以4年生枸杞宁杞一号为供试材料，采用随机区组试验设计，研究了不同沼液用量(0、6、8、10、12和14 kg·-1)对枸杞生长、品质和产量的影响.结果表明，增施沼液可以加快枸杞的新梢生长，提高叶面积和叶绿素含量，促进多糖、类胡萝卜素、黄酮和甜菜碱的积累，同时增加枸杞果实百粒质量及产量.不同沼液用量对各指标的影响存在显著差异：新梢生长呈先上升后下降趋势，叶质量与叶面积指标在施用10 kg·株-1（基肥和追肥各 5 kg·株-1）沼液时出现峰值，叶绿素含量随沼液施用量的增加明显上升，施用量高于12 kg·株-1（基肥和追肥各6 kg·株-1）时叶绿素含量基本稳定；多糖和甜菜碱含量分别在施用10和12 kg·株-1 时达到最大，类胡萝卜素含量随施用量增加而增加，而黄酮含量增幅不明显；单株干果产量随施用量的增加有所增加，在达到10 kg·株-1 后，产量基本保持稳定.综合来看，在现有施肥基础上配施10 kg·株-1 沼液对枸杞生长、品质及产量有显著促进作用.
By using a four-year old Ningqi NO.1 as the tested material, different amounts of biogas liquid manure (0, 6, 8, 10, 12, 14 kg per plant) were applied to study their effects on the growth, quality and yield with a random block experimental design. The results showed that the application of biogas liquid manure not only increased the aboveground biomass, leaf area index and chlorophyll content， but also enhanced the 100-seed mass, yield, polysaccharide, carotenoid, flavonoid and betaine content in the fruits. There were significant variations in different treatments. Spring shoot growth rates increased first and decreased afterwards. Leaf area and biomass peaked under the treatment of 10 kg per plant. With the increase of the application of biogas liquid manure, chlorophyll content presented an obviously rose and tended to be stable when the application of biogas liquid manure was higher than 12 kg per plant. Polysaccharides and betaine content reached maximum value under 10 and 12 kg per plant respectively. Carotenoid content and dried fruit mass increased while flavonoid content did not increase with application of biogas liquid manure, and the dried fruit mass of aplication of biogas liquid manure 10 kg per plant tended to be stable. The combination of the existing fertilization with the application of biogas liquid manure 10 kg per plant had significant effects on the growth, quality and grain yield.
