| 摘 要： | 沙枣（Elaeagnus angustifolia L．）作为有重要价值的燃料能源林树种，平茬是其利用的主要途径。研究了沙枣距地面0cm、5cm、10cm^3种高度平茬后的年生长变化及萌条的数量与质量。结果表明，沙枣丛高7、8、9三个月生长最快，3种平茬处理下丛高年生长量分别为147．84、145．88、136．04cm，极显著大于未平茬丛高年生长量。比较萌条的高径生长指标，发现距地面0cm平茬〉距地面5cm平茬〉距地面10cm平茬；而萌条总数：距地面10cm平茬〉距地面5cm平茬〉距地面0cm平茬。

| Abstract: | Elaeagnus angustifolia L.has important value as energy resources plant.The main way to utilize Elaeagnus angustifolia L.is stumping.The annual increments,quantity and quality of coppice shoot of Elaeagnus angustifolia L.were studied at the cutting heights of 0 cm,5 cm and 10 cm.The results showed that cluster height of Elaeagnus angustifolia L.grew fastest in July,August and September.Annual increment of cluster height was 147.84 cm,145.88 cm and 136.04 cm respectively under three stumping treatments,which ... |
