摘要: 为了探究关中中部地区冬小麦的最佳播期和播量,为冬小麦优质高产栽培技术提供理论依据。2015-2016年在关中中部灌区以‘西农509’为供试材料,采用两因素二次D饱和最优试验设计,在大田条件下进行不同播期和播量对小麦产量和品质的影响试验。结果表明,当‘西农509’目标产量为8250~9750 kg/hm2时,适宜播期10月12日到10月18日,适宜播种量125.3~154.0 kg/hm2,播期与播量互作效应最佳处理的播期为10月12日、播种量为136.8 kg/hm2,产量可达最高9265.5 kg/hm2。不同播期播量对‘西农509’品质有也有较大的影响,早播且适当增加密度有利于提高小麦蛋白质含量、湿面筋含量、沉降值、稳定时间和硬度。

Abstract: The aims are to explore the optimum sowing date and sowing rate of winter wheat in central Guanzhong and provide a theoretical basis for high quality and high yield cultivation techniques of winter wheat. In 2015-2016, in central Guanzhong irrigation area, the wheat variety‘Xinong 509’was used as the material, and the two factors quadratic D saturation optimum experiment design was conducted to study the effects of different sowing dates and sowing rates on yield and quality under field condition. The results showed that, when the target yield of‘Xinong 509’was 8250-9750 kg/hm2, the suitable sowing date was October 12th-18th, and the suitable sowing rate was 125.3 -154.0 kg/hm2. The best treatment of the interaction was that, the sowing date was October 12th and the sowing rate was 136.8 kg/hm2, the yield of‘Xinong509’could increase to 9265.5 kg/hm2. Different sowing dates and sowing rates had great effect on the quality o‘f Xinong509’, early sowing date and proper increase of sowing density were beneficial to improve the protein content, wet gluten content, sedimentation value, stability time and hardness.
