摘要
对一年生不同地径构树截干移植后的根系生长特性进行了研究。结果表明:地径大于1.5 cm的苗木截干移植(留茬高度为15～20 cm)处理的效果最好,截干移植后当年成活率达90%,而且主根和一级侧根长度、侧根个数、根系生物量均比未截干对照有所增加。
The growth characteristics of the root system of the transplanted cuttings of annual Broussonetia papyrifera with different ground stem diameters were studied.The results showed that transplanting the cuttings（the height of the residual stubble was from 15 to 20 cm） of annual Broussonetia papyrifera with the stem diameter of above 1.5 cm got the best effects,the survival rate of the transplanted cuttings in the same year of transplanting reached 90%,and the length of both main root and the first lateral root,the number of lateral root and the biomass of root system all increased in comparison with those of the control（no transplanting the cuttings）.
