摘　　要：腐殖酸是高分子有机化合物,溶解于碱和有机溶剂,难溶于水,通常可以提高土壤有机质含量,进而增强水稻抗性和营养物质的吸收。将腐殖酸分别与镁、钾有机结合成为两种新型的肥料。针对两种肥料对水稻产量和抗性的作用进行研究,结果表明腐殖酸镁、钾都能够提高糙米率和降低垩白率,较对照增产1.5%、6.1%,降低垩白率5.3%、7.1%。As a high-molecular compound, soluble in alkaline and organic solution, but insoluble in water, Humic acid can increase the content of organic matter, thus strengthening tolerance to stress and accelerating the absorption of nutrients, The new type fertilizers, Humic acid Magnesium and Humic acid Potassium, are made from Humic acid and Magnesium and Potassium. The application of Humic acid Magnesium and Humic acid Potassium to rice were able to increase brown rice rate by 1.5% and 6.1%, and lower chalkiness rate by 5.3% and 7.1%.
