拉斯柯发明了一种装在拖拉机上的电力除草器,它利用拖拉机输出的动力发电,由一把金属犁刀支撑。当探针碰触到比作物高的杂草时,电路接通,以5万瓦能量使杂草灼伤。制造这种装置的公司经理 W.D.戴科斯说,电能使细胞内含物沸腾、细胞灼伤破 Lasko invented an electric weeder mounted on a tractor that uses the power output from the tractor to generate electricity and is supported by a metal coulter. When the probe touches weeds that are taller than the crop, the circuit turns on and burns the weed with 50,000 watts of energy. W.D. Dekos, the company’s manager who makes the device, says that electrical energy can boil cellular contents and burn cells
