奇善宝拌种对中麦895产量及品质的效应

Effect of Growth Regulator Qishanbao on Yield and Quality of Wheat 895

试验于2013—2014年在西北农林科技大学北校区试验田进行,研究了奇善宝拌种对中麦895小麦产量及品质的效应.结果表明:奇善宝拌种后中麦895产量为5 889.8 kg/hm2,较对照增加178.4 kg/hm2,增幅3.1%,成穗数和穗粒数变化不大,千粒重显著提高.奇善宝拌种可显著提高中麦895籽粒品质,容重提高3.5%、稳定时间提高7.1%,沉降值提高4.7%,蛋白质含量提高3.5%,湿面筋提高4.2%,延展性提高1.3%,吸水率和最大拉伸阻力变化不明显.

The test was conducted in the experimental field in the north campus of northwest agriculture and forestry university in 2013- 2014,and effect of the growth regulator Qishanbao on yield and quality of wheat 895 was studied. The result indicates that the yield of wheat 895 after dressing with the growth regulator Qishanbao was 5 889. 8 kg / hm2,and the yield was increased178. 4kg / hm2 by contrast,and the magnitude of the increase was 3. 1%,number of wheat and grain number per ear of wheat were not changed,but 1 000 grains weight increased significantly. Dressing seeds with the growth regulator Qishanbao can significantly improve the grain quality of wheat 895,and its bulk density,stable time,sedimentation value,protein content,wet gluten,and ductility increased by 3. 5%,7. 1%,4. 7%,3. 5%,4. 2% and 1. 3% respectively,but changes of the water absorption rate and the maximum tensile resistance were not obvious.
