What causes deformed fruit in sweet peppers? How to prevent it
Sweet peppers have high nutritional value, are extremely popular in the market, and offer good economic returns, so many people grow them. However, during the growing process, deformed fruit very easily appears, which not only greatly diminishes the appearance of the sweet peppers but also causes huge losses in yield. So what should be done about deformed fruit in sweet peppers? Let's take a look together.
I. Causes of deformed fruit
Deformed fruit is one of the common physiological diseases of sweet peppers during growth, mainly manifested as abnormal fruit growth. It is caused by sweet peppers encountering severe weather during flower bud differentiation or flowering, such as excessively high or low temperatures, poor flower bud differentiation, poor pollination quality, or incomplete fruit development.
II. Prevention methods
1. Fertilization
When growing sweet peppers, be sure to pay attention to the supply of fertilizer, especially the supply of trace elements such as boron and calcium, so as to avoid the occurrence of deformed sweet peppers. When fertilizing, also pay attention to the application rate of nitrogen fertilizer. Applying too much nitrogen fertilizer will lead to excessive vegetative growth of branches and leaves, which competes with fruit growth for water and nutrients. Because the fruit cannot obtain sufficient nutrients, it forms deformed fruit. Therefore, the application rate of nitrogen fertilizer must be controlled, while increasing the application of potassium fertilizer can help sweet peppers absorb nutrients, water, and light better, and promote the growth of sweet peppers more effectively.
2. Temperature control
When sweet peppers are flowering and setting fruit, temperature is very important and must not be too high or too low. If the temperature exceeds 35 degrees or stays above 32 degrees for 2 consecutive hours, sweet peppers will show poor pollination or poor fertilization, forming deformed fruit. Around the Spring Festival, also pay attention to changes in temperature and ground temperature. If it is too low, it will also affect fruit setting in sweet peppers. Applying biological fertilizer around the Spring Festival can promote normal fruit setting in sweet peppers.
3. Controlling excessive growth
If the plants grow too vigorously, the probability of deformed fruit will increase. The normal growth of sweet pepper fruit can be ensured by spraying growth regulators and by pruning branches and removing shoots. If sweet peppers cannot set fruit, it may also lead to excessive plant growth. Spraying chlormequat and adjusting the temperature can ensure normal plant growth, which is beneficial to fruit development.
