| 摘 要： | 本文研究了在晚播(10月21日播种)条件下,不同冬小麦品种籽粒灌浆进程模型及灌浆特性与粒重、籽粒含水量的关系.结果表明:晚播小麦灌浆期间籽粒子物质积累以logistic曲线递增,灌浆速度的变化为单峰曲线,籽粒含水量呈直线下降.晚播小麦的灌浆速度上升快、下降早、峰值高、时间短,灌浆中后期的油浆速度与粒重呈显著正相关.因此.在生产中应采取适当的栽培措施,提高其灌浆速度,特别是促进中后期的灌浆速度以及注意选用灌浆速度快,尤其是中后期灌浆速度快的品种.

| Abstract: | The paper studies the model of course of milking of the grains , the relationship between the characteristics of being in the milk of the grains and grains weight , water content of grains among different winterwheat varieties on condition of sowing late (sowed on 21, October). The results showed that during the filling stage of late-sown wheat, the accumulation of dry material increased progressively by the logistic curve, the change of the speed of milking was the curve of single peak value , and water content of grains decreased by the line. The speed of milking of late-sown wheat increased quickly, decreased early and was of high peak value, and short time. During the middle and late period of milking , its speed was positively correlated with grains weight remarkably. Thus, during the period of production, correct cultivation measures should be taken to increase its speed of milking , especially during the middle and late period . And, the variety of milking quickly , especially quickly during the middle and late period should be paid attention to choose. |
