氨基酸复合叶面肥在小麦生长中的作用

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

[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]喷施1次、2次、3次、4次比CK组均有提高。尤其喷施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。

[ Objective ] The roleof 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 paniele formation, 1 000 seed-weight, spike weight, number of seed per panicle and yield of wheat in the treatment of four times＇ 4 spraying was 6.12%, 3.43%, 9.66%, 6.95% and 16.39% more then those of the CK. The order of the treatment of spraying time was 0 〈 1 time 〈 2 times 〈 3 times 〈 4 times, which was significant difference in the comparison between two treatments each other. [ Conclusion] The treatment of trace elements played an important role in the improvement of plant metabolism.
