本文通过对春小麦五个不同熟期的品种籽粒灌浆进程,三年的观察资料,描述了春小麦籽粒灌浆的基本模式。结合松哈地区三年的气象资料,分析了高温逼熟的现象及其可能的原因:比较分析了不同类型品种间灌浆速度的差异。根据实验结果,从籽粒灌浆角度提出了适合松哈地区栽培的小麦品种的生态类型:穗茎节短,耐高温,前期抗旱,后期耐湿灌浆速度快的早熟、中早熟品种。
In this paper, the spring wheat grain filling process of five different maturity stages, three years of observation data, describes the basic pattern of spring wheat grain filling. Combined with three years of meteorological data in Songha region, the phenomena of high temperature ripening and its possible causes were analyzed: the differences of filling rates among different types of cultivars were compared and analyzed. According to the experimental results, the ecological types of wheat cultivars suitable for Songha region were put forward from the perspective of grain filling: early maturing and middle-early maturing varieties with short stem and ear, high temperature resistance, drought resistance in the early stage and fast wetting and filling in the late stage.
