Description

technical field [0001] The invention relates to the technical field of agriculture and animal husbandry, in particular to a method for controlling weeds by planting grass. Background technique [0002] Weeds are plant groups that hinder and interfere with human agricultural production, and will affect the growth, yield and quality of Chinese medicinal materials and fruit trees. Weeds will waste the available land resources of Chinese medicinal materials and economic fruit forests, so the problem of weeds is always an important part of field management in the ecosystem of Chinese medicinal materials and economic fruit forests. Although chemical herbicides can effectively control weeds, they will also lead to new problems such as increased weed resistance, endangering human health, and destroying ecological balance. Therefore, for many years, efforts have been made to change the growth environment of weeds or change the distribution pattern, growth status and harm of weed ...
