生物菌肥在玉米栽培上的效果

目的]分析生物菌肥对玉米植株生长、品质、产量的影响。方法]以普通玉米和甜玉米为试验材料，研究自然生长状态下ZH-BBM生物菌肥对玉米的影响。结果]生物菌肥使得普通玉米、甜玉米的穗长、穗粗、单穗重分别提高了29．1％、14．7％、52．3％、10．6％、8．5％、11．5％。而玉米籽粒含水量和秃尖长明显降低，使得普通玉米和甜玉米的产量分别提高了18．2％和11．6％。结论]生物菌肥可明显促进玉米的生长，提高养分的累积量，从而提高产量，改善品质。该研究可为ZH—BBM生物菌肥在玉米上的应用提供科学依据。

Effects of Biological Bacterium Manure in Maize Cultivation

Objective ] The research aimed to analyze the effect of biological bacterium manure on the growth, yield and quality of maize. Method] The influence of using ZH-BBM, a biological bacterium manure, was studied on two maize varieties in natural growth phase. Result] Under using biological bacterium manure, the ear length, ear diameter, ear weight of common maize were increased 29. 1%, 14.7%, 52.3% respectively than the control treatment, while the ones of sweet maize were enhanced 10.6%, 8.5%, 11.5%. The terms of yield of common and sweet maize were added 18.2% and 11.6% than the control. Conclusion] Biological bacterium manure could significantly enhance the growth and accumulation of nutrients for common and sweet maize, so as to improve the yield and quality of sweet maize. The study can provide scientif- ic basis for applying ZH-BBM biological bacterium manure to maize.
