果园杂草对果树的危害很大，能直接或间接影响果园水果生产。杂草不但与果树

Orchard weeds are very harmful to fruit trees and can directly or indirectly affect fruit production in orchards. Weeds not only compete with fruit trees for nutrients and affect their growth, but are also intermediate hosts and overwintering hosts for various diseases and insect pests. When weeds grow more luxuriantly, it is easy to induce pests and diseases, and reduce the yield and quality of orchard fruits. According to statistics, weeds can reduce the yield of fruit trees by 10% to 20%, so weeding is an important means of maintaining orchards. Scientific and effective control of weeds can not only ensure the healthy growth of fruit trees, improve fruit quality and yield, but also reduce the occurrence of pests and diseases in orchards. Because the environment is more suitable and ventilated, the orchard is prone to overgrown weeds. Therefore, regular weeding in the orchard is an important part of the standardized management of the orchard. Regarding the weed control in the orchard, at this stage, there are mainly various weeding methods such as manual weeding, chemical weeding and mechanical weeding. Manual weeding is labor intensive, time consuming, and work efficiency is not high. Although pesticide weeding saves labor and time, it has great side effects. On the one hand, it is easy to cause pesticide residues in fruits and reduce the quality of fruits. People are more concerned about food safety, and the most serious food safety problem in fruits is pesticide residues. Therefore, in order to ensure the safety and quality of fruits, orchards should use as little or no pesticides as possible. On the other hand, pesticides are difficult to decompose, and residues in the soil will not only continue to damage fruit trees, but also cause ecological problems, which is contrary to the purpose of sustainable agricultural development. Mechanical weeding is fast and efficient, and will not cause any environmental problems. The cut weeds can also cover the soil and improve the physical and chemical properties of the soil. Therefore, mechanical weeding of the orchard is a very important measure. Of course, when mechanized orchard weeding, we must adhere to the concept of combining agricultural machinery and agronomic requirements to ensure the effectiveness of operations and promote the mechanized development of orchards.

Orchard weeds are very harmful to fruit trees and can directly or indirectly affect orchard fruit production. Weeds not only compete with fruit trees for nutrients and affect their growth, but are also intermediate and winter hosts of various pests and diseases. When weeds grow more lush, it is easy to induce pests and reduce the yield and quality of orchard fruit. According to statistics, weeds can cause fruit trees to reduce production by 10% to 20%, so weeding is an important means to maintain orchards. Scientific and effective control of grass damage can not only ensure the healthy growth of fruit trees, improve fruit quality and yield, but also reduce the occurrence of pests and diseases in orchards. Because the environment is more suitable, and ventilation and light, orchards are prone to weeds. Therefore, regular weeding of orchards is an important part of the standard management of orchards. For orchard weeding this piece, at this stage there are mainly artificial weeding, pharmaceutical weeding and mechanical weeding and other weeding methods. Artificial weeding labor intensity is large, labor time-consuming, operating efficiency is not high. Although pesticide weeding saves time, but the side effects are also very large, on the one hand, easy to cause fruit pesticide residues, reduce fruit quality. Now people are more concerned about food safety, and the fruit has the most serious food safety problem is pesticide residues, so in order to ensure the safety and quality of fruit, orchards try to use less or no pesticides. On the other hand, pesticides are difficult to break down, residues in the soil will not only continue to harm fruit trees, but also cause ecological problems, contrary to the purpose of sustainable agricultural development. Mechanical weeding is quick and efficient, does not cause any environmental problems, cut off weeds can also cover the soil, improve the physical and chemical properties of the soil. Therefore, the mechanical weeding of orchards is a very important initiative. Of course, in the mechanization of orchard weeding, we must adhere to the concept of combining agricultural machinery and agronomic requirements, to ensure the effectiveness of operations, and promote the mechanized development of orchards.

Weeds in orchards do great harm to fruit trees and can directly or indirectly affect fruit production in orchards. Weeds not only compete with fruit trees for nutrients and affect their growth, but also are intermediate hosts and overwintering hosts of various diseases and pests. When weeds grow more luxuriantly, it is easy to induce diseases and insect pests, and reduce the yield and quality of orchard fruit. According to statistics, weeds can reduce the yield of fruit trees by 10% ~ 20%, so weeding is an important means to maintain the orchard. Scientific and effective control of weeds can not only ensure the healthy growth of fruit trees, improve fruit quality and yield, but also reduce the occurrence of diseases and pests in orchards. Because of the suitable environment, ventilation and light transmission, the orchard is prone to weeds. Therefore, regular weeding is an important part of orchard management. At present, there are many kinds of weeding methods, such as artificial weeding, chemical weeding and mechanical weeding. Manual weeding labor intensity, labor-consuming, time-consuming, operation efficiency is not high. Although weeding with pesticides saves labor and time, it also has great side effects. On the one hand, it is easy to cause pesticide residues in fruits and reduce the quality of fruits. Now people pay more attention to food safety, and the most serious food safety problem of fruits is pesticide residues, so in order to ensure the safety and quality of fruits, orchards should try to use less or no pesticides. On the other hand, pesticides are difficult to decompose and remain in soil, which will not only damage fruit trees, but also cause ecological problems, which is contrary to the purpose of sustainable development of agriculture. Mechanical weeding is fast, efficient, will not cause any environmental problems, cut weeds can also cover the soil, improve the physical and chemical properties of the soil. Therefore, the mechanical weeding of orchard is a very important measure. Of course, in the orchard mechanization weeding, we must adhere to the concept of combining agricultural machinery and agronomic requirements, ensure the effectiveness of the operation, and promote the development of orchard mechanization.<br>
