Prevention and Control measures of abnormal Fruit of vegetable Pepper
There are many varieties of chili peppers, and vegetable peppers are transplanted with eggplant, and many friends often use greenhouse technology to cultivate them in winter and spring, but because of the special situation this year, vegetable farmers are a little lax in their management, and when they wait for fruit setting, they find that many vegetable peppers are unable to sit on the fruit. even if the fruit is set, it is a deformed fruit. So how to prevent and cure this situation? Let's get to know it with the editor.
1. Temperature control at flowering stage
After the vegetable pepper sits on the fruit, pay attention to the temperature should not be too low, when the temperature in the shed is more than 35 degrees or 32 degrees for two hours, then the pepper will appear the phenomenon of poor pollination or fertilization. The abnormal fruit in autumn is mainly caused by high temperature, and this kind of symptom also occurs after fruit setting in spring. Often, the fruit is like a peach, and there are no well-developed seeds inside the fruit. Therefore, it is necessary to try to avoid the low temperature or ground temperature in the greenhouse, which affects the normal fruit setting of vegetable pepper. before and after fruit setting in spring, compound fertilizer and biological bacterial fertilizer can be applied to increase the fruit setting rate.
2. Balanced fertilization
Vegetable pepper in the lack of elements such as boron and calcium will choose abnormal fruit phenomenon, or seed development is not complete, so in addition to soil fertilization, but also need to pay attention to foliar fertilizer, often spraying foliar fertilizer containing elements such as boron and calcium, can effectively promote vegetable pepper fruit. Balanced fertilization, reduce the amount of nitrogen fertilizer as far as possible, and increase the application of potassium fertilizer, such as potassium dihydrogen phosphate and potassium sulfate compound fertilizer, is beneficial to fruit setting.
3. Adjust the growth trend
The plant growth of vegetable pepper will also have a certain effect on fruit setting, such as the vegetative growth of the plant is too late, resulting in excessive growth of the plant, the probability of abnormal fruit will be increased, and the growth can be adjusted by spraying growth regulators or pruning and branching to promote fruit setting. If the vegetable pepper itself can not sit still fruit, nutrients will be absorbed by the plant, resulting in plant growth, and then can be sprayed Zhuangzhuangsu and Dwarf Zhuangsu to inhibit plant growth. When spraying, it is necessary to spray in the sunny day and evening, and the temperature control is mainly to control the night temperature in the early stage to avoid vegetative growth too late, and the lack of reproductive growth affects the fruit setting rate.
4. Spraying naphthylacetic acid
It can also be sprayed with naphthylacetic acid every 7-10 days for 4-5 times, which can significantly improve the fruit setting rate, promote fruit growth, and increase the number of fruit and the weight of single fruit.
The above is the introduction of vegetable pepper abnormal fruit prevention and control measures, hope to help you, want to know more related knowledge, please pay attention to us.
