A few days ago, the author went to the countryside to participate in the strawberry picking festival and found that the strawberry in the ridge of the greenhouse was planted with garlic every 0.5-1 meter. According to reports, garlic can prevent strawberry anthracnose, fan disease, etc., some of the underground pests are also particularly afraid of the taste of garlic, using this method of biological control of pests and diseases, 1 mu of land can save more than 800 yuan of pesticide costs, so that both pest control No pollution, the fruit shape and taste of the strawberries are better.
Today, many people have watched water spirits and colorful fruits and vegetables but they dare not feel at ease. The reason is that some farmer friends often use highly toxic pesticides to kill insects. The output of fruits and vegetables is improved, but pesticide residues have become a problem. The public hazard has also objectively affected the sales of fruits and vegetables. The credibility of healthy fruits and vegetables has been greatly reduced. In the end, it is the fruit farmers and vegetable farmers. Utilizing the symmetry between fruits and vegetables, pursuing advantages and avoiding harm, and achieving energy-saving and environmentally-friendly prevention and control of pests and diseases are instructive for ensuring food safety from farmland to table.
In fact, not only strawberries, leeks and other fruits and vegetables but also biological methods can prevent pests and diseases. The main cause of damage to leeks is crickets. When it is serious, there are dozens or even hundreds of pods under a string of leeks. Farmers have to use large doses of medication and sometimes even use highly toxic pesticides, which often leads to excessive pesticide residues. Horseradish is a magic weapon used to disinfect leeks root. Horseradish is a high concentration of mustard, which is extracted from cruciferous plants such as rapeseed. It is safe and effective, and it is used for disinfection of greenhouses and soils. In addition, two methods can also be used, one is to use electric field defogging equipment to defogging and dehumidifying the greenhouse, and the other is to use rice bran, pine needles, peanut shells and other sprinkled in the leek between the rows to improve the buffer moisture environment.
The use of pests to treat pests, the use of bacteria to treat pests, the use of bacteria to prevent disease, and the use of insect hormones to control pests have played an important role in the planting industry. I hope this advanced technology will be grasped by more and more farmers' friends to allow food production and fruits and vegetables. The industry produces more "green."
