镇草宁(草甘膦)是近年来国内外新发展起来的一种广谱性萌后除草剂,它对许多一年生及多年生杂草均有较好的灭除效果,对茅草的防除效果也同样良好。但其灭茅效果受环境条件等多种因子的影响,例如,不同的气候条件或不同的施药期,效果是不同的。近两年来,我们就影响镇草宁灭茅效果的各种因子进行了一些试验观察,虽然这只是初步的,但希望能对今后进一步开展研究或使用这种新的除草剂提供一些参考。 Zhencao Ning (glyphosate) is a broad-spectrum post-emergence herbicide developed in recent years at home and abroad. It has good elimination effects on many annual and perennial weeds, and its control effect on thatch Same good. However, the effect of detoxification is affected by many factors such as environmental conditions, for example, different climatic conditions or different application periods, the effects are different. In the past two years, we have made some experimental observations on the various factors that affect the efficacy of phononol and demetonate. Although this is only preliminary, we hope to provide some references for further research or use of this new herbicide in the future.
