Effects of Different Microelements on Yield and Quality of Wheat at Flowering Stage
Abstract：In this experiment, the effects of different microelements at anthesis on wheat grain yield and quality were studied. The results showed that different microelements could increase wheat yield at flowering stage, in terms of yield components, mainly increased the wheat grain, and there was no significant difference between the number of grains per spike and the number of spikelets. Trace elements can significantly increase the total protein content of wheat. There is no difference in the content of albumin and globulin between different treatments, but the glutenin and gliadin have been significantly improved compared with the control. Spraying exogenous substances can significantly improve the wet gluten content of wheat flour, dry gluten content and SDS sedimentation value; compared with the control, spraying exogenous substances can significantly improve the high and low molecular weight glutenin subunits.

花期喷施不同微量元素对小麦产量和品质的影响
小麦（Triticumaestivum Linn.）是禾本目（Poales）禾本科（Poceeae）小麦属（Triticum）草本植物，是世界上种植面积最大的粮食作物，也是我国第二大粮食作物。由于农民对小麦产量的侧重，导致我国优质的专用小麦需要大量的进口。生活水平的提高，使得人民对优质专用小麦的需求量大大增加，但是品质指标不协调、面筋质量差等严重阻碍了优质小麦的生产。要解决我国优质小麦供应不足的问题，除了优质的品种外，环境条件也起到非常重要的作用。N、P、K的供应，微量元素和氨基酸液肥的补充，化学调控可以有效的提高或者降低小麦的面筋含量。根据需求的不同，配置不同的外源调控物质。
