[目的]研究人工复壮措施对乔木状沙拐枣叶片生长的影响。[方法]对乔木状沙拐枣林采取平茬、间伐处理,对比分析了同化枝表面积和生物量。[结果]不同定植年限下,乔木状沙拐枣同化枝表面积和生物量差异显著(P<0.01),林龄较大的当年同化枝活力较小;经平茬处理的乔木状沙拐枣林,保留株同化枝萌蘖能力明显增强,其中二次平茬最为突出;间伐对乔木状沙拐枣衰老有明显减缓作用,2 m×1 m间伐方式下乔木状沙拐枣同化枝表面积和生物量最大。[结论]人工复壮更新措施对于延缓塔里木沙漠公路乔木状沙拐枣林衰败,增强其活力有显著作用。
[Objective] The research aimed to study the effects of artificial rejuvenation measures on the growth of Juglans Callis. [Method] The stubble and thinning treatments on the jujube trees of Callistra japonicus were compared. The surface area and biomass of the shoots were compared. [Result] The results showed that there was significant difference in the surface area and biomass of assimilating branches (P <0.01) under different colonization ages, but less vigor in the same age branches when the age was larger. , The retained strain of assimilating branches increased significantly, of which secondary stubble was the most prominent. The thinning had a significant slowing effect on the age of ardimia convolvulus. Under 2 m × 1 m thinning, the surface area and biomass The largest amount. [Conclusion] The artificial rejuvenation and rejuvenation measures played a significant role in delaying the decline and enhancing the vitality of Arboretum jujube forests in the Tarim Desert Highway.
