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

0.6 m×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。

Abstract

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 (60cm 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 20～30mm.
