摘　　要：为了解不含腐植酸尿素和添加了不同剂量腐植酸的复合肥对玉米生长及养分吸收的影响,研究设定不同的肥料梯度和肥料配比,以探明腐植酸肥料的增产效果和养分利用率.以玉米为试验材料,设无氮处理、复合肥处理、1‰腐植酸+复合肥处理、2‰腐植酸+复合肥处理、3‰腐植酸+复合肥处理、4‰腐植酸+复合肥处理、5‰腐植酸+复合肥处理、6‰腐植酸+复合肥处理共8个施肥处理.试验结果表明,4‰腐植酸复合肥较无氮处理增产率达90%,百粒质量最高,含淀粉量达59.30%,在处理中最具有优势.从综合情况来看,在夏玉米栽培中,加入4‰腐植酸复合肥更有利于玉米增产增效以及贮藏,能获得更大的生物产量和经济效益.In order to understand the effects of compound fertilizers without humic acid urea and with different doses of humic acid added on corn growth and nutrient absorption,different fertilizer gradients and fertilizer ratios were set to explore the yield-increasing effect and nutrient utilization efficiency of humic acid fertilizers.Taking corn as the test material,there are nitrogen-free treatment,compound fertilizer treatment,1‰humic acid+compound fertilizer treatment,2‰humic acid+compound fertilizer treatment,3‰humic acid+compound fertilizer treatment,4‰humic acid+compound fertilizer treatment,5‰humic acid+compound fertilizer treatment,6‰humic acid+compound fertilizer treatment,a total of eight fertilization treatments.The test results showed that the 4‰humic acid compound fertilizer increased the yield by 90%compared with the nitrogen-free treatment,had the highest 100-grain quality,and had a starch content of 59.30%,making it the most advantageous treatment.From a comprehensive perspective,in summer corn cultivation,adding 4‰humic acid compound fertilizer is more conducive to increasing corn production,efficiency and storage,and obtaining greater biological yield and economic benefits.
