Background

The significance of weeding is mainly represented in the following aspects:

1. ensuring the normal growth of crops: the growth of weeds can rob resources such as water, nutrients, illumination and the like required by the root system of crops, and the normal growth and development of the crops are affected. Therefore, weeding can reduce the competition of weeds to crops, and maintain the growing environment of the crops, thereby ensuring the growth and development of the crops.

2. Preventing the occurrence of plant diseases and insect pests: weeds are the warm beds of the plant diseases and insect pests, and can provide shelter, rest and propagation places for the plant diseases and insect pests, so that the damage degree of the plant diseases and insect pests is increased. Weeding can reduce the breeding of plant diseases and insect pests and improve the yield and quality of crops.

3. Beautifying the environment and improving the air quality: weed reproduction and growth also affect environmental sanitation and air quality because they can release rotting odors and dust, which can adversely affect human health. The weeding can beautify the environment and improve the ecological environment and the air quality, thereby improving the life quality of people.
