摘要： 为明确微生物菌肥对藏青2000生长、品质及根际土壤性质的影响，对5组不同处理藏青2000的8个生长指标、9个品质指标和8个土壤理化指标进行了检测分析。结果表明无机化肥+微生物施肥组（LSW4）处理的藏青2000生长发育较为良好，产量能够达到2467.52 kg/hm2，较无机化肥组（LSW2）产量提高39.76%；5组不同施肥处理的藏青2000粗蛋白质、粗淀粉、粗纤维含量差异较小，但LSW4处理的藏青2000钙（Ca）、铁（Fe）、镁（Mg）、锰（Mn）、锌（Zn）和铜（Cu）等矿质元素较其他处理组均有不同程度提高；LSW4处理较其他处理组能够提高植物对土壤氮、磷的吸收利用，但对钾的吸收利用差异较小，微生物与无机化肥配合施用对提高藏青2000实际产量增效显著。

Abstract: In order to determine the effects of microbial fertilizer on the growth, quality and soil physicochemical properties of Zang Qing No.2000, eight growth indicators, nine quality indicators and eight soil physicochemical properties indicators of Highland Barley were analyzed among five different fertilization treatments. The results showed that Highland Barley of LSW4 treatment had a rapid growth, its yield could reach 2467.52 kg/hm2, which was 39.76% higher than the yield of LSW2 treatment. Crude protein, crude starch and crude fiber in Zang Qing No.2000 had no significant difference among five different fertilization treatments. However, the contents of calcium, iron, magnesium, manganese, zinc and copper of the LSW4 treatment were higher than other treatments. The LSW4 treatment could improve the absorption and utilization of soil nitrogen and phosphorus compared to other treatments, but the differences in the absorption and utilization of potassium among five different fertilization treatments were negative. It was concluded that the co-application of microbial fertilizer and inorganic fertilizer has a remarkable effect on the improvement of actual production of Zang Qing No.2000.
