摘　　要：为充分发挥黑龙江省的气候资源优势,探求玉米种植新模式,采用黑龙江省富裕县2005—2014年6—9月气温、辐射、降水等逐日、逐小时数据及对应的玉米生育期和2014年玉米穴盘大苗移栽分期播种资料,分别分析了移栽和直播玉米的七叶—拔节、拔节—抽雄、抽雄—乳熟、乳熟—成熟各生育期内的气温、辐射、降水。结果表明:移栽玉米比直播玉米生育期总天数增加10天,各生育期平均提前10天,热量利用率、辐射利用率、降水利用率、光温气候生产潜力分别提高21%、23%、27%、47%。玉米穴盘大苗移栽,使玉米各生育期内的光、热、水资源得到重新配置,气候生产潜力得到大幅提高。The paper aims to seek new maize planting patterns to bring climatic resource into a full play in Heilongjiang. Based on meteorological data（e.g. the temperature, precipitation and t radiation data） from Juneto September during maize growing season and the data of corresponding maize growth periods from 2005 to2014 in Fuyu, Heilongjiang, the temperature, radiation and precipitation data were analyzed from seven leavesstage to jointing stage, jointing stage to tasseling stage, tasseling stage to milky maturity stage and milkymaturity stage to maturity stage. The results showed that： the growth period of transplanting maize was 10 daysmore than that of direct seeding; all growth periods of maize were 10 days ahead of schedule; the utilization rateof heat, radiation, and precipitation increased by 21%, 23%, 27%, respectively; the production potential oflight-temperature increased by 47%. The transplanting maize by tray made the light, heat and water resourcesre configure in each growth period. The climate productive potential was greatly improved.
