The reason of the latest sweet pepper falling flower and fruit

The cultivation of sweet pepper is very common in China, and it is widely distributed in the north and south of China. When planting sweet pepper, we need to do a good job of management, and fine management is the key to ensure the normal growth of sweet pepper. If the management is not good, then sweet pepper will have a lot of problems, affecting its production. And sweet pepper falling flower and fruit is one of them. So what is the reason for the falling flowers and fruits of sweet pepper? The following editor will give you a brief introduction, let's have a look!

1. Temperature reason

Temperature is one of the main reasons for the drop of flowers and fruits of sweet pepper. When planting sweet pepper, if the temperature is higher than 35 degrees, then the flower organ of sweet pepper will be stunted. The style stigma is easy to dry up, which affects the pollination and fertilization of flowers and the phenomenon of falling flowers and fruits. In addition, in summer, when the temperature is higher at night, the plant is prone to overgrowth, which will also lead to flower and fruit drop. Therefore, during the day, we can take measures such as sprinkling mud to reduce the temperature, and at night we can open the vents to cool down. In the flowering period, the temperature should be kept at about 25 degrees, and the temperature difference between day and night is about 10 degrees.

2. Nutritional reasons

Sweet pepper in the growth, the demand for nutrients and water is relatively large. If the soil is dry and short of water, it will affect the fertilizer and water absorption of sweet pepper, resulting in the phenomenon of falling flowers and fruits. But water should not be too much, if too much, the soil is too sticky and heavy, resulting in sweet pepper root respiration and growth are affected, and even retting root phenomenon. Therefore, the soil should be neither dry nor wet. Then when fertilizing, it is necessary to ensure comprehensive nutrition and cooperate with nitrogen, phosphorus and potassium fertilizers. If there is too much nitrogen fertilizer or too little phosphorus and potassium fertilizer, sweet peppers will lose their flowers and fruits due to malnutrition. Especially in the fruiting period, we must pay attention to the application of potash fertilizer.

3. Other reasons

In addition to temperature and nutrition, diseases and drug damage are also one of the main causes of flower and fruit drop of sweet pepper. Especially the virus disease, sweet pepper infected with the virus disease, its main symptom is plant atrophy dead top, resulting in falling flowers and fruits. So if you want to control this disease, you must first eliminate aphids, because aphids are the main pests carrying viral diseases. Then in the summer, because the temperature is very high, so when we use medicine, we should pay attention to control the concentration of the drug, not too high, otherwise it is easy to cause drug damage, which will also lead to sweet pepper falling flowers and fruits.

The above is a brief introduction to the causes of sweet pepper falling flowers and fruits. There are many reasons leading to sweet pepper falling flowers and fruits, when this phenomenon occurs, we should first check the causes of falling flowers and fruits, and then carry out symptomatic prevention to reduce the phenomenon of falling flowers and fruits.
