Abstract：In order to improve the production technology and economic benefits of Polygonatum cyrtonema,useing four substances including pine needles,sheep manure,bran,and rice straw for mulching treatment,and studying the effects of different mulching on growth of Polygonatum cyrtonema such as branching,ground diameter,plant height,root fresh weight and soil nutrients.The results showed that mulching treatment of pine needles,sheep manure,bran,and rice straw can promote branching,increasing by 54.55％,100％,45.45％,and 72.73％,respectively.Compared with the control,sheep manure,rice straw,and bran can significantly increase the ground diameter and root fresh weight(P＜0.05),while sheep manure and rice straw can significantly increase the ground diameter and root fresh weight(P＜0.01).All four mulching treatments can significantly improve the plant height(P＜0.01);The ground diameter and plant height of sheep manure mulching were significantly higher than those of bran and pine needles mulching(P＜0.01),but there was no significant difference between rice straw mulching and bran mulching and pine needle mulching(P＞0.05).The root fresh weight among different treatments showed that sheep manure mulching was significantly higher than the other three mulching treatments(P＜0.01).Overall,the promotion effect of mulching treatment on the growth of Polygonatum cyrtonema is as follows:sheep manure＞rice straw＞bran＞pine needles.The four mulching treatments all improved soil nutrients,and the total nitrogen,hydrolyzed nitrogen,total phosphorus,available phosphorus,total potassium and available potassium were significantly higher than the control,with sheep manure mulching the most significant improvement.By comprehensive comparison,sheep manure mulching has the best effect on promoting the growth of Polygonatum cyrtonema and improving soil nutrients,which is beneficial for increasing the yield of Polygonatum cyrtonema and can be used as the first choice for mulching.
