The killing effect on oncomelania hupensis by lixivium of pterocarya stenoptera , nerium indicum , rumex japonicus and their mixture was studied . differences of the snails mortality were studied also . the three kinds of plant material could kill the snail effectively both in spring and in autumn . but the mortality was different when the experiment is done in different seasons or with different lixivium . the effect in spring was better than that in autumn . n . indicum was the most effective among the three kinds . the effect by mixture was better than that by unitary material , and the effect by the mixture of the three kinds was better than that by two kinds . the variance analyses showed that the experiment could be modified , and some ingredients concentration in mixed lixivium could be reduced . the experiment was valuable in enhancing the power of killing the snail and saving plant material 對楓楊、夾竹桃和土大黃以及它們的組合水浸液的滅螺效果作了比較研究,結果表明: ( 1 )滅螺效果均隨水浸液濃度的增高而增強; ( 2 )這3種植物材料及其組合水浸液的滅螺效果都是春季比秋季好; ( 3 )組合水浸液的滅螺效果比單一植物材料水浸液的滅螺效果好; ( 4 )方差分析的結果說明植物材料組合水浸液滅螺在保證滅螺效果的前提下,還可以適當降低組合水浸液中的濃度.以上結論對提高植物材料的滅螺效率和節省植物材料的使用量有著重要的意義,同時也為組建植物滅螺群落提供了有益的參考

Ammonifiers in suzhou creek can not use inorganic nitrogen and carbamide as nitrogen source ; additional carbon source and garbage lixivium have little influence on ammonifiers growth ; high content of salt and low temperature restrain ammonifiers growth ; alkalescent condition has little influence on ammonifiers , but acidic condition restrain ammonifiers growth ; the biomass of ammonifiers are not necessary correlated with the function of ammonifiers , adding glucose with 1g / l content into the water sample obviously promote the growth and function of ammonifiers . physiological groups of bacteria play significant role in the translation and 蘇州河的氨化菌無法利用無機氮和尿素作為氮源;在營養條件充足時添加額外c源和富含有機物的垃圾浸出液對氨化菌的生長基本無影響;高鹽度和低溫抑制氨化菌生長;堿性條件對氨化菌的生長影響不大,酸性條件對氨化菌生長具有抑制作用;氨化菌生物量的消長與轉氨活性之間不存在必然聯系, 1g / l的葡萄糖對蘇州河水樣中氨化菌的數量和轉氨功能具有明顯的促進作用。
