How to scientifically manage home-grown fruit trees and orchards growing with grass in rural areas?

Weeds in orchards have long been criticized. On the one hand, when there are too many weeds and they are luxuriant, they will compete with fruit trees for nutrients, light, and growing space, thereby reducing fruit tree yields and affecting income. On the other hand, in orchards where weeds are out of control, pests and diseases often occur. Weeds not only provide habitat for pests and diseases but also serve as intermediate hosts for annual weed occurrences. To sum up, weed control is a very important part of orchard management

Chemical weeding Chemical weeding is also what we often call weeding. Since it was introduced to China in the 1950s, it has been used until now because it saves time, labor, and is cost-effective. However, chemical weeding is like a double-edged sword, with obvious pros and cons. Unreasonable use can easily cause drug damage and tree damage; in addition, long-term use of herbicides will not only increase weed resistance, but also affect the ecological environment. Therefore, it is unwise to rely solely on chemical weed control.

Physical weeding mainly includes labor, machinery, mulch, etc. Of course, it also includes laser, flame, electric weeding, etc. However, the latter list is very low in practical applications due to high cost or imperfection. Hand weeding is the most primitive method. It's thorough and has no side effects, but it's very ineffective. It is usually carried out in small orchards under careful management, or in combination with other weeding methods, such as between-row chemical weeding and manual weeding. When mulching and weeding the orchard, manually remove some weeds, etc.

Biological weeding is most common in ecological farming under forests. Herbivores eat grass, such as chickens, ducks, geese, sheep, etc. However, these livestock and poultry are not well trained and can have the opposite effect if not handled properly. For example, chickens like to climb high and dig into the soil, sometimes damaging trees and root systems. The other is biotechnological weeding, which refers to the use of industrially produced microorganisms, plants, animals and other natural organisms or their tissues and metabolites as biological agents for weeding to achieve the purpose of weeding.

Do all weeds in grass orchards have to be eradicated? Practice has proven that benign weeds in orchards can improve the physical and chemical properties of the soil, maintain water and soil, and enhance the ability to withstand harsh climate environments. So instead of weeding, control weeds. Currently, there are two ways to grow grass. One is natural growth, which eliminates evil and protects good, and the other is artificial grass. Grass is used to treat grass. Common grass species include ryegrass, bahiagrass, vinegrass and clover.
