在毛主席革命路线指引下,在“农业学大寨”群众运动的推动下,我场1969年开始试验稻田化学除草,以后逐年扩大使用面积,去年全场12000亩稻田全部实行化学除草,并广泛开展了群众性的科学实验活动。1975年以来,我们在积极开展化学除草的同时,对稻田杂草的综合防除问题,做了一些调查研究。经过两年来的初步实践,认识到:要从根本上解决草害问题,必须贯彻“以防为主,综合防治”的方针,从多方面采取措施。首先必须掌握主要杂草的生物学特性和发生危害规律,这是搞好综合防除的前提,其次要在充分运用各项农业技术措施,并 Under the guidance of Chairman Mao’s revolutionary line and with the mass movement of “Learning from Dazhai in Agriculture”, we began to experimentally weed out chemical weeds in paddy fields in 1969 and expanded the area to be used year by year. Last year, 12,000 mu of paddy fields were completely weeded by chemical weeding and extensively Carried out mass scientific experiments. Since 1975, while actively carrying out chemical weeding, we have done some investigations and studies on the comprehensive prevention and control of weeds in rice fields. After two years of initial practice, I realized that to fundamentally solve the problem of grass and pests, we must implement the principle of “prevention first and comprehensive prevention and control”, and take measures in many aspects. First of all we must master the biological characteristics of the main weeds and the law of occurrence of harm, which is to do a good job of comprehensive prevention and control of the premise, and secondly to make full use of various agricultural technology measures and
