摘要
通过对保水剂处理苗木方法试验、保水剂适宜配制浓度与用量的试验、保水剂在不同立地条件的施用效果分析等试验,结果表明：在干旱造林地应用保水剂能显著提高植苗造林成活率;1：300浓度保水剂浸根最适宜浓度;栽植穴内撒施10-25 g的保水剂,对提高造林成活率的作用最为显著。
Experiment on water retaining agent with different seedling treatments, various concentrations and dosages of water retaining solutions, different site conditions were carried out. The result showed that water retention agent will significantly increase the survival rate of afforestation in dry area, the most suitable concentration of water retaining agent is 1：300, and that use of 10-25 g of water retaining agent in each planting pit will greatly improve the survival rate.
