摘要
为研究强筋小麦在冀东地区对不同播期反应差异,2016~2017年在大田条件下,以强筋小麦津农7号和中麦1062为材料,设置3个处理播期,分别是10月10日(SD1),10月15日(SD2)和10月20日(SD3),以10月5日为对照播期(CK),研究了不同播期对强筋小麦产量和籽粒蛋白质质量分数的影响。结果表明:(1)随着播期的推迟,小麦干物质积累量显著降低;(2)产量最高值出现在10月10日这一播期,早播或晚播均会造成不同程度的减产;(3)籽粒蛋白质质量分数随播期的推迟而提高,播期推迟有利于提高籽粒蛋白质质量分数。
In order to reveal the relationship between sowing postponement and the yield as well as the protein content of the strong gluten wheat in the eastern Hebei province,Jinnong-7 and Zhongmai-1062 were used as materials to conduct the field study in the season 2016~2017.Three treatment sowing dates were set on October 10(SD1),October 15(SD2)and October 20(SD3)with October 5 as the control(CK).The results showed that:(1)With the postponement of sowing date,the dry matter accumulation of wheat decreased significantly;(2)The highest yield appeared on October 10,while it would cause different degrees of yield reduction earlier or later;(3)The protein content increased with the sowing postponement,which meant sowing late might be conducive to improving grain protein content.
