What are the reasons for low fruit-setting rate in peppers
Pepper is one of the common vegetables in our daily lives. In the early growth stage, peppers grow well and bloom normally, but they just cannot hold their fruit, resulting in low yield. So what are the reasons for the low fruit-setting rate in peppers? Let's take a look at the detailed introduction.
1. Poor flower bud differentiation
The main reason why peppers have difficulty setting fruit is high temperature, especially when the nighttime temperature is too high, the plant's nighttime respiration is strengthened, less organic matter accumulates, and vegetative growth grabs a large amount of nutrients, inhibiting the plant's reproductive growth. In addition, when the daytime temperature exceeds 35°C, the flower bud differentiation of peppers will be affected, and many flowers will drop not long after blooming.
Solution: Peppers can grow normally at accumulated temperatures of 15-30°C, and the most suitable growth temperature is 20-28°C. During the fruit-setting period, the temperature must be well controlled, between 18-25°C during the day and between 15-18°C at night. Once the temperature exceeds 26°C, its fruit-setting rate will decline progressively.
2. Excessive vegetative growth of the plant
Improper fertilizer and water management during the flowering and fruiting period of peppers leads to vigorous vegetative growth, causing excessive growth of branches and leaves, which consumes a large amount of nutrients from the plant, thus resulting in a low fruit-setting rate.
Solution: When the plant is growing excessively, appropriate chemical regulation should be carried out to control vegetative growth and promote reproductive growth. At this time, growth-control products such as chlorophyll and Jinlv Zhuangyuan can be sprayed to properly control the excessive growth of the plant. However, when spraying, be careful not to repeat the application to avoid pesticide damage.
3. Boron deficiency
When peppers are setting fruit, they have a certain demand for boron. If boron is severely lacking, their fruit-setting rate will be extremely low.
Solution: Boron plays a crucial role in the flower bud differentiation of the plant. For the problem of boron deficiency, foliar fertilizer should be applied in a timely manner to promote flowering and fruit setting.
4. Poor pollination
During cultivation, because the humidity in the greenhouse is relatively high, the pollen becomes sticky and cannot disperse in time, which leads to poor pollination and a low fruit-setting rate, or poor pollination caused by other reasons will also affect the fruit-setting rate.
Solution: After the peak fruiting period of peppers, promptly prune off the branches and weak branches and diseased branches, but do not over-prune, so as not to reduce the fruit-setting rate. At the same time, pay attention to the humidity in the greenhouse to avoid affecting pollen dispersal.
