我们从1976年开始连续四年进行了棉田化学除草的试验、示范和推广工作,取得了比较满意的结果。1978年和1979年全场化学除草面积占棉田总面积的一半以上,并推广到花生、早大豆等作物上。实践证明,化学除草剂的使用,有效地调剂了劳动力,避免了草、苗争光、争肥矛盾,节省了肥料;同时减少了因为人工锄草时剔除棉苗蔸间杂草而伤苗的现象,保证了棉苗密度,促进了棉花产量的提高。全场棉
Since 1976, we conducted tests, demonstration and popularization of chemical weed control in cotton fields for four consecutive years and achieved satisfactory results. In 1978 and 1979, the audience chemical weed-free area accounted for more than half of the total area of cotton, and extended to peanuts, soybeans and other crops.
