原平县东营大队,耕种着1,100亩水稻。由于稻田杂草种类多、数量大、繁殖快,往往发生草荒,影响着水稻产量的提高。近年来,我站在该大队稻田试验推广化学除草。方法是:每亩用25％可湿性除草醚0.8-1斤,或除草醚0.8斤和25％可湿性扑草净0.05斤混合,再拌过筛细湿土40斤,堆闷5小时。当本田插秧后7-10天,秧苗已返青,开始生长,杂草处于幼芽阶段,提前把水放到1-2寸深,均匀撒施毒土,保持水
Dongping Battalion Pingyuan County, cultivating 1,100 acres of rice. Due to the large number of weeds in paddy fields, large numbers and rapid propagation, grassland shortage often occurs, which affects the improvement of rice yield. In recent years, I stood in the brigade paddy field experiment to promote chemical weeding. The method is as follows: 0.8-1 kg of 25% wettable weed killer per acre or 0.8 kg of weeding ether and 0.05 kg of 25% wettable prometryn are mixed with 40 kg of fine wet soil, and the pile is bored for 5 hours. When Honda transplanting 7-10 days after the seedlings have returned green, began to grow, weeds in the bud stage, ahead of the water into the 1-2-inch deep, uniform soil poisoning, keep the water
