摘要: 通过连续5a的滴灌节水造林试验, 初步得到: 在干旱区戈壁和移动沙丘地带造林, 应用滴灌节水技术, 较地面大水漫灌节水70%以上; 苗木成活率平均可达96.2%, 保存率平均达93.4%, 年均生长量达40cm以上; 5a后的积沙总量为0.58m3·株-1(或每穴)。在试验的基础上, 系统地分析了滴灌节水技术在干旱区戈壁、沙丘地带造林中应用的可行性和重要性, 并对应用效果和应用过程中存在的问题进行了较为深入的探讨, 认为: 在西部干旱沙区因地制宜地推广滴灌节水型生物治沙技术, 是沙区治理、改善局部生态环境的一条重要途径。

Abstract: The experiment on afforestation with drip irrigation for five years showed that compared with flooding irrigation the water-saving technology of drip irrigation can save water more than 70%; the survival rate of nursery stock can be 93.4% and the survival rate of young trees can be 96.2%; also the annual growth of the nursery stock can be more than 40 cm. Five years later, the amount of accumulating sand can be 0.58 m3 per tree. It was proved that the drip irrigation technology has feasibility and importance for afforestation in Gobi and sand dune areas, and the popularizing of the technology by adjusting measures to local conditions is a new approach for controlling sand and improving eco-environment in the arid desert area of western China.

Key words: sand control with biological measures, drip irrigation, experimental analysis
