Peppers often appear on the surface of the greenhouse. The peppers are not sold well after being marketed, and the income of vegetable growers will be greatly reduced. The following reasons will lead to this phenomenon, and farmers should deal with the disease.
Virus disease Virus disease in pepper plants may result in bumps and bumps, but usually with light brown stripes. Virus disease generally does not suddenly burst, and often shows an increasing trend. For sheds that have already exhibited symptoms of viral disease, they can be sprayed with a 2% solution of Ningnanmycin at 500 times and other agents, and sprayed with 6,000 times more liquid to promote the growth of peppers. At the same time to prevent insects such as whiteflies and locusts in the shed, such as sucking mouthparts to pass through poisons, and smoke prevention and control with special killing smoke agents is effective.
There are two types of injury caused by pesticides: one caused by excessive spraying, and the other caused by excessive use of hormones. In the production, spraying and preventing disease or pneumoenzymes are essential for regulating the growth of the plants. Since the peppers are young during the growth process (especially in the pre-expansion period), they are stimulated by high concentrations of drugs and hormones. Symptoms appear uneven. Therefore, the administration of pharmaceuticals and hormones must be scientific, avoid blindly medication and repeated medication.
Physiological diseases When the plants are weak, poor nutrition or inappropriate temperature, it will affect the differentiation of flower buds, resulting in malformed fruit, causing no long fruit, fruit no fruit. The lack of seeds in the fruit will make the fruit surface slightly concave, but generally no brown stripes. Should pay attention to regulating plant growth and shed environment, make-up boron fertilizer to ensure the smooth progress of flower bud differentiation.
