几年来,我们在‘机械化农业’和‘机农通报’上曾经报导过一些水田在排水状态下的机械化作业技术问题。但是,在长江流域以南雨水较多地区,由于自然条件的限制,常常要在灌水的情况下进行水田作业,因此,我们过去在东北和华北地区所取得的一些经验(如旱直播)就很难采用,需要找出新的方法和途径。几年来,经过南方各场职工的不断努力,在水稻水直播和灌水耕地方面已取得初步经验。为了更好地交流经验,发动群众智慧来解决这方面的技术问题,希望各场将水田机械化作业的经验总结出来。特别是水稻插秧、除草、收割等机械化作业,要继续进行试验研究。
In the past few years, we have reported some technical problems of mechanized operation of paddy fields under draining conditions in Mechanized Agriculture and Agronomy. However, due to the limited natural conditions in paddy fields south of the Yangtze River basin, paddy field operations are often carried out under irrigation. Therefore, some of the past experiences (such as direct seeding) we have gained in Northeast and North China Difficult to adopt, need to find new ways and means. In the past few years, through the constant efforts of various staffs in the South, preliminary experience has been obtained in direct watering and irrigation of paddy fields. In order to better exchange experiences and mobilize the wisdom of the masses to solve the technical problems in this respect, I hope that the experience of paddy field mechanization will be summed up. In particular, rice planting, weeding, harvesting and other mechanized operations, to continue the pilot study.
