根据我省水稻生产发展规划,到本世纪九十年代水田面积要在目前500万亩左右的基础上,增加一倍。扩大水田的潜力主要在我省的低洼易涝地区。这些地区一般存在春旱缺水,迫切需要省水种稻的栽培技术。我国北方稻区的京、津一带,在水稻旱种方面已有报道。我们课题组1977～1981年在我省轻碱地进行水稻机械化旱种及化学除草技术研究,已总结出成套的水稻旱种栽培技术,并在吉林中西部盐碱地区累计4000多亩面积上示范成功,经省鉴定决定在生产上积极示范推广。但在黑土地上还缺乏大面积中间
According to our province’s rice production and development planning, by the 1990s the paddy field area should be doubled on the basis of the current 5 million mu. The potential for expanding paddy fields is mainly in the low-lying flood-prone areas in our province. In these areas, drought and water shortage generally exist and there is an urgent need for water-saving cultivation techniques. China’s northern rice in Beijing, Tianjin area, in the dry cultivation of rice has been reported. Our research group from 1977 to 1981 in our province light alkaline rice dry mechanized farming and chemical weeding technology has been summed up a complete set of rice dry cultivation techniques, and in the central and western regions of Jilin, a total area of more than 4,000 acres of demonstration success , The provincial appraisal decided to actively demonstrate the promotion of production. But there is still a lack of large areas in the black land
