摘要/Abstract

摘要： 通过比较国内外多种积温计算方法造成的结果差异,推荐一种有较强生物学意义和普适性的积温计算方法,并以此计算了不同播期、不同品种、不同密度以及不同水肥管理条件下夏玉米各生育阶段,从出苗到各叶片完全展开以及各叶片生活期的积温.讨论了影响植株及叶片生长发育期积温稳定性的主要因子,并模拟了单株出叶速度与出苗后温度累积以及叶片生活期积温需求与叶龄的定量关系.

Abstract: A growing degree-day(GDD)calculation method was recommended by comparing several popular used GDD calculation equations. The GDD between different development stages, from emergence to each leaf appearance and during the lifetime of each leaf,were calculated for summer maize with the field treatments differed in cultivars, plant density, sowing dates, water and fertilizer supplying levels. Factors influencing the stability of GDD were discussed,and simulation equations to predict the leaf development were fitted based on the field observed data.
