摘　　要：为探明相同积温条件下不同熟期玉米品种的产量和品质表现,通过在双城地区6个不同熟期的玉米品种收获期的茎秆含水量、籽粒含水量、籽粒产量等综合比较,结果发现宏晨788是适宜机械直收籽粒、秸秆粉碎还田并且产量较高的玉米品种,推断选择所需积温比当地实际积温小300℃的玉米品种有利于降低收获时的茎秆含水量和籽粒含水量,为本地区宜机收玉米品种的选择提供参考。In order to explore the yield and quality performance of maize varieties at different maturity stages under the same accumulated temperature condition,we comprehensively compared the stem water content,grain water content and grain yield of six maize varieties at different maturity stages in Shuangcheng,Harbin.The results showed that Hongchen 788 was a maize variety suitable for mechanical direct grain harvesting,straw crushing and returning to the field with high yield.We concluded that the selection of corn varieties whose required accumulated temperature was 300℃lower than the actual local accumulated temperature was conducive to reducing the stem water content and grain water content during harvest,which provided a reference for the selection of suitable corn varieties for local harvest.
