电流除草法科学家们发现,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,高压电流能极大地损害杂草,而对农作物则通常无害,为此国外已研制出
Current weeding scientists have found that the sensitivity of plants to current depends on the amount of fiber and lignin contained in the plant. High-voltage currents can greatly damage weeds while they are usually harmless to crops. For this reason, foreign countries have developed
