Pepper is a kind of vegetable that we eat almost every day. It is also a common seasoning vegetable. In rural areas, almost every household will plant a few pepper fields. But the pepper is very easy to fall in the planting process, so what is the reason? Is there any good preventive measures? Let Xiaobian explain it now.
First, the reason why the pepper falls and falls
1. The cultivation measures are not in place, causing the falling flowers of the peppers
If the cultivation density of the pepper is too large, or if the nitrogen fertilizer is applied too much, it is easy to cause the pepper plant to grow. When the nutrient and reproductive growth of the pepper loses its balance, the flower buds of the pepper and the fruit of the pepper will appear to be undernutrient and cause to fall off. Especially in the cultivation of greenhouses, peppers are more prone to occur.
2. Unfavorable climatic conditions cause peppers to fall and fall
In winter and spring, greenhouses often encounter insufficient light and low temperature, which affects pollination. Even if pollination, the fruit is poorly developed and easy to fall off. This is more obvious in rainy and snowy weather. When the ventilation in the greenhouse is poor, and the humidity is too high, the pepper flower can not be properly scattered, which makes it difficult to complete the pollination and fertilization.
3, pests and diseases cause the loss of capsicum
If peppers develop diseases such as viral diseases, anthracnose, and leaf blight, they are also likely to cause falling flowers and fruits. For example, after the infection of the virus, the pepper often has a dead-top phenomenon, causing the flowers to fall. In addition, tobacco budworms and cotton bollworms will eat capsicum fruit, which will also cause fruit to fall off.
Second, the preventive measures for the falling and falling of the pepper
1. After the pepper is planted, it is necessary to strengthen the ventilation and drainage in the greenhouse. The daytime temperature in the shed is maintained at 25-28 °C, the night is 15-18 °C, and the flowering period is at least 15 °C.
2, pepper greenhouses advocate sub-film irrigation, it is best not to flood the water.
3. Improve the resistance of pepper plants through scientific cultivation management, and pay attention to the prevention and control of peppers.
All in all, if you want to prevent the fall of the flowers, you should start from strengthening the cultivation and management, mainly to cultivate strong seedlings, timely planting, rational close planting, scientific fertilization, and try to ensure the suitable growth environment of peppers.
