Physical preventing and treating method of diseases and insect pests for shed vegetables

Abstract

The invention discloses a method for physical prevention and control of vegetable diseases and insect pests in greenhouses. The physical prevention and control method is to remove the diseases and insect pests in soil by means of a combination of an ultrasonic generator and a blower. The beneficial effects of the present invention are: the method for physical prevention and control of vegetable pests and diseases in greenhouses provided by the present invention can achieve the goals of increasing production, high quality, disease resistance and high efficiency while reducing the amount of chemical fertilizers and pesticides used, realize ecological agriculture, and promote sustainable agricultural development. Among them, sound waves make sensitive pests feel disgusted or fearful, affecting the normal eating of pests, making it difficult for them to survive, reproduce, or leave voluntarily. It has been verified that sound waves have a significant effect on repelling stubborn pests such as aphids and red spiders. At the same time, The air vortex caused by the blower can reduce the adaptability of pests to the environment. The combination of the two can promote each other to achieve a better insect repellent effect.

Description

technical field [0001] The invention relates to a physical control method for vegetable diseases and insect pests in greenhouses. Background technique [0002] Vegetables are indispensable and irreplaceable necessities in people's lives. In the last century, chemical agriculture, mainly characterized by chemical fertilizers and pesticides, greatly increased the yield of vegetables and made a huge contribution to solving the problem of food and clothing. Later, people gradually discovered that the long-term and excessive use of chemical fertilizers and pesticides has caused problems such as soil fertility decline and increased resistance of pests and diseases, and the use of chemical fertilizers and pesticides has to be increased. As a result, the drug residues in vegetables have adverse effects on people's health. With the improvement of the quality of life, people's awareness of food safety is constantly increasing, and the demand for green vegetables and pollution-free v...
