| 摘 要： | 采用盆栽试验方法,研究了微生物菌剂对盐碱土壤微生物、养分、盐分及玉米苗期生长的影响.结果表明,施用微生物菌剂后,盐碱土壤中钾细菌和枯草芽孢杆菌数量、土壤有机质含量、速效N、P、K含量状况均明显高于无添加菌剂对照处理,其中以菌剂施用量为0.4 g·kg-1土的效果最明显.施用微生物菌剂后,土壤pH、含盐量均有不同程度地降低,菌剂施用量0.4 g·kg-1土的处理在前中期表现出较好的土壤脱盐效果,而菌剂施用量0.8 g·kg-1土的处理在后期脱盐效果较好.添加微生物菌剂促进玉米苗期株高和叶片数增加,有利于玉米地上部分干物质的积累,以菌剂施用量0.4g·kg-1土的效果最明显.差异显著性检验表明,菌剂处理玉米株高、干物质重与无添加菌剂对照相比差异均达显著水平,但不同菌剂量处理间差异不明显.综合判定菌剂施用量0.4 g·kg-1土对盐碱土理化和生物性状改良效果较好.

| Abstract: | The effects of inoculating microorganism agents on the soil microorganism, total salinity and corn growth in seedling state were studied with a pot experiment. The results showed that compared with the treatments without inoculating microorganism agents, the treatments applying inoculating microorganism agents resulted in a significant increase in the amount of soil potassium silicate-degrading bacteria and Bacillus subtilis, soil organic matter content and soil available nutrients including nitrogen, phosp... |
