氨基酸复合叶面肥在小麦生长中的作用

[目的]探讨氨基酸复合叶面肥在小麦生长中的作用，以探求高质量的叶面肥及施用方法。[方法]于小麦拔节、孕穗、齐穗、灌浆4个生长期喷施氨基酸复合叶面肥，对其产量进行比较。[结果]啧施1次、2次、3次、4次比CK组均有提高。尤其啧施4次比CK组在成穗率、千粒重、穗重、穗粒、其产量分别提高6．12％、3．43％、9．66％、6．95％和16．39％。喷施1次、2次、3次、4次比CK有逐次递增的情况，即0〈1〈2〈3〈4，而且较显著。[结论]微量元素对提高植物新陈代谢具有非常重要的作用。

The Function of the Compound Foliar of Amino Acid in Wheat Growth

[Objective] The role of the compound foliar of amino acid in wheat growth was investigated in order to find good-quality foliar application and its application method.[Method] The compound foliar was sprayed in four growth stages: wheat jointing,booting,full heading and grouting and yields at the different treatments were compared.[Results] The yield from the treatment in once,twice,three times and four times' spraying was higher than that of the CK;in particular,the rate of panicle formation,1 000 seed-wei...
