He added that some farmers also believe burning stalks increases the fertilising capabilities of the field& though previous research has shown no significant effects. 他还说,一些农民认为,燃烧秸秆能增加田地里的肥力,尽管过去的研究已经显示,燃烧秸秆并没有显著的效果。
Even weaker members of the species have a compensating trait in evolutionary terms& huge testicles which increase their chances of fertilising a female. 但物种中即便“体质”较弱的在进化过程中也了补偿性特质,即巨大的睾丸,特征会增大它们与雌性屎壳郎交配的几率。
