| 摘 要： | 研究表明树体的营养状态与柑桔炭疽病菌由潜伏状态转为活跃状态与寄主发病有关。树体健壮,即叶片全磷、全钾含量高,秋冬季节含氮化物积累多则发病较轻。经复壮措施处理后,重病树体的生长势能逐渐回升。

| Abstract: | The nutri ture in vivo of citrus (Citrus unshin Marc.) is relative to anthracnose development, ie. the pathogen, Colletotrichum gloeosporioides from quiescence turns to vigor leading to formation of anthracnose lesions. The disease incidence will be lower while vigorous growth (le. the total phosphorus and kalium in leaves is higher, in Autumn and winter the nitrogenous compounds in leaves accumulate more) After some juvenescent treatment to tree with higher disease incidence, the growth potential can recover. |
