毛白杨扦插育苗生根难,成活率低,是林业生产上亟待解决的问题.为了寻找出一种投资小、简便易行的育苗新方法,1984年我们采用温水浸泡插穗加地膜覆盖(以下简称浸泡加盖膜)的方法,进行了毛白杨扦插育苗试验,取得了明显效果。现将试验情况报告于后: 一、材料与方法材料与试验地概况:选用地径2厘米左右的箭杆及园叶类型毛白杨,一年生苗于截取插穗:用宽80厘米、厚0.0015毫米的白色薄膜作地膜进行试验.试验地设于许昌市西郊,北纬34°01’,东径113°50’,粘性土质,地下水位1.5米,土壤含有机质1.6％,PH
Populus tomentosa cuttage seedling rooting difficult, low survival rate, is the problem of urgent need to be solved in the forestry production.In order to find out a small investment, easy and convenient method of nursery, in 1984 we use warm water soaking cuttings and mulching (hereinafter referred to as immersion Capped membrane) methods, the Populus cuttage seedling test, and achieved significant results. Now the test report in the later: First, materials and methods Overview of the materials and test sites: Select the diameter of about 2 cm arrow stems and foliage type of white poplar, annual cuttings in interception: with a width of 80 cm, 0.0015 mm thick White film as a film test .Experimental site located in the western suburbs of Xuchang City, north latitude 34 ° 01 ’, east diameter 113 ° 50’, cohesive soil, groundwater level 1.5 m, 1.6% of soil organic matter content, PH
