摘要
调查和分析表明,重庆市山茶花(Camellia japonica L.)黄化病的成因是土壤有机质严重缺乏,土壤过酸、瘦导致土壤和植株缺铁症。植株体内锰含量过多,使Fe^(3+)不能还原为具有生理活性的Fe^(2+),更加剧了植株的黄化。施用有机铁可迅速改变山茶花黄叶的急性症状。
Investigations showed that deficiency of iron in soil and plant causedby deficiency of organic matter in soil and over acidity of soil wereattributed to the disease of Camellia japonica L.of Chongqing.The extremehigh level of manganese in plant inhibited transformation of Fe^(3+)into Fe^(2+)and intensified the disease.Organic iron applied through soil or lesves incompany with other cultivated techniques would prevent and control thedisease.
