延边地区地处吉林省东部山区,是寒冷稻作区。无霜期100～140天左右,年平均气温5℃左右。由于受低温影响,加之技术措施不当,水稻单产一直不高不稳。为探讨水稻高产体制,在初步总结群众丰产经验的基础上,从1972～1976年在延边农学院进行了水稻高产栽培试验(亩产千斤指标)。本文主要是总结和分析几年来的高产栽培试验结果,并结合国内外有关研究资料,提出寒冷地区水稻亩产千斤的栽培体制的粗浅看法。由于水平所限,难免有不当之处,望有关方面同志的批评指正。
Yanbian area is located in the eastern mountains of Jilin Province, is a cold rice area. Frost-free period of about 100 to 140 days, the annual average temperature of about 5 ℃. Due to the impact of low temperature, coupled with improper technical measures, rice yield has been low and unstable. In order to explore the high-yielding rice system, based on the preliminary summary of the experience of the masses, a high-yielding cultivation experiment (yield index) was conducted from 1972 to 1976 in Yanbian Agricultural College. This paper mainly summarizes and analyzes the results of high-yielding cultivation experiments over the past few years. Based on relevant research data at home and abroad, this paper puts forward the superficial view on the cultivation system of rice per mu in cold regions. Due to the limited level, it is inevitable that there will be any improper place and hope the comrades concerned will criticize and correct it.
