摘要
[目的]研究节水抗旱植树袋内土壤含水量变化及对造林树种的影响。[方法]采用不同孔数(孔直径5mm)的植树袋处理不同植株,进行植树袋内土壤含水量的测定,试验设置4个处理,3次重复。[结果]使用植树袋植株的生长状况好于对照植株;使用植树袋土壤水分的入渗速度平缓,土壤含水量也偏高,对照试验的土壤含水量则明显偏低。[结论]植树袋的使用在山地造林方面已见成效,对北京市的困难地造林具有重要意义。
[Objective]The aim was to study the change of the soil water content in the planting green bags and the impact on afforesting tree species.[Method]Planting green bags with different number of holes (diameter of the hole was 5 mm) were used to treat different plants for determining soii water content in the planting green bags,four treatments were set,three times repeat.[Result]The result showed that the growth of plants using planting green bags were better than control experiment;The infiltration rate of soil water was gently with using planting green bags,and the soil water content was high as well,otherwise,the soil moisture content of control experiment was significantly lower.[Conclusion]The use of planting green bags in the mountainous region of afforestation aspects had proved to be effective,and it had an important implication in aspect of afforestation in Beijing.
