以玉米为研究对象,通过大田肥效试验,对比研究了史丹利含活化腐植酸第四元素复合肥料与未活化腐植酸肥料在玉米上不同施用效果。结果表明,施用活化腐植酸肥料处理的玉米生物学指标整体上最佳,且其产量构成指标及玉米产量均为最佳,与未活化腐植酸肥料处理相比,穗长增加6.4%,秃尖率降低51.9%,籽粒干重增加15%,百粒重增加6.8%,玉米产量增加1320 kg/hm2,增产率达14.4%。综上,说明史丹利含活化腐植酸第四元素复合肥料促进玉米增产效果更佳。
Taking maize as the research object, the effect of different application of Stanley compound fertilizers containing activated humic acid and unactivated humic acid fertilizers on corn was studied through field fertilizer efficiency test. The results showed that the biological indicators of maize treated with activated humic acid fertilizer were the best overall, and the yield components and maize yield were the best. Compared with the untreated humic acid fertilizer, the spike length increased by 6.4% The rate of decrease was 51.9%, the dry weight of kernel was increased by 15%, the grain weight was increased by 6.8%, the yield of corn was increased by 1320 kg / hm2 and the yield was 14.4%. In summary, it shows that Stanley contains the fourth element of activated humic acid compound fertilizer to promote corn yield better.
