摘要
在调查分析不同整地方式、整地时间、造林树种、造林时间与造林成活率关系的基础上得出 ,在西北干旱地区 ,采用汇集径流整地方式、夏秋两季整地、春季造林、青杨插干造林成活率较高 ,效果较好。另外 ,从林木生长状况即当年侧根数和高生长量来看 。
Analyses on relationship between the survival rate of afforestation and patterns of site preparation and time, tree species and afforestation season showed that higher survival rate could be got if site preparation were done in Summer and Autumn for collecting run off and afforestation in Spring, for Populus cathayana a priority.The results is also verified by counting tree root numbers and high growth.
