楸树造林方法及其效应的研究

Study on Planting Methods and Their Effect of Catalpa Bungei C.A.Mey.

通过对楸树造林6种方法的对比研究,结果表明:大苗造林的3种方法成活率均达100%,小苗造林的3种方法成活半也达84.4%～85.6%,并在树高、胸径、地径、根系、单株生物量、叶面积、含水量及造林成本等方面,对6种造林方法的效应进行了综合评定,筛选出植苗、截干、插根3种效应最佳的造林方法。

In the experiment of six methods of planting applied to catalpa bu-ngei C.A.Mey,the survjval percentage of three methods of mature seedlingplanting is 100% in all and that of the other three of young seedling planti-ng is 84.4%～85.6%.The effects analysed include tree height,D.B.H,butt dia-meter,root system,individual biomass,leaf area,water content,and plan-ting cost.Three methods—seedling planting,cutting planting and root cutti-ng planting possessing best effect are selected out.
