Do these two precautions in advance to keep winter vegetable greenhouses away from pests
Now that it has reached the cold winter, it is reasonable to reduce the temperature of the pests. However, since it is now planted in greenhouses, the temperature and humidity inside the greenhouse are relatively high, which is more suitable for pest breeding. Farmers of vegetables have also begun to worry about how to remove pests, because once they are invaded by pests, they will soon be corrupted or even die if they are not managed. Therefore, in order to prevent pests in vegetable greenhouses, farmers must do the following two work to prevent pests. 1. Picking seeds for insect resistance Prevent pests and diseases from starting from seeds, because seeds are the main source of viral infection. When selecting seeds, we should choose seeds that are not diseased, or use seedlings to raise seedlings. When seedlings, we can use seed soaking or heat sterilization. These are the first means of prevention and control of pests. 2. Timed field management During the growth of vegetables, the suitable environment for greenhouses becomes an excellent environment for the growth of viruses and pests. Therefore, in order to control the growth and rapid propagation of pests, some drugs for deworming can be appropriately used. Even if farmers have adopted seeds that are free of viruses and pests, the weeds in the field may be carriers of pests, which will be transmitted to vegetables after the onset of disease. Therefore, weeds should be removed in time, or the infected plants infected with insects should be removed in time. . When the pest is indeed a bit more, you can also use the vegetable-induced resistance agent or the light that attracts the pest, and then eliminate the adult to reduce the damage of the pest. Regular field management of vegetables is a key to preventing or eliminating pests. The above is the two pest prevention measures of the winter vegetable greenhouses compiled by Huinong. The final Xiaobian wants to say that the farmers should not worry too much about the pests in the vegetable greenhouses. It is especially important to prevent pests.
