摘　　要：从寒地生态特点出发，探讨播种插秧时期对水稻产量和米质的影响。寒地现有主栽品种，当外界气温稳定通过5-6℃，适期早播种，有利于育成足龄壮秧和适期早插，适宜播种期为4月10-20日。当外界气温稳定通过13-15℃，为适宜插秧期，一般年份在5月15-25日，最晚不超过5月末，插秧期推迟产量品质下降。According to the cold ecological characteristics,effect on rice yield and quality of rice by seeding and planting period,heading period and the harvest period were studied. When the outside temperature stability went through 5-6℃ ,the existing cold grown varieties should be sowed early, which would conducive to breeding aged and strong seeds and inserting plants at earlier stage. Appropriate sowing time was from April 10^th to 20^th;When the outside temperature stability went through 13-15℃ ,appropriate planting period was from .May 15^th to 25^th ,which of the latest was not more than the late of May,postponing planting period would deduce the decline of both the yield and quality.
