摘要：在玻璃网室中建立秋茄模拟湿地,分别用不同浓度的人工含油废水进行为期一年的每周两次定期排放,对照组(ＣＬ)用盐度１５‰的人工海水。人工含油废水对秋茄幼苗生长的影响如下:２００ｍｇ·Ｌ－１、４００ｍｇ·Ｌ－１和８００ｍｇ·Ｌ－１组的部分植株出现叶尖卷曲、叶缘有褐色斑点、叶片失绿等受害症状,８００ｍｇ·Ｌ－１组植株的受害症状出现的时间最早而且个体数最多;较高浓度的含油废水导致秋茄幼苗个体死亡,２００ｍｇ·Ｌ－１、４００ｍｇ·Ｌ－１和８００ｍｇ·Ｌ－１组的存活率依次为９５．９%、８５．２%和５９．２%。５０ｍｇ·Ｌ－１含油废水对秋茄幼苗的生长有促进作用,表现为生物量、茎高和茎径的年增长量极显著高于对照组;１００ｍｇ·Ｌ－１和２００ｍｇ·Ｌ－１含油废水对秋茄幼苗的生长无明显不良影响,表现为２００ｍｇ·Ｌ－１组生物量、茎高和茎径的年增长量与对照组比无显著差异,１００ｍｇ·Ｌ－１组植株仅茎高年增长量显著高于对照组;较高浓度的含油废水则使秋茄幼苗生长受到显著抑制,表现为４００ｍｇ·Ｌ－１组生物量和茎高的年增长量显著或极显著低于对照组,８００ｍｇ·Ｌ－１组生物量、茎高和茎径的年增长量显著或极显著低于对照组。表明秋茄幼苗对低浓度含油废水有一定的?
Kandelia candel simulated wetland was set up in a greenhouse. The system consisted of three subsystems, one-year old K. candel seedlings, sediment and water. The synthetic oily wastewater with five various concentrations, i.e. 50 mg·L-1, 100 mg·L-1, 200 mg·L-1, 400 mg·L-1, 800 mg·L-1 and 15‰ artificial seawater (CL i.e. control) had been discharged into wetland twice a week for one year. The effects of oily wastewater on the growth of K. candel seedlings are as follows; Applied with oily wastewater at concentrations of 200 mg·L-1, 400 mg·L-1 and 800 mg·L-1, some seedlings expressed damage symptoms including curling of the leaves, chlorosis, with reddish pigmentation etc. To the 800 mg·L-1 group, seedlings expressed damage symptoms firstly and the number was the most. The survival percentages of seedlings applied with 200 mg·L-1, 400 mg·L-1 and 800 mg·L-1 oily wastewater were 95.92%、85.18% and 59.25% respectively. Discharge of oily wastewater at lower concentration could stimulate the seedling growth of K. can-del. As to the 50 mg·L-1 group, yearly increment values of stem height, stem diameter and biomass were higher than CL with very significance level. Treated with 200 mg·L-1 oil wastewater, yearly increment values of stem height, stem diameter and biomass were close to CL. To the 100 mg·L-1 group, yearly increment value of stem height was higher than CL significantly. As to the 400 mg·L-1 and 800 mg·L-1 groups, plant growth was obviously inhibited. As a conclusion, K. candel had resistance and adaptability to oily wastewater, but oily wastewater at higher concentration would be harmful to K. candel.
