营养体对树木嫩枝扦插成活的影响

Effects of Vegetative on Survival Rates of Softwood Cuttings of Trees

在嫩枝扦插育苗中,通过对所选剪穗母树的年龄、长势状况,所采枝条部位,剪穗部位优劣状况等不同因素对嫩枝扦插成活率的影响研究,结果表明:用于嫩枝扦插剪穗的种条应在母树年龄较小、无病虫害、生长旺盛的优势母树的基部萌生条或顶端旺盛枝条及当年生幼树的顶端枝条上采集;剪穗应在枝条的中部和上部剪取,长度要在15cm以上。

Effects of different factors(age and growing conditions of mother tree,good and bad condition for part of the cutting branches &cutting spike)on survival rates of softwood cuttings were studied.Result shows that stripe should be collected in base sprouted shoots with small-aged,no pests &advantaged mother trees which grow vigorously,topped vigorous branches,topped branches of saplings in the very year.Cuttings should be cut in middle and upper part of the branches,length being above 15 cm.
