以肥除草法据国外生物学家试验研究,在杂草丛生的田地里,施用一种特制的氮基酸肥料,不仅能够杀死某些杂草,而且还能促进农作物的生长。光化学除草法目前已有一种光化学除草剂在美国上市。将其施用到小麦、玉米地里,遇到阳光就会自动发生化学反应,将杂草杀死,而农作物则安然无恙。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,高压电流能有效地损害杂草的生物结构,进而使其枯萎死亡。为此,一些国家已研制成功了可安装在农用机械上的电流除草装置,并用高
Fertilizer Weeding Law According to experimental studies by foreign biologists, applying a special nitrogen-based fertilizer to weedy fields can not only kill certain weeds but also promote the growth of crops. Photochemical Weeding There is currently a photochemical herbicide listed in the United States. Apply it to the wheat, corn fields, in the face of the sun will automatically chemical reaction, the weeds to kill, while the crops are safe and sound. Current Scrapping Many scientists outside France have shown through experiments that the sensitivity of a plant to current depends on the amount of fiber and lignin contained in the plant. High-voltage currents can effectively damage the weed’s biological structure and cause it to wither and die. To this end, some countries have successfully developed a current herbicidal device that can be installed on agricultural machinery and used high
