摘  要:
[目的]探索浓缩沼液对结球生菜产量及抗病性的影响。[方法]以结球生菜为试材,对结球生菜的根部灌施沼液、肥料和清水;对结球生菜的叶面喷施沼液、肥料和清水,探讨浓缩沼液应用于结球生菜的最佳施肥方式,以及对其产量、抗病性等方面的影响。[结果]施用沼液的结球生菜的产量高于肥料组和清水组,且灌施沼液的结球生菜的产量最高,为24666.0 kg/hm~2,高于清水组38.37%,高于肥料组14.78%;灌施沼液组处理的结球生菜的产量与清水组之间差异性显著,与肥料组之间差异性不显著。灌施沼液组处理的结球生菜的抗软腐病高于清水组24.94%,两者之间差异性显著。[结论]浓缩沼液有利于提高结球生菜产量与质量。

摘  要:
[Objective]The aim was to study effect of concentrated biogas slurry on yield and disease resistance of head lettuce.[Method]Taking head lettuce as test materials,the effect of concentrated biogas slurry on yield and resistance of lettuce that was irrigated,sprayed concentrated biogas slurry,fertilizers and water were studied.[Result]The results showed that compared with water,biogas slurry increased yield by 38.37%(24 666.0 kg/hm~2),and the yield difference of the two treatments was significant.Comparing with fertilizer,biogas slurry increased yield by 14.78%,and the yield difference of the two treatments was no significant.Comparing with water,biogas slurry increased disease resistance by 24.94%,and the disease resistance difference of the two treatments was significant.[Conclusion]Concentrated biogas slurry could improve yield and quality of head lettuce.
