material variance
解釋
材料差異-
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 -
