Reasons for low fruit setting rate of hot pepper

Pepper is one of the common vegetables in our life. Pepper grows well and blossoms normally in the early growth stage, but it just can't sit still and the yield is low. So what is the reason for the low fruit setting rate of hot pepper? Let's take a look at the detailed introduction.

1. Poor flower bud differentiation.

The main reason for the difficulty of fruit setting in pepper is high temperature, especially when the temperature is too high at night, the respiration of the plant at night is enhanced, the accumulation of organic matter is less, and the vegetative growth takes up a lot of nutrients and inhibits the reproductive growth of the plant. In addition, when the daytime temperature exceeds 35 degrees, the flower bud differentiation of chili peppers will be affected, and many flowers will fall off every time they bloom.

Solution: the temperature accumulated in 15-30 degrees can grow normally, and the most suitable temperature for growth is 20-28 degrees. During the fruit setting period, it is necessary to control the temperature, between 18-25 degrees during the day and 15-18 degrees at night. Once the temperature exceeds 26 degrees, its fruit setting rate will decrease.

2. Overgrowth of plants

Improper management of fertilizer and water during the flowering and fruiting stage of pepper leads to exuberant vegetative growth, resulting in excessive growth of branches and leaves, which consumes a lot of nutrients of the plant, which will lead to low fruit setting rate.

Solution: in the excessive growth of plants, it is necessary to regulate the amount of chemicals to control vegetative growth and promote reproductive growth. At this time, we can spray chlorophyll, golden green garden and other growth control products to properly control the overgrowth of plants. But be careful not to spray repeatedly when spraying, so as to avoid drug damage.

3. Boron deficiency

Pepper has a certain demand for boron when setting fruit. If there is a serious lack of boron, it will have a very low fruit setting rate.

Solution: boron plays an important role in flower bud differentiation of plants. for the problem of boron deficiency, foliar fertilizer should be sprayed in time to promote flowering and fruit setting.

4. Poor pollination

When planting, because of the high humidity in the greenhouse, the pollen is sticky and can not be dispersed in time, so it will lead to poor pollination, resulting in low fruit setting rate, or poor pollination due to other reasons, which will also affect the fruit setting rate.

Solution: after the peak fruiting period of hot pepper, the branches, weak branches and diseased branches should be trimmed off in time, but not too much, so as not to reduce the fruit setting rate, and pay attention to the humidity in the greenhouse so as not to affect the pollen emission.

The above is the introduction of the reasons for the low fruit setting rate of chili peppers. I hope I can help you. If you want to know more about it, please follow us.
