稻田使用化学除草剂,有利于促进粮食生产,且节约大量势力,是实现农业现代化的一项重要措施。但是化学除草剂施用后,对稻田土壤中的生态平衡和土壤肥力的影响,是值得研究的一个问题。本试验探讨杀草丹对稻田土壤微生物及生物酶活性的影响。杀草丹(又称稻草完)是我省化工研究所1971年合成的一种内吸传导选择性除草剂,国内外已广泛用于稻田化学除草,深受欢迎。杀草丹纯品为无色油状液体,难溶于水,能溶于苯、酒精等有机溶剂,它的活性成分是:
The use of chemical herbicides in paddy fields is conducive to promoting grain production and saving a great deal of power. It is an important measure to realize agricultural modernization. However, the effects of chemical herbicide on the ecological balance and soil fertility of paddy soils are worth studying. This experiment explored the effect of herbicide Dancaodan on soil microbial and enzyme activity in paddy soil. Kill grass Dan (also known as straw end) is a chemical industry in our province in 1971 synthesis of a selective conduction herbicide, both at home and abroad have been widely used in chemical weed control in paddy, the popular. Dancao Dan pure product as a colorless oily liquid, insoluble in water, soluble in benzene, alcohol and other organic solvents, and its active ingredient is:
