AI Technical Summary

Technical Problem

In the prior art, American ginseng planting in natural forests has vigorous weed growth. The use of chemical herbicides will cause pesticide residues and biodiversity damage. Artificial weeding is time-consuming and labor-intensive, making it difficult to effectively control weeds, affecting American ginseng growth and forest ecosystems.

Method used

Weeds are removed before American ginseng planting, and covered with unbreaked American ginseng seeds and natural dead branches and leaves. Combined with the treated cosmos, dandelions and light-leaf fern leaf mixture to cover the soil, use woodland resources to inhibit weed growth and avoid the use of chemical herbicides.

Benefits of technology

Significantly reduce the weed biomass in forest land, increase the rate of American ginseng seedlings, improve the soil environment, achieve an ecologically sustainable planting model, reduce the use of chemical herbicides, and protect biodiversity.

Abstract

The invention provides a method for reducing weeds in the woodlands around American ginseng, and belongs to the field of American ginseng planting technology. The specific method is weeding from July 15 to August 15, sowing uncracked seeds, litter recovery, and natural germination; light-leaved fern blades, cosmos blades, and dandelion blades are mixed evenly to obtain a weed suppression mixture, and forest management is carried out in the spring of the second year. The weed suppression mixture is covered on the ground after sowing in March to April of each year, with a covering thickness greater than 2 cm, and the covering is evenly avoided from exposing the soil surface, and harvested in 8 years. The planting method of the present invention makes full use of understory resources, suppresses the growth of most weeds in the woodlands, significantly reduces the biomass of weeds, eliminates the application of herbicides, controls the impact of forestland weed damage on the growth of American ginseng, and is a kind of ecologically sustainable planting model.
