光化学除草法国外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，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。电流除草法国外的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，? Photochemical herbicides France has succeeded in developing a photochemical herbicide that is applied to the fields of crops such as wheat and corn to automatically generate chemical reactions upon exposure to the sun and to kill weeds efficiently Do not damage crops. Current Scrapping Many scientists outside France have experimentally demonstrated that the sensitivity of plants to current depends on the amount of fiber and lignin contained in the plant.
