摘要
以夏玉米为研究对象,设置不同的生物黄腐酸肥料施用量及常规化肥减量处理,研究生物黄腐酸肥料及在化肥减量的基础上对玉米性状、产量、效益的影响。试验结果表明,与常规施肥相比较,夏玉米亩增施10 kg生物黄腐酸肥料,亩增产51.3 kg、增幅8.2%;亩增施20 kg生物黄腐酸肥料,亩增产69.4 kg、增幅11.1%。常规化肥减量20%的条件下,亩增施10 kg生物黄腐酸肥料,夏玉米亩增产26.9 kg、增幅4.3%;在化肥减量30%的条件下,亩增施10 kg生物黄腐酸肥料,夏玉米亩增产18.1 kg、增幅2.9%。施用生物黄腐酸肥料可显著提高夏玉米的行粒数、穗粒数,进而提高其亩产量,在常规化肥减量20%~30%的情况下,可实现玉米的增产、稳产。
In order to research the effect of summer corn character,production and benefit on used the biology fulvic acid fertilizers and reducing fertilizer,the different biology fulvic acid fertilizer application amount and conventional fertilizer reduction treatment were set in this paper.The results showed that compared with conventional fertilization,adding biological fulvic acid fertilizer 10 kg/667 m2 and 30 kg/667 m2 could increase summer corn yield by 51.3 kg/667 m2（8.2%）and 69.4 kg/667 m2（11.1%）,respectively.In the case of reducing 20%and 30%amount conventional fertilizer,adding biological fulvic acid fertilizer 10 kg/667 m2 increased the yield by 26.9 kg/667 m2（4.3%）and 18.1 kg/667 m2（2.9%）respectively.Thus,biological fulvic acid fertilizer could increase kernel numbers per row,grain number per spike and yield of summer corn,so much as keep summer corn increased or stable yield under the condition of reducing 20% and 30% amount conventional fertilizer.
