从七十年代末期,世界上逐步开发出一系列茎叶处理除草剂品种,其中在我国农业上已应用的有拿捕净、稳杀得、盖草能、禾草克、苯达松、杂草焚、虎威等。了解植物对茎叶处理除草剂的吸收和影响因素,有助于正确使用除草剂。一、吸收部位 1.叶片叶片是吸收茎叶处理除草剂的主要部位。通常,叶面处理剂要求的雾滴密度比土壤处理剂及杀虫、杀菌剂大(见下表),低容量除草剂的良好覆盖面积为80%,而杀虫、杀菌剂为70%。
From the late seventies, the world has gradually developed a series of stem and leaf herbicide varieties, which have been used in China’s agriculture to take net capture, steadily get, cover grass can, grass grams, bentazon, weeds Burning, Tiger Granville and so on. Understanding plant uptake and influencing factors on stem-leaf herbicides helps in the proper use of herbicides. First, the absorption site 1. Leaf blade is the absorption of stems and leaves of the main parts of herbicides. Generally, the required droplet densities for foliar treatment are greater than 80% for low-volume herbicides and 70% for insecticide and fungicide compared to soil treatment agents and insecticides and bactericides (see table below).
