摘  要:
为探讨小麦新品种周麦23号的高产优质配套栽培措施,采用三因子二次正交旋转组合设计,研究了播期(X1)、播量(X2)、追肥量(X3)对周麦23号主要农艺性状和品质特性的影响。结果表明,周麦23号的株高主要受播期影响,在10月21日播种时,株高最低(80.7 cm),10月10日播种植株最高(90.27 cm)。产量主要受播期、播量和追肥量的共同作用,建立的产量模型:Y=10 660.49-520.18X1-233.93X3-166.38X22+237.56X2X3,在10月10日播种,216万苗/hm2基本苗,追肥量225 kg/hm2时,预测产量将达最大值,为12 161.91 kg/hm2。播量和追肥量与周麦23号穗数和穗粒数分别表现为二次曲线和线性关系,而千粒重同时受播期、播量和追肥量的共同作用。周麦23号的沉降值、揉混仪峰宽、8 min带宽均受播期和追肥量互作影响,和面时间受播期、播量与追肥量的共同作用。建议周麦23号在高肥水地块于10月13日播种,基本苗216万~270万苗/hm2,于拔节期追施尿素225~255 kg/hm2,若遇暖冬年份,播种期可适当推迟,增加播量。

摘  要:
In order to offer high yield and high quality cultivation theory for the new wheat cultivar Zhoumai 23,the quadratic regression rotatable orthogonal design with three factors was used to study the effects of different cultivation measures,including seeding date(X1),seeding rate(X2) and nitrogen rate(X3),on main agronomic characters and quality of Zhoumai 23.The mathematical model of yield on three factors was established by software DPS 6.55,Y=10 660.49-520.18X1-233.93X3-166.38X22+237.56X2X3.The maximal value of grain yield forecasted by the regression equation reached 12 161.91 kg/ha.Sedimentation value,mixograph peak width and width at 8 min were affected by interaction between seeding date and nitrogen rate.It was advised that Zhoumai 23 was seeded on October 13,with seeding rate of 2.16-2.70 million seedlings/ha,and addition of nitrogen rate of 225-255 kg/ha at the jointing period.
