1.光化学除草法 科学家已经成功地研制出一种光化学除草剂,将其施用到小麦、玉米等农作物的地里时,一遇到阳光,就会自动产生化学反应,可高效率地把杂草杀死,而不损害农作物。 2.电池除草法 许多科学家通过试验证明,植物对电流的敏感程度,取决于植物中所含纤维和木质素的多少,强电流能极大地损害杂草,而对农作物通常无害。为此有的国家已研制出一种可安装在农业机械上的电流除
1. Photochemical weeding method Scientists have successfully developed a photochemical herbicide, when applied to the ground of crops such as wheat, corn, etc., a sunlight, it will automatically generate chemical reactions, weeds can be efficiently Kill, without damaging crops. 2. Battery weeding Many scientists have shown through experiments that the sensitivity of plants to current depends on the amount of fiber and lignin contained in the plant. High currents can greatly damage weeds and are generally not harmful to crops. For this reason, some countries have developed a current that can be installed on agricultural machinery
