- 摘要:
- 于2008年调查了天津城区法桐叶烧病与树龄、光照的关系及其消长动态。结果表明：法桐叶烧病发病初期在5月中旬，5月下旬到7月中旬为缓慢发病期，7月下旬直到10月底病害进入发病盛期；环境光照对病害发生轻重有显著影响，向阳面树体发病程度平均病情指数41.66%明显重于背阴面的树体平均病情指数13.77%；不同树龄的树体病株率差异明显，在发病较轻的背阴面，严重度病情指数差异不明显，在发病严重的向阳面随树龄增加病情指数呈增长趋势。
- Abstract:
- Platanus acerifoliaAit.Wild leaf scorch disease occurrence trend and environmental light intensity or age of tree impact on it were investigated in 2008.The result showed that Platanus acerifoliaAit.Wild leaf scorch disease started occurring at mid-May，the disease developed slowly during later-May to mid-July and progressed faster from later-July，Platanus acerifolia?Ait.Wild leaf scorch disease spread evidently bad during August to later-October.Environmental light intensity had influenced heavily to the disease indices.The diseased indices at the sun41.66%were evidently higher than that of at sunless13.77%.Diseased tree percentage had evidently difference to different tree’s age，the disease indices at sunless had not evidently difference.The disease indices had increased with increment of tree-age at the sun.
