摘要
为了研究西农529小麦新品种最适播期与播量,设置10月5日、10月12日、10月17日、10月22日4个播种时期,180×10~4株/hm~2、258×10~4株/hm~2、306×10~4株/hm~2、360×10~4株/hm~2 4个密度处理,采用两因素二次D饱和最优试验设计方式,研究不同播期与密度对其生长发育和产量的影响。结果表明:在关中东部灌区当前的生产水平下西农529最佳播期10月15-22日,最佳播量基本苗257.4×10~4~322.2×10~4株/hm~2时产量最高,可达8 250~9 000 kg/hm~2。
In order to study the optimum sowing date and amount of new wheat variety Xinong 529,Four sowing periods of October 5, October 12, October 17 and October 22 were set, four density treatments of 180 ×10~4 plants/hm~2, 258×10~4 plants/hm~2, 306×10~4 plants/hm~2 and 360×10~4 plants/hm~2 were set up, optimum experiment design of two factors quadratic saturation D was used, the effects of different sowing dates and densities on the growth and yield of wheat variety Xinong 529 were studied. The results showed that under the current production level in the irrigation area of the east Guanzhong, the best sowing period for Xinong 529 is October 15-October 22, and the yield is the highest when the optimal sowing rate is 257.4×10~4 plants/hm~2-322.2×10~4 plants/hm~2, and yield is up to 8 250-9 000 kg/hm~2.
