宜昌楠苗木繁育技术初步研究

Preliminary Studies on Seedling Propagation Technology of Machilus ichangensis Seedling

通过对宜昌楠(Machilus ichangensisRehd.Et)进行种子育苗、幼苗移栽和定植苗的修剪等试验,结果表明:宜昌楠种子宜在元旦前后播种并覆盖发酵草,出苗率可达到98%;每年3月幼苗根部打泥浆后移栽,幼苗成活率达到95%;对定植苗进行修剪,特别是春剪有利于侧芽的增长和主茎基部的增粗。

After the experiment that the Machilus ichangensis seed was bred, the seedlings were transplanted and the planting-stock seedlings were trimed. The results indicated： The rate of seedlings emergence might achieve 98 percent when seeds were sowed and covered by fermented grass in New Year＇s Day around. The seedlings survival rate might reached 95 percent when seedlings were transplanted after their root was treated with slurry in March every year. The planting-stock seedlings were trirned. The above including spring pruning especially was advantageous to the lateral bud growth and main stalk base increasing thickly.
