一、水稻机械化旱直播栽培的简要回顾水稻旱播作为一种抗旱种稻的措施,过去在群众中早就有之。建国以来,随着半机械化、机械化农具的推广,水利工程的不断完善,经过五十年代我省科研、技术推广、生产单位和国营农场的多年试验、总结,旱播方法被研究、提高成机械化旱直播栽培技术,并根据不同生产水平和土地条件,形成浅覆土播种、深覆土播种和地面播种三种机械播种方法,同时又积累了翻地、整地、筑埂、收割、脱谷和精选等机械化作业经验, First, a brief review of dry cultivation of rice mechanization Dry rice as a drought-resistant rice measures in the past in the early part of the masses. Since the founding of the People’s Republic of China, with the promotion of semi-mechanized and mechanized farm implements and continuous improvement of water conservancy projects, after years of experiments and scientific research in our province in scientific research, technology promotion, production units and state-owned farms, the method of dry seeding has been studied and increased to mechanization According to different production levels and land conditions, three kinds of mechanical sowing methods such as shallow soil sowing, deep soil sowing and ground sowing were formed. At the same time, land reclamation, land preparation, building sowing, harvesting, threshing and selection Such as mechanized operation experience,
