熔体造粒腐植酸功能性专用肥是采用预处理过的风化煤和普通无机复合肥为生产原料,经高温熔融、特制喷头造粒、筛分、计量、包装制成。在大田条件下,研究了熔体造粒腐植酸功能性专用肥对玉米产量及氮肥利用率的影响,试验结果表明,熔体造粒腐植酸功能性专用肥能显著提高玉米产量,在相同施肥量(N、P、K相同)的情况下,与普通肥处理相比,熔体造粒腐植酸功能性专用肥处理增产11.74%,其氮肥利用率显著高于普通肥处理。
Melt granulation humic acid functional specialty fertilizer is the use of pre-treated weathered coal and common inorganic fertilizer as raw materials for production, high temperature melting, special nozzle granulation, screening, measurement, packaging made. Under the field conditions, the effects of melt-granulated humic acid functional specialty fertilizer on corn yield and nitrogen use efficiency were studied. The results showed that the functional granulated humic acid fertilizer could significantly increase the yield of maize, (N, P, K the same), compared with the normal fertilizer treatment, melted granulated humic acid functional specialty fertilizer yield 11.74%, the nitrogen use efficiency was significantly higher than the normal fertilizer treatment.
