What are the benefits of using herbicides in orchards?

What are the benefits of herbicide application in orchards? Orchard barnyardgrass is an important operation in soil management. It requires about 4 times a year under clearing conditions. It takes 8 to 10 workdays per mu, and the labor intensity is also large. If herbicides are applied, chemical weeding will not only greatly reduce the labor intensity, but also speed up the removal of weeds to achieve the purpose of labor saving, labor saving, fertilizer and field maintenance. In summary, the application of herbicides has the following benefits: (1) Accelerate herbicides and increase efficacy: Herbicides are sprayed in a targeted manner using a knapsack sprayer, spraying at least 1 mus per working day, and artificial valerian for 2 days per mus of the orchard. Therefore, weeding herbicides are at least twice as effective. (2) Blight grassland, rotted fertilizer field: Most herbicides should be applied when they are covered with grass. Killed weeds cover the surface of the earth. After rot, it will increase humus and nutrient elements in the soil. When weeding the grass, we must turn the grass and clear it, otherwise it will be difficult to work. In addition, chemical weeding can also reduce the mechanical destruction of the topsoil and help maintain the soil structure. (3) Thorough weeding and long-lasting results: Orchards, especially the result parks, use more killing herbicides. After spraying, all weeds can be killed. Even the most difficult to remove thatch, reed, spinach, purslane, etc. can kill, in addition to the possibility of resurrection is very small. Unlike perennial grass, perennial, deep-rooted weeds can only get rid of the above-ground parts, and they regenerate shortly afterwards. Therefore, chemical weeding can be completely eliminated, and the long period of validity.
