摘　　要：评估沼液对桃树增肥增产效果可为农村沼液综合化利用提供科学依据。通过沼液与水的不同比例耦合对桃树的施肥试验,研究沼液的不同施用浓度对桃树光合作用、生长量以及桃树产量和果实品质的影响,试验结果表明,沼液在桃树生产中具有肥效突出、促进生长平衡、增强光合作用能力、果实大、品质好、提高商品率等优点,是一种值得推广的农用有机肥料。Different propotions of biogas slurry and water were applied to peach trees to study the fertility of the slurry with different concentration. The peach tree＇ s photosynthesis, growth, peach yield and fruit quality were determined. The result showed that biogas slurry had significant fertility, which could promote the growth and photosynthesis of peach tree, and ob- tain higher yield and better fruit quality.
