氨基酸微量元素螯合肥对玉米产量和品质的影响

Effects of Amino Acid and Trace Elements Chelated Fertilizer on Maize Yield and Quality

[目的]探讨3种氨基酸微肥(Ⅰ、Ⅱ和Ⅲ)对糯玉米的作用。[方法]在大田条件下,以清水为对照,喷施不同氨基酸微肥,研究对玉米性状、产量、品质的影响。[结果]与清水处理相比,氨基酸微肥明显提高玉米产量,比对照高13.43%以上,其中氨基酸微肥(Ⅲ)产量最高,为31 900.45 kg/hm2,高于对照23.04%,其次为氨基酸微肥Ⅰ29 411.76 kg/hm2和氨基酸微肥Ⅱ29 502.26 kg/hm2,最低是对照25927.60 kg/hm2。氨基酸微肥处理的可溶性还总糖和蛋白质含量显著高于对照,其中氨基酸微肥Ⅲ处理的玉米品质最佳,显著高于氨基酸微肥Ⅰ和Ⅱ处理。[结论]氨基酸微肥Ⅲ对玉米生长影响最大,不仅提高产量,而且改善玉米品质,是一种理想的叶面肥。

[ Objective] The research aimed to study the effects of three kinds of amino acid micronutrient fertilizer （ Ⅰ , Ⅱ and Ⅲ） on waxy maize. [ Method] With pure water as a contrast, the effects of different amino acid micronutrient fertilizer on corn traits, yield and quality were analyzed under field condition. [ Result ] Compared with the water processing, the amino acid micronutrient fertilizer obviously increased the corn yield, more than 13.43% higher than the pure water processing. The yield of amino acid micronutrient fertilizer （ Ⅲ ） was the highest, and 31 900. 45 kg/hm^2, and 23.04% higher than that of contrast, then the yield of amino acid micronutrient fertilizer Ⅰ （29 411.76 kg/hm^2 ） and the yield of amino acid micronutrient fertilizer Ⅱ （ 29 502.26 kg/hm^2 ）. The comparison of 25 927.60 kg/hm^2 was minimum. With amino acid micronutrient fertilizer processing ,the soluble total sugar and protein of corn was significantly higher than the contrast, and the effect of amino acid micronutrient fertilizer （ Ⅲ ） treatment on corn＇ s quality was the best, and significantly higher than that of amino acid micronutrient fertilizer Ⅰ and Ⅱ. [ Conclusion ] Amino acids micrenutrient fertilizer （ Ⅱ ） mostly influenced the maize growth. It not only in- creased the production, but also improved the quality of maize. So it was an ideal foliar fertilizer.
