套袋在杨树植根造林苗上的应用效果

Application Effects of Bagging on Populus Planting Root Seedlings

以1年生杨树植根造林苗为供试材料,秋季造林,第2年春季4月对根桩造林苗进行套袋,以不套袋为对照。对套袋造林苗袋内和裸地温度、袋内和裸地土壤湿度、苗木萌芽、生长、虫害、沙蚀、药害、成活率和造林质量进行比较分析。试验统计分析证明,套袋能够提高造林成活率和苗木质量,能够避免农药对环境污染,降低造林成本,经济、生态和社会效益显著。

Using one-year-old root planting stock of the Populus as the experimental material,afforestation was carried out in the autumn.In April of the following year's spring,the afforestation seedlings that were propagated from stumps were bagged,with non-bagged ones as the control.The study compared and analyzed the temperature inside and outside the bags,soil moisture inside and outside the bags,seedling sprouting,growth,pest infestation,sand erosion,pesticide damage,survival rate,and afforestation quality of the bagged and non-bagged seedlings.The statistical analysis of the experiment proved that bagging could improve the survival rate and quality of afforestation seedlings,avoid environmental pollution from pesticides,reduce afforestation costs,and yield significant economic,ecological,and social benefits.
