中文摘要: |
为给小麦新品种中麦895的推广提供技术支撑,2013-2015在关中中部灌区,采用二次D饱和最优设计方法研究了播期与播量对中麦895产量及品质的效应。结果表明,播期和播量显著影响中麦895的产量,其高产适宜的播期为10月12日-19日,适宜的播量为170.2 kg·hm-2~206.5 kg·hm-2。不同处理之间成穗数、千粒重和产量差异极显著,穗粒数差异显著。播量为185.5 kg·hm-2时,达到最高产量的适宜播期为10月14日-22日;播期为10月14日时,达到最高产量适宜的播量为130.5 kg·hm-2~207.3 kg·hm-2。播期和播量可显著影响中麦895的蛋白质含量和容重,对加工品质和拉伸品质没有显著影响;适期偏晚播种有利于提高中麦895的成穗数和千粒重以获得高产。 |

To study the effects of sowing date and sowing amount interaction on the yield and quality of a new wheat variety Zhongmai 895,a field experiment with the secondary D saturation optimal design was conducted in Central Guanzhong Irrigation Area during 2013-2015. The results showed that the interaction between sowing date and sowing amount had significant effect on yield. The best sowing date was from october 12th to 19th with the suitable sowing amount of 170.2-206.5 kg·hm-2 for the high yield of Zhongmai 895. There were significant difference for spike number,1 000-grain weight,yield and grain number per spike among different treatments. When the planting amount was 185.5 kg·hm-2,the best sowing date for the highest yield was from october 14th to 22th; when the sowing date was october 14th,the corresponding suitable sowing amount was 130.5 kg·hm-2- 207.3 kg·hm-2. The interaction effect between sowing date and sowing amount had significant effect on protein content and bulk weight of Zhongmai 895. However,there is no significant effect on the processing and grinding quality. Late sowing is beneficial to raising the spike number and 1 000-grain weight of Zhongmai 895,to achieve high yield. |
