本试验在陕西长武选用长旱58小麦品种，研究在不同生长发育期叶面喷施奇善宝对小麦产量及品质的影响．试验结果表明，返青期喷的产量、蛋白质含量、吸水率分别比对照增加4．2％、1％和1．23％，生物产量、形成时间、评价值分别降低24．18％、0．57min和3；拔节期喷的产量、蛋白质含量、吸水率、评价值分别较对照增加5．69％、1．43％、0．87％、1．33，生物产量、形成时间、弱化度分别降低2．8％、0．03min、10F．U；孕穗期喷的产量和蛋白质含量分别较对照增加12．4％和0．6％，生物产量、吸水率、形成时间、评价值分别降低14．59％、0．93％、0．27min、1．33．叶面喷施奇善宝能显著提高小麦产量和籽粒蛋白质含量，降低面团的形成时间．%The effect on the yield and quality growth phases of wheat variety Changhan58 in was studied by spraying Qishanbao at different Changwu, Shaanxi. The results show that the yield, protein content, water absorption increased by 4.2%, 1% and 1.23% respectively by spraying Qishanbao at returning green stage. Biological yield, formation time and evaluation value decreased by 24.8%,0. 57min and 3 respectively. The yield, protein content, water absorption and evaluation value increased by 5.69% , i. 43% , O. 87% and i. 33 respectively by spraying Qishanbao at jointing stage. Biological yield, formation time, degree of softening de- creased by 2.8% , 0.03min and 10 F.U. respectively. The yield and protein content increased by 22.6% and 0. 6% respectively, and the biological yield, water absorption, formation time and evaluation value decreased by 14.59% , 0.93% , 0.27min and 1.33 respectively by spraying Qishanbao at booting stage. Our conclusion is that foliar spray of Qishanbao can significandy promote the yield, protein content and reduce dough formation time.
