摘要
为给小麦高产优质栽培中微肥施用提供参考,以冬小麦品种石新828为材料,研究了叶面喷施锌、铁、硒3种微肥对小麦产量、籽粒锌、铁、硒和蛋白质含量的影响。结果表明,3种微肥中只有喷硒增产作用显著(P<0.05),但喷锌、铁、硒分别显著增加了千粒重、穗数和穗粒数。3种微肥均能明显提高籽粒中相应的微量元素含量,但对籽粒蛋白质含量影响均不显著。
With the cultivar Shixin 828 as material, a field experiment was conducted to study the effects of three microelements,i, e. zinc （Zn）, iron （Fe） and selenium （Se） on yield components and the contents of Zn, Fe and Se, and crude protein in grains of winter wheat at maturity,for providing reference to microelement fertilization in the wheat high yield and high quality cultivation. The results showed that, the yield of wheat sprayed with the three microelements were all increased, but only the yield increase of the sparying se treatment was significant （P〈0.05）. Three kinds of trace element fertilizers could obviously increase the content of the corresponding contents of trace elements , but have no significant effect on grain protein content.
