Effect of Cutting Propagation Density on Survival Rate and Qualities for Low Branches of Ramie Cutting Plant

With three ramie varieties of Zhongzhu No 1,Xiangzhu No 3,Tris-l and a new line R057 as the materials,effect of different cutting density on shoot survival rate,stem height increment,root dry weight per plant and branching characteristics of cutting plant for low branches of ramie were studied.The results showed that shoot survival rate,stem height increment and root dry weight per plant in the four materials of cutting plant for low branches of ramie had significant differences among the treatments.The same results showed in branch number,minimum and maximum branches bit length.For all above,the optimal treatment of cutting propagation density should be about 100 per square meter.
