摘　　要：本文主要通过对比常规造林、使用集水托盘和土壤高效持水改良剂造林在黄南州干旱区造林绿化上的应用效果,来阐述集水托盘和土壤高效持水改良剂的优势。研究显示:应用集水托盘和土壤高效持水改良剂在干旱地区造林可以显著提高苗木成活率,有效提高土壤温度和水分含量,明显增强土壤保墒效果,同时还可以降低营林成本。因此,应用集水托盘和使用土壤高效持水改良剂比常规造林效果明显,具有良好的示范作用。This paper mainly expounds the advantages of catchment tray and soil high-efficiency water-holding improver by comparing the application effects of conventional afforestation,using catchment tray and soil high-efficiency water-holding Improver in afforestation and greening in arid areas of Huangnan city.The research shows that the application of catchment trays and soil water-holding improvers in afforestation at arid areas can significantly improve the survival rate of seedlings,effectively increase the soil temperature and moisture,significantly enhance the soil moisture preservation effect,reduce the cost of afforestationat at the same time.Therefore,the application of catchment trays and the use of high-efficiency soil water-holding improvers were more effective than conventional afforestation and had a good demonstration effect.
