Abstract: In order to explore the ecological and healthy methods of grass control in Chinese prickly ash orchard, two new weeding methods, weeding cloth mulching and mechanical weeding were designed. Compared with the conventional management, the effects of grass control, soil nutrients, soil moisture and the economic benefits of three methods of grass control were analyzed. The results showed that the best control effect was achieved by weeding cloth mulching method, for which the growth of weeds in the Chinese prickly ash orchard could be effectively controlled. The three methods of grass control had different control effects on main weeds. Weeding cloth mulching method had a significant effect on soil nutrients. From the analysis of cost input and output benefit, the investment in weeding cloth mulching method was the lowest, and output effect was the highest. Conclusion: from the point view of green, safety and economy, weeding cloth mulching method was the most suitable way to control grass in Chinese prickly ash orchard.
