干旱沙区杨树抗旱栽植研究

Studies on Poplar Tree Transplanting in Sandy Dryland Regions

在干旱沙区栽植杨树,采用大穴深栽、汇集地表径流、高分子吸水剂等技术措施,可使杨树成活率达到92％,并比较研究了与常规栽植对杨树的成活、生长和体内水分平衡状况的影响。生长量比常规栽植提高三倍,造林一次成功。

By means of making a bigger itch to collect surface runoff, plus with large-molecular water absorbing agents, poplar tree transplanting in dryland sandy soil achieve a survival rate of 92%. Survival rate, growth rate and water balance of the plant were compared with the traditional method. Growth rate was increased by 3 times comparing with conventional planting.
