【摘要】 为研究气候变化背景下冬小麦最佳播期、播种温度等指标,在2007和2008年郑麦366分期播种试验的基础上,利用相关分析、最小显著差数等方法对冬前积温、小麦生长及产量构成进行了研究,得出最佳播期、冬前积温以及达到壮苗标准的分蘖数和LAI(叶面积指数)等适宜指标。更多还原

【Abstract】 In order to discuss the indexes as suitable sowing date, sowing temperature, et al under climate changing background, the paper researched accumulated temperature, wheat growing condition and yield structure based on interval sowing tests in 2007 and 2008 for Zhengmai66 by methods of correlation analysis and least significant difference. suitable indexes for wheat such as suitable sowing date, accumulated temperature before overwintering, tiller number for strong seeding, LAI were finally achieved.更多还原
