What are the latest solutions to the low fruit-setting rate of bell peppers?
Bell peppers differ from other peppers in that their taste is not only not spicy but also slightly sweet, and they also have the advantages of high yield and good returns, making them a very suitable crop for cultivation. However, many bell pepper growers report a low fruit-setting rate, so how should this be solved? Let's find out together.
1. Promote roots and strengthen fruit
The root system of bell peppers is relatively weak, so during cultivation you must ensure the soil has sufficient air permeability, which helps promote the rooting and development of bell peppers. In summer, when temperatures are high, ridged planting is not suitable, otherwise it may burn the roots; instead, flat-bed cultivation should be used. Therefore, it is recommended to use biological bacterial fertilizer to improve the soil and promote root growth and development, cultivate strong fruit, and thereby increase the disease resistance and stress resistance of bell peppers, which can reduce the occurrence of a low fruit-setting rate.
2. Control temperature and water
During high summer temperatures, you must control temperature and humidity well, otherwise flower and fruit drop is very likely to occur. Generally, when the temperature is above 35 degrees, it will cause poor differentiation and uneven pollination in bell peppers, thus affecting the fruit-setting rate, so the temperature should be kept within 35 degrees; if it is too high, find a way to bring it down. In addition, bell peppers like moisture and fear waterlogging. If soil humidity is too high, it will also affect the fruit-setting rate, so watering should not be by flood irrigation, or after watering take measures such as hoeing to ensure the soil is alternately dry and wet, and drain promptly during the rainy season.
3. Control excessive growth
Under high-temperature and high-humidity conditions, bell peppers are very prone to excessive growth, and the branches and leaves are very prone to excessive growth. If temperature and water control have poor effect, then growth regulators should be used to control the excessive growth of the plants. Commonly used growth regulators include chlormequat or daminozide, which can effectively control the vegetative growth of the plants, promote reproductive growth, and also help increase the fruit-setting 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 a lower fruit-setting rate, so spraying liquid fertilizer containing boron during the flowering period can not only supplement nutrients for the plants, but also reduce flower and fruit drop, effectively increasing the fruit-setting rate.
