草甘膦属于强内吸,非选择性除草剂。长期以来,草甘膦都采用高量(用水量为50～75公斤/亩)进行茎、叶喷雾。贵州山区,茶园、果园水源缺少地方,草甘膦除草采用高量喷雾增加不少负担。为此,我们根据草甘膦强内吸特点,并参考有关资料介绍,将高量喷雾改为中量喷雾(25公斤/亩药液)和低量喷雾(10～12.5公斤/亩药液),可提高工效2～4.8倍,大大节约人力,为草甘膦的广泛使用提供了有利条件。 另外我们还对草甘膦除草不中耕,对土壤理化性的影响,草甘膦除草对苹果品质的影响进行了试验。现将试验结果报道如下。
Glyphosate is a strong internal absorption, non-selective herbicide. For a long time, glyphosate has been used in high volume (water consumption of 50 ~ 75 kg / acre) stems and leaves spray. Guizhou mountainous areas, tea gardens, orchards lack of water, glyphosate weeding with high volume spray to increase a lot of burden. Therefore, based on the strong internal absorption characteristics of glyphosate and referring to relevant information, we changed the high-level spray to the medium-spray (25 kg / mu) and low-volume spray (10-12.5 kg / mu) Improve work efficiency 2 ~ 4.8 times, greatly saving manpower, provided favorable conditions for the widespread use of glyphosate. In addition, we also test the effects of glyphosate weeding without tillage, soil physical and chemical properties, the effect of glyphosate weed control on apple quality. The test results are reported below.
