内蒙古黄河中上游地区不同树种造林技术对比研究

Comparison on Planting Technology of Different Tree Species in Middle and Upper Yellow River,Inner Mongolia

在黄河中上游地区采用不同造林树种和不同保水剂进行造林,观察不同树种与不同保水剂对造林成活率及林木长势情况的影响。结果表明:使用保水袋能显著提高造林成活率和地上生长量,使用其他保水剂对树种成活率及地上生长量的影响不是很大;造林成活率的大小与选择树种的种类密切相关。

The different tree species and water retaining agents have been used in the afforestation in middle and upper yellow river.The influence of differernt tree species and water retaining agents on the survival rate and growth vigor have been observed.The results show that using water retaining bag can obviously raise the survival rate and the aboveground growth than using other water retaining agent.The survival rate is closely related to the tree species.
