不同类型穗条对树木嫩枝扦插成活的影响

试验研究了剪穗母树的年龄、长势状况,所采枝条部位,剪穗部位优劣状况对扦插成活率的影响。结果表明:树木嫩枝扦插剪穗应在母树年龄较小,无病虫害,生长旺盛的母树上采集;树木嫩枝扦插剪穗应在母树基部旺盛的萌生条或顶端旺盛枝条及当年生幼树的顶端枝条的中部和上部剪取;所剪插穗要保证长度一般在15cm以上,要保留充足的叶片。

Effects of Different Types of Cuttings on Survival Rate of Softwood Cuttings of Trees

Tree age,growing conditions,the part of cutting branch were studied.The effects of good and bad condi-tions on parts of cuttings on survival rate of seed tree were studied.Result shows that:the mother trees with small tree age,no pests &vigorous growth should be selected to cut ear for softwood cuttings;the parts (sap shoot on the vigorous base of the seed tree,on the vigorous top branch &top branch in the very year )should be selected to cut;cuttings should be cut in the middle and upper branches;length of cuttings should be generally ensured above 1 5 cm ,retaining with sufficient blades.
