以长效腐植酸尿素为基质 ,采用圆盘造粒生产腐植酸系列专用肥。文中介绍了小麦、油菜、水稻、蔬菜4种专用肥的配方及施用量。田间试验表明 :施用腐植酸系列专用肥与普通复混肥相比 ,小麦平均增产 7.2 % ,油菜平均增产 7.2 % ,水稻平均增产 7.3% ,蔬菜平均增产 9.1% ,且可减少施肥次数 Long-term humic acid urea as a substrate, the use of disc granulation production of humic acid series of special fertilizer. This paper introduced the wheat, rape, rice, vegetables, four kinds of special fertilizer formula and the amount of application. Field experiments showed that the average yield of wheat was 7.2%, that of rapeseed was 7.2%, that of rice was 7.3% and that of vegetables was 9.1%, and the number of fertilizations was reduced
