中文摘要:

为探究氨基酸螯合锌对小麦产量和品质的效应，以郑麦1860为试验材料，设置花后喷施0.2%、0.4%浓度的硫酸锌、天冬氨酸锌与甘氨酸锌处理，以喷施清水为对照，在开封龙亭和周口郸城两试点研究喷施锌对小麦产量和品质的影响。结果表明，在龙亭和郸城试点，喷施0.2%天冬氨酸锌后小麦的千粒重显著提高，增幅分别为6.17%和6.58%；小麦产量显著增加，增幅分别为5.05%和5.32%；小麦籽粒容重显著提升，增幅分别为2.16%和2.32%。喷施锌显著降低龙亭和郸城试点小麦粉的弱化度，降幅分别为16.06%~26.98%、12.21%~34.27%。喷施天冬氨酸锌显著提高龙亭和郸城试点小麦粉的湿面筋含量，增幅分别为5.72%~10.51%和5.28%~6.53%；显著增大面团最大拉伸阻力，增幅分别为17.27%~20.96%和12.25%~14.13%；显著增加开封龙亭试点小麦粉的沉降值，增幅为19.69%~28.14%。喷施0.2%甘氨酸锌显著提高龙亭和郸城试点小麦粉的湿面筋含量，增幅分别为6.27%和7.40%；显著增大面团恒定变形拉伸阻力，增幅分别为18.37%和8.21%；显著增加周口郸城试点小麦粉的面团形成时间和稳定时间，增幅分别为36.53%和30.78%。综上所述，花后喷施0.2%天冬氨酸锌可提高小麦千粒重、籽粒产量和容重，降低小麦粉的弱化度，增大小麦粉湿面筋含量和面团拉伸阻力。

英文摘要:

To explore the effects of amino acid chelated zinc on the yield and quality of wheat, Zhengmai 1860 was used as the experimental material. The treatments included spraying 0.2% and 0.4% concentrations of zinc sulfate, zinc aspartate, and zinc glycinate after anthesis, with spraying water as the blank control. The effects of zinc spraying on the yield and quality of wheat were studied. The results showed that spraying 0.2% zinc aspartate significantly increased the 1 000-grain weight of wheat at the two experimental sites of Longting, Kaifeng and Dancheng, Zhoukou by 6.17% and 6.58%, respectively; significantly increased the grain yield of wheat at the two sites by 5.05% and 5.32%, respectively; and significantly increased the bulk density of wheat at the two sites by 2.16% and 2.32%, respectively. Spraying zinc significantly reduced the degree of softening of wheat flour at the two sites by 16.06% to 26.98% and 12.21% to 34.27%, respectively. Spraying zinc aspartate significantly increased the wet gluten content of wheat flour at the two sites by 5.72% to 10.51% and 5.28% to 6.53%, respectively; significantly increased the maximum resistance of dough at the two sites by 17.27% to 20.96% and 12.25% to 14.13%, respectively; and significantly increased the sedimentation index of wheat flour at Longting, Kaifeng site by 19.69% to 28.14%. Spraying 0.2% zinc glycinate significantly increased the wet gluten content of wheat flour at the two sites by 6.27% and 7.40%, respectively; significantly increased the resistance at constant deformation of dough at the two sites by 18.37% and 8.21%, respectively; and significantly increased the dough development time and stability time of wheat flour at the Dancheng, Zhoukou site by 36.53% and 30.78%, respectively. In conclusion, spraying 0.2% zinc aspartate after anthesis can increase the 1 000-grain weight, grain yield and test weight of wheat, reduce the degree of softening of wheat flour, and increase the wet gluten content and tensile resistance of dough.
