| 摘 要： | 通过对杭州市钱塘江北岸滨海地区黄化樟树使用长效复合铁肥,研究了樟树叶片主要因子变化规律.结果表明,各处理均减少了叶片的全磷含量,增加了叶片的过氧化氢酶、过氧化物酶、SPAD值、活性铁、全铁、全氮和全钾的含量,增加高低顺序为活性铁>过氧化氢酶>过氧化物酶>全钾>SPAD值>全铁>全氮.5 kg 肥料和7.5 kg 肥料发挥肥效迅速,5kg 肥料+25 kg 红土和7.5kg 肥料+25 kg 红土次之,5 kg 肥料+50kg 红土和7.5 kg 肥料+50kg 红土肥效发挥得最缓慢,在条件允许下,红土用量越多越好.叶片全磷含量为5kg 肥料>7.5kg 肥料,5kg 肥料+25kg 红土7.5kg 肥料+25kg 红土,5kg 肥料+50kg 红土>7.5 kg 肥料+50kg 红土,其余养分正好相反,在适宜的施肥料下,肥料越多,效果越好.不同取样时间养分变化规律性不强,仅SPAD值和活性铁变化规律一致,多数养分在8月较高;不同处理养分变化规律性不强;全磷与活性铁之间表现为拮抗作用,其余营养元素与活性铁之间表现为增效作用.

| Abstract: | The main factors causing the change of leaves of camphor-tree were studied after nourishing the chlorosis camphor-tree with a slow-releasing compound iron fertilizer in the coastal region in the north shore of the Qiantang River.Results indicate that compared with the control,the total P content in leaves is reduced in all treatments,but other nutrients in leaves increase in the order of active Fe> catalase> peroxidase > total K > SPAD value> total Fe > total N.5.kg fertilizer and 7.5.kg fertilizer exert ra... |
