摘要
通过对元谋干热河谷现有水土保持植物的试验观测及水土保持林营造技术的试验研究，初步选出适宜于当地气候特点的水土保持林草种１１个，总结出９０～１００ｄ为袋苗移栽的最佳苗龄，０．６ｍ×０．６ｍ水平沟整地，６月下旬－７月上旬定植为最佳时节的水土保持林营造技术。
The afforestation techniques which initially showed suitable for the arid hot valleys in Yuanmou county, Yunnan province were studied. The results suggest that three steps of measures should be taken to improve the survival rate of the tree grass employed in the arid hot valleys. First, to prepar land by digging level ditch (60 cm in depth and width). Secondly, to raise saplings with polybag during the period of March 10 to April 10(90～100 days before transplanting). Third, to transplant saplings during the period of June 20 to July 10 when the precipitation reaches 20～30 mm.
