摘要
采用大区（4个试验点）对比法,设置了2种施肥方案,研究了腐植酸生物有机无机生态肥对玉米生育性状及产量的影响。试验结果表明,4个试验点施用腐植酸生物有机无机生态肥较未施用此肥的处理,均改善了玉米的生育性状,促进了玉米植株健壮生长,株高增高4.4~7.0 cm,玉米穗粒数增加32.3~72.2粒,百粒重提高0.9~1.9 g,玉米亩产量增加54.4~95.2 kg,增产率为11.6%~17.2%。
The effects of humic acid bio-organic and inorganic ecological fertilizer on maize growth characters and yield were studied by regional （four sites） correlation method and two fertilization schemes. The results showed that applying humic acid bio-organic and inorganic ecological fertilizer in the four sites compared with control groups （non-used this fertilizer）, maize growth characters were improved, plant growth was stronger, plant height was increased by 4.4- 7.0 cm, ear of grains number was increased by 32.3 - 72.2, the hundred-grain weight was increased by 0.9 - 1.9 g, per-acre yield was increased by 54.4- 95.2 kg, the increasing rate was 11.6% - 17.2%.
