为了探讨矿源黄腐酸钾对大豆农艺性状及产量的影响,进而研究黄腐酸钾在大豆种植上的合理应用方法,开展了黄腐酸钾叶面喷施和拌种试验。试验结果表明:黄腐酸钾拌种对大豆农艺性状的影响比初花期喷施大;叶面喷施黄腐酸钾和采用黄腐酸钾拌种均可提高大豆产量,在试验条件下,产量均比对照提高25.3%;黄腐酸钾拌种是大豆种植的最佳应用方法。
In order to study the effect of mineral source fulvic acid potassium on the agronomic characters and yield of soybean, and further to study the rational application of fulvic acid potassium in soybean planting, the foliage spraying and seed dressing experiment of fulvic acid potassium was carried out. The results showed that effect of fulvic acid potassium seed dressing on the agronomic characters of soybean was greater than that of foliage spraying at the initial flowering stage. The yield of soybean could be increased both by spraying fulvic acid potassium on the leaf surface and applying fulvic acid potassium to seed dressing. Under the experimental conditions, the yield of soybean was increased by 25.3% than that of the control. Fulvic acid potassium seed dressing was the best application method for soybean planting.
