| 本试验旨在研究菌剂、沼液及其复配对玉米经济性状和产量的影响。用固氮芽孢杆菌W6、巴西固氮螺菌Yu62及固氮巨大芽孢杆菌C4这3种固氮菌分别接种,并与沼液复配后接种玉米,以及这3种固氮菌与解磷假单胞菌S20组成的的4种微生物复合菌剂单独或与沼液复配后接种玉米。结果表明:除百粒重外,单菌剂处理组、沼液处理组及二者复配处理组均较清水组在玉米经济性状及单产方面表现优良。各单菌剂处理组中,固氮巨大芽孢杆菌C4效果较佳,相对于清水处理组,干穗单产增产10.47%。沼液与菌剂配合使用处理玉米的效果要优于相应菌剂单独处理组及沼液处理组。其中,以沼液与菌剂固氮巨大芽孢杆菌C4复合使用效果最佳,相对于清水处理组而言,百粒重增加2.17%,干穗单产增产25.15%,籽粒单产增产12.47%,增产效果明显。沼液与菌剂固氮巨大芽孢杆菌C4复合使用可以促进玉米穗的发育及产量的增加。 |

| Abstract: |
| The aim of this research was to study the effect of microbes,biogas slurry and their combination on the economic characters and yield of maize.The nitrogen-fixing bacteria Bacillus megaterium C4,Bacillus sp.W6,Azospirillum brasilense Yu62,the combination of nitrogen-fixing bacteria with Pseudomonas alealigenes S20 and the combination of bacteria with the biogas slurry were applied to maize in the field.Experimental results showed that the treatments of either single bacterium,biogas slurry or their combination gave a more excellent performance than water treatment in terms of maize yield and economic characteristics except kernel weight,Bacteria treatment groups,especially with C4,gave a 10% higher dry ear yield compared to the water treatment group.The combination of biogas slurry with these bacteria was superior to individual use on maize.In particular,the combined biogas slurry with microbial agent C4 had increases of 2.17% kernel weight,25.15% dry ear yield and 12.47% grain yield comparing to the water treatment. |
