随着工农业生产和科学技术的发展,我国农田化学除草剂的研制和生产进展很快,化学除草的应用范围也不断扩大。为了减轻农业生产的劳动强度,我们从1970年起连续五年进行了水稻田化学除草的实践,初步掌握了几种除草剂的性能,在一定程度上控制住了杂草的发生。 With the development of industry and agriculture and the development of science and technology, the research and production of farm chemical herbicide has been progressing rapidly and the application range of chemical weed control has been expanding. In order to reduce the labor intensity of agricultural production, we conducted the chemical weed-controlling practice in paddy field for five years in succession from 1970, initially mastered the performance of several herbicides and controlled the occurrence of weeds to a certain extent.
