干水造林技术在干旱沙区造林中的应用,为干旱沙区植树造林和生态环境建设开辟了一条新的途径。本文系统地分析了干水造林技术在干旱沙区应用中的可行性和重要性,并对应用过程中存在的问题进行了较深入的探讨。干水凝胶盒向土壤中持续输送水分长达 4个月之久,能明显提高土壤含水率和苗木成活率,使土壤含水量始终保持在 2.0 %以上,有时达 5.0 %以上,促进苗木在生长季节的旺盛生长

The technology of dry water was Utilized in drought desert area, It creates a new rout for plant ing and environment instruction.This article not only analyzed feasibility and importance of ut ilization on tech-nology of dry water, but also deeply discussed exiting problems.A packet of dry-water may moisture to sur-rounding soil for 4 months.It can obviovsly increase soil water content and seedling, maintain the soil water transter above 2.0 percent even over 5.0 percent in the rainy season.It can also obviously improve seedling growth in the processing.
