摘　　要：腐植酸钾是含腐植酸水溶肥料的关键组分,其品质的优劣直接影响产品施用效果。为提高过程检测效率,改善产品使用效果,本文对12种矿物源腐植酸钾的指标进行分析对比;同时做了不同腐植酸钾制成的含腐植酸水溶肥料对玉米生长的影响初步研究。结果表明,黄腐酸占水溶性腐植酸的比例、酸性条件下水不溶物含量、E4/E6值这3个指标可作为筛选生产含腐植酸水溶肥料原料——腐植酸钾的依据;黄腐酸占水溶性腐植酸比例高的腐植酸钾能够更好地促进玉米植株的生长。The potassium humate is the key component of water-soluble fertilizers containing humic acid,and its quality directly affects the application effect of the product.In order to improve the efficiency of process detection and the use of products,the indicators of twelve mineral sources of potassium humate were analyzed,and the effects of water-soluble fertilizers containing humic acid made from different potassium humate on the growth of maize were studied.The results showed that the proportion of fulvic acid to water-soluble humic acid,water insoluble substance content under acidic conditions and E4/E6 could be used as the basis for selecting potassium humate,which was the raw material of water-soluble fertilizers containing humic acid.The potassium humate with high proportion of fulvic acid to water-soluble humic acid could promote the growth of maize plants.
