| 摘 要： | 豚草是世界性的恶性害草,造成巨大的农牧业损失和景观破坏.该文研究了豚草发生地土壤微生物的数量特征.结果表明:土壤微生物总数的峰值出现在8月,放线菌、细菌和真菌的数量峰值分别出现在7～9月.在8月和9月,豚草样地的土壤细菌、真菌和放线菌数量均低于对照样地,说明豚草对土壤微生物数量具有一定的抑制作用.三裂叶豚草对土壤微生物数量的抑制作用大于普通豚草.豚草的抑菌效应可为新药源、绿色农药等的开发提供参考.

| Abstract: | Ragweed is a worldwide vicious weed,which causes huge loss in agriculture,husbandry,and landscape.In this paper,the quantitative characteristics of soil microorganisms in a ragweed habitat were studied.The results showed that the peak of soil microorganism total number appeared in August,the peaks of soil actinomycetes,bacteria,and fungi appeared in July,August,and September,respectively.In August and September,the numbers of soil bacteria,fungi,and actinomycetes in ragweed plots were lower than those in co... |
