试验结果表明 ,小麦拔节期叶面喷施 MFB多功能抗旱剂可使小麦产量提高 6.8%～ 2 2 .9%,平均增产达 1 3 .95%,与对照相比差异显著。喷施 MFB多功能抗旱剂还可改善小麦籽粒营养品质 ,与对照相比 ,小麦粗蛋白含量、面筋含量和赖氨酸含量分别增加 0 .98、3 .77和 0 .0 7个百分点。小麦增产的原因是喷施 MFB多功能抗旱剂可使小麦千粒重、穗数和穗粒数增加 ,并使小麦抗逆性增强 The results showed that spraying MFB multi-functional anti-drought agent on wheat leaves at jointing stage could increase wheat yield by 6.8% -2.29% and increase average yield by 13.95%, which was significantly different from the control. Spraying MFB multifunctional anti-drought agent can also improve the nutritional quality of wheat grains, compared with the control, wheat crude protein content, gluten content and lysine content increased 0.98,3 .77 and 0. .0 7 percentage points. The reason for increasing yield of wheat is that MFB multipurpose drought-resisting agent can increase 1000-grain weight, panicle number and grains per spike, and enhance wheat’s resistance
