不同浓度生活污水对秋茄(kanadelia candel)幼苗生长的影响

The influence of different concentrations of domestic sewage on growth of seedlings of Kandelia candel

本文通过红树植物秋茄(kanadelia candel)幼苗在不同浓度生活污水中培养两个月,通过比较在不同浓度生活污水中秋茄幼苗生长的形态指标和生理指标差异,研究不同浓度生活污水对秋茄幼苗生长的影响。研究结果表明:不同浓度生活污水对秋茄幼苗的生长具有一定影响,低浓度的生活污水对秋茄幼苗的生长有促进作用,随着污水浓度增加这种促进作用加强,到中等浓度(40%左右)达到最大,而后随着生活污水浓度增加促进作用降低,最后出现抑制作用。本研究表明秋茄幼苗对生活污水的抗性较强,能耐受不同浓度生活污水的影响;同时表明红树植物对生活污水的适应能力较强,利用红树林湿地系统净化生活污水有一定可行性。试验结果为合理利用和保护红树林资源提供科学依据。

This paper Kandelia candel(kanadelia candel) seedlings are cultivated for two months in different concentration sewage, through the comparison of the different concentration of sewage mid autumn morphologic and physiological indexes of eggplant seedling growth differences, effects of different concentrations of domestic sewage on the growth of Tomato Seedlings in autumn. The results show that: it has certain influence on growth of different concentration sewage on Kandelia candel seedlings, promote the growth of low concentration domestic sewage Kandelia candel seedlings, with the sewage concentration increased the promoting effect to strengthen, to medium concentration(40%) reached the maximum, and with the sewage concentration increased role, finally appears to inhibit the effect. This study shows that the resistance of sewage Kandelia candel seedling is strong, can tolerate the effects of different concentrations of domestic sewage; at the same time that mangrove plants ability to adapt to the domestic sewage is strong, mangrove wetland system for sewage purification has certain feasibility. The results provide a scientific basis for reasonable exploitation and protection of mangrove resources.
