriously affect the fruit setting rate of colored peppers, so it is necessary to strengthen the air release at noon in high temperature, cover the sunshade net at the same time, or spray to reduce the temperature, which can reduce flower and fruit drop and increase the fruit setting rate to a certain extent.

2. Control humidity

Humidity is also important for pollination and fertilization of colored peppers. Generally speaking, the appropriate air humidity for colored peppers is about 70% and 80%. During the peak period of flowering and fruit setting, the humidity is too low or too high, which will affect the normal pollination and fertilization. Therefore, when the humidity is too low, you can use a sprayer to spray water on the leaves to improve the air humidity; if the humidity is too high, ventilation is needed.

3. Rational fertilization

Boron and phosphorus play an important role in promoting flower bud differentiation and increasing fruit setting rate, so boron fertilizer can be sprayed with 600 times borax or 1200 times boron foliar at the early stage of flowering and fruit setting. The application of potassium fertilizer can improve the drought resistance and heat resistance of plants. in addition, calcium fertilizer can be increased in the peak fruiting period, with a concentration of about 0.5%, or 5 kg calcium nitrate per mu. This can not only enhance plant resistance, improve pollination performance, but also improve fruit quality and prevent physiological diseases such as navel rot, sunburn, bud blight and so on.

4. Application of growth regulators

When the overgrowth of the plant occurs, it can be controlled by foliar spraying 750x solution plus 30ppm's naphthalene acetic acid, or spraying 800mm / 1000x Aidoushou solution can promote vegetative growth to reproductive growth. In the early stage after planting, it is necessary to strengthen fertilizer and water management, so that when the plant eggplant grows but does not set fruit, timely irrigation of roots or application of fruit beier or profruit with water can significantly enhance the natural fruit setting rate of the plant.

5. prevention and control of diseases and insect pests

Diseases and insect pests can also cause difficulties in fruit setting of colored pepper, which need to be controlled by timely spraying. Cypermethrin, imidacloprid and other insecticides can be used to control tobacco pests, cotton bollworm, aphids, red spiders and other pests. The common diseases are virus disease, anthrax, soft rot and so on.

The above is how to improve the fruit setting rate of colored pepper introduction, hope to help you, want to know more related knowledge, please pay attention to us.
