摘  要:
在西藏半干旱河谷地进行造林试验,采用了覆石头、覆膜、覆秸秆、覆鸡蛋托盘、用保水剂等不同造林技术措施,研究了不同措施下藏川杨叶片生理生化指标的变化。结果表明,以上措施在一定程度上都提高了藏川杨的造林成活率,叶片的相对含水量和叶绿素在不同措施下都有所提高,可溶性糖、丙二醛和脯氨酸含量相对都有所下降。说明在半干旱河谷地采用不同造林技术措施对于提高干旱地区的造林成活率、水分利用效率以及促进树木更好地生长具有明显的作用。

摘  要:
An afforestation experiment was carried out at the semi-arid valleys in Tibet to examine the effects of different afforestation techniques on the physiological and biochemical characteristics of Populus szechuanica var.tibetica leaves,the measures included covering stone,plastic film,straw,egg-tray,and using water retaining agent.The results showed that all the measures promoted the survival rate of afforestation in varying degrees.The relative water content and chlorophyll content in the leaves increased under the different measures,and the content of soluble sugar,malondiadehyde and proline in the leaves decreased,indicating that the application of different afforestation techniques played significant roles in improving the survival rate of afforestation,increasing water use efficiency,and promoting better growth of the trees in semi-arid valleys.
