红薯叶面喷施氨基酸水溶肥料效果研究

摘要

The study results of the effect of amino acid water-soluble fertilizer on sweet potato by leaf surface spraying showed that ,after spraying the amino acid water-soluble fertilizer ,the biological characters of sweet potato were improved ,the length of main stem ,stem diameter of main vine ,leaf number and yield per plant increased,the average yield increased 3 350 kg/hm2,growth rate was 5.58%,and the difference was extremely significant.%红薯叶面喷施氨基酸水溶肥料的肥效研究结果表明，喷施氨基酸水溶肥料改善了红薯的生物学性状，增加了红薯的主蔓长度、主蔓茎粗、单株叶片数和单株产量，平均增产3350 kg/hm2，增产率为5.58%，产量差异达极显著水平。
