The essential micronutrients to plants and phytotoxicity of toxic heavy metals are not related merely to the total concentrations but depend on their availability in soils 摘要土壤中植物必需的微量营养元素的供给以及有害元素的毒性大小并不仅仅与元素的总量有关，而取决于元素的有效性。

The results showed that 89 . 58 % control effect could be achieved with 35 % endosulfan ec exhibited slight phytotoxicity ; 40 % omethoate ec behaved longer residual duration ; insecticide resistance of 2 . 5 % cyhalothrin ec was reported , and 48 % chlorpyrifos ec diluted by 10 times was recommended therefore 结果表明： 48 %乐斯本乳油稀释10倍时防效可达89 . 58 % ， 35 %赛单乳油有轻微药害， 40 %氧化乐果乳油残效期长，建议防治中使用10倍的48 %乐斯本乳油。

In this paper , kandelia candel ( l . ) druce hypocotyls were cultivated in sand and treated with 15 % seawater for 60 days under laboratory conditions . the influence of increasing concentrations of napthalene and pyrene ( 0 , 0 . 1 , 1 and 10mg / l ) on hypocotyl germination and growth , photosynthesis metabolism , water metabolism and membrane protection system were observed to inquire into the ecophysiological responses of mangrove k . candel to pahs phytotoxicity . moreover , the concentration and distribution of parent polycyclic aromatic hydrocarbons ( pah ' s ) in surface sediment , underground root and leaf residue of mangroves in jiulong river estuary ( fugong , north and south shores of haimen island , baijiao ) , neighbouring xiamen western harbour ( dong islet ) and dongzui harbour ( fenglin ) were examined 在实验室条件下，分别以0 . 1 、 1和10mg l的萘( nap )和芘( pyr ) 3个梯度浓度组级砂基培养秋茄( kandeliacandel ( l . ) druce )幼苗，培养基盐度15 ，培养期60d ，以不加pahs为对照，分析了nap和pyr对红树植物秋茄幼苗的生长、光合代谢、水分代谢以及膜保护系统的影响，探讨pahs对红树植物秋茄的的生理生态效应及植物性毒害( phytotoxicity )的机理。
