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 application of dry-water afforestation technology in afforestation in arid sandy area opens up a new way for afforestation and ecological environment construction in arid sandy area. This paper systematically analyzes the feasibility and importance of dry-water afforestation technology in the application of arid sand area, and discusses the problems existing in the application process in depth. The continuous delivery of water to the soil by the dry hydrogel box can last up to 4 months, which can obviously improve the soil moisture content and seedling survival rate, and keep the soil water content above 2.0%, and sometimes over 5.0% , To promote the vigorous growth of seedlings in the growing season
