摘  要：
为探明基肥对银叶金合欢幼苗生长的影响,以广东省"碳汇林"造林工程常用的4种肥料作基肥,在整地挖穴时施入,苗木种植后的90d和180d分别测定幼苗的树高、地径、冠幅-生长量,试验结束时,取全苗分析苗木物质积累重量,用LA-S植物图像分析仪扫描分析苗木叶片生长情况。结果表明:幼苗高生长及冠幅生长对基肥出现明显差异性(P<0.05)的响应时段在0-90d,地径在90-180d;采用挪威进口复合肥、林木专用肥、发酵干鸡粪作基肥,其苗木树高、地径、冠幅的生长增幅、苗木物质积累、单叶面积及整株叶片面积均高于过磷酸钙作基肥处理,并以林木专用肥作基肥生长效果最优,其苗木树高、地径、冠幅的生长增幅以及干物质积累、单叶面积和整株叶片面积比对照净增9.73%、14.82%、14.04%、216.5%、41.5%和113.8%,达到显著差异水平(P<0.05)。

摘  要：
In order to understand the effect of fertilizer on the growth of Acacia podalyriifolia seedlings,by selecting 4 kinds of fertilizers,applied during the excavation of the ground preparation and commonly used in the‘carbon forest'plantation in Guangdong province,the height,the ground diameter and the crown width were measured at 90 d and 180 d after seedling planting.In the end of this experiment,the whole seedlings were used to analyze material accumulation,and the LA-S plant image analyzer was used to scan and analyze the seedling leaves growth.The results showed that,in response to the different fertilizers,the height and the growth of crown width had significant difference(P<0.05)in the 0-90 d,and 90-180 d for the ground diameter.Compare to other 3 kinds fertilizers,the seedling height,ground diameter,crown net growth,seedling material accumulation,single leaf area and whole leaf area were the smallest using.For superphosphate as fertilizer,and the effect of Forest Special Fertilizer was the best,and the growth of seedling height,ground diameter,crown width,dry material accumulation,single leaf area and whole leaf area increased by 9.73%,14.82%,14.04%,216.5%,41.5% and 113.8%,respectively(P<0.05).
