| 摘 要： | 对苏北杨树黄化病发生情况的调查、分析结果表明：苏北杨树黄化病感病区域内发病情况严重,感病指数达63%。同时,随着发病程度的增加,其苗高、地径等生长指标显著下降,最高降幅达63.7%和56.51%,严重影响了苗木质量。对土壤分析显示,土壤中Mg、Zn元素的含量与感病指数、苗高、地径存在着典型相关性。严重黄化区域土壤中Mg、Zn含量均与正常区域有显著差异,表明土壤中Mg、Zn元素可能是苏北杨树苗木黄化的重要影响因素。

| Abstract: | The article analyzed the effects of disease indexes of poplar yellows on the height of seedlings and the base diameter based on the investigation in the northern Jiangsu.The results showed that the poplar tree yellows occurred seriously in heavily diseased area of the northern Jiangsu,and the disease index reached 63%.At the same time,the height of seedlings and base diameter decreased significantly with increasing in disease index,and the highest decreasing range reached 63.7% and 56.51% respectively,which... |
