【摘要】 为了探讨优质小麦在关键技术集成后的灌浆特性,在大田试验条件下,利用不同水平的密度、种植方式和EM制剂,采用裂区设计,较系统地研究了优质小麦品种小偃503的灌浆特性。结果表明,各处理籽粒干重均呈"S"型曲线;密度和种植方式是影响小麦灌浆特性较大的两个因素;小麦灌浆参数与粒重关系密切。更多还原

【Abstract】 To discuss the properties of grain-filling of Xiaoyan 503 in the integrated experiment with key (techniques), the writer studied it systemicly with the different densities, the planting ways and EM reagent by split design in the field. The results showed that the dry-weight of grain existed "S" curvilinear in every (treatment). The density and planting way were two main factors affecting the filling of wheat. The filling paramerter was closely related to the grain weight.更多还原
