在毛主席革命路线指引下,在农业学大寨的群众运动中,遵照毛主席“农业的根本出路在于机械化”的教导,我场广大机务人员破除迷信,解放思想,急农业之所急,想农业之所想,大胆创新,自制成功机动喷雾机,为大面积旱田化学除草创造了有利条件。去年我场用自制机动喷雾机喷施2,4-滴丁酯防除麦田杂草8,615亩,效果良好。据调查,我场旱田杂草分布密度,最高亩达265万株,一般为75万株左右;杂草植株高度最低20～40厘米,最高达135厘米。由于杂草分布密度大,根深、株高、叶茂,和农作物 Under the guidance of Chairman Mao’s revolutionary line, in the mass movement of learning Dazhai in agriculture, in accordance with Chairman Mao’s “fundamental road to agriculture lies in mechanization,” the majority of our field crew get rid of superstition, emancipate their minds and urgently urgently need agriculture. Agricultural thought, bold innovation, self-made mobile sprayer, for large areas of dry chemical weeding has created favorable conditions. Last year, my field with homemade mobile spray 2,4-D butyl ester control 8,615 acres of wheat weeds, the effect is good. According to the survey, we field distribution density of weeds, up to 2.65 million acres, usually about 750,000; weeds the lowest height of 20 to 40 cm, up to 135 cm. Due to the density of weeds distributed, root depth, plant height, leafy, and crops
