我国旱地作物种类较多,分布面广,草害十分严重。根据调查,麦子、玉米、大豆、棉花、花生、油菜、果树、蔬菜等作物田内草害面积占作物面积的44—72％。 为了进一步发展我国旱地作物化学除草,提出如下建议: 继续开发高效低毒的新一代除草剂 近年来由国外引进的高效低毒除草剂很多,如大豆田的普施特、麦田的甲黄隆、骠马,油菜田的高达克等。这些除草剂除了高效低毒以外,最大的特点是能够适应早地杂草种群的变化。为
There are many kinds of dryland crops in our country, with a wide distribution and very serious grass damage. According to the survey, grassland area of wheat, corn, soybean, cotton, peanut, rape, fruit trees, vegetables and other crops accounts for 44-72% of the crop area. In order to further develop the chemical weed control in dryland crops in our country, the following suggestions are made: Continue to develop a new generation of herbicide with high efficiency and low toxicity In recent years, there are many high-efficiency and low-toxicity herbicides introduced from abroad, such as Purst in soybean field, Horse, rape field of up to grams. In addition to the high efficiency and low toxicity of these herbicides, the biggest feature is the ability to adapt to the early weed population changes. for
