What to do about low fruit set in bell peppers? These solutions you need to master
Bell peppers differ from other peppers: not only are they not spicy, they also have a slight sweetness, and they offer the advantages of high yield and good returns, making them a very suitable crop for the market. But many bell pepper growers report low fruit set, so how can this be solved? Let's take a look.
1. Promote roots and strengthen fruit
The root system of bell peppers is relatively weak, so during cultivation the soil must be kept sufficiently airy, which helps promote root growth and development in bell peppers. In summer, when temperatures are high, ridge planting is not suitable, otherwise it may scorch the roots; instead, flat-bed cultivation should be used. Therefore, it is recommended to use biological bacterial fertilizer to improve the soil and fertility, promote root growth and development, and cultivate strong fruit, so as to improve the disease resistance and stress resistance of bell peppers, which can reduce the occurrence of low fruit set.
2. Control temperature and water
During high summer temperatures, temperature and humidity must be well controlled, otherwise flower and fruit drop easily occurs. Generally, when the temperature is above 35°C, it causes poor differentiation and uneven pollination in bell peppers, thereby affecting fruit set, so the temperature should be kept within 35°C; if it is too high, find a way to bring it down. In addition, bell peppers like moisture but fear waterlogging. If soil humidity is too high, it will also affect fruit set, so watering should not be flood irrigation; alternatively, after watering, hoe the soil to ensure the soil is dry-wet alternating, and drain promptly during the rainy season.
3. Control excessive growth
In a high-temperature, high-humidity environment, bell peppers are very prone to excessive vegetative growth, and the branches and leaves grow excessively. If temperature and water control have poor effect, then a growth regulator should be used to control the excessive growth of the plants. Commonly used growth regulators include chlormequat or daminozide, which can effectively control vegetative growth, promote reproductive growth, and help increase the fruit set rate of bell peppers.
4. Spray micronutrient fertilizer
Boron is one of the essential elements for flower bud differentiation in bell peppers. Boron deficiency in bell peppers often leads to poor flower bud development and thus low fruit set, so a boron-containing liquid fertilizer can be sprayed during the flowering period. This not only supplements nutrients for the plants, but also reduces flower and fruit drop, effectively increasing the fruit set rate.
