摘　　要：为促进草莓基质栽培高质量发展,在使用2年的基质中配施不同比例的有机肥,以期为基质重复利用和提高草莓品质提供理论基础。结果表明:株高、叶宽和叶长均以T6%处理最高,植株冠径以T3%处理最高;配施有机肥显著提高了叶片SPAD值,SPAD值和净光合速率(Pn)均以T6%处理最高;果实可溶性固形物、可溶性糖含量均以T9%处理最高,可滴定酸含量以CK最高,糖酸比和维生素C含量均以T6%处理最高;667 m2产量以T6%处理最高,且显著高于其他处理。因此,配施有机肥可提高高架栽培草莓基质的重复利用效果,以每立方米基质添加6%的有机肥为宜。In order to promote the high-quality development of strawberry substrate cultivation,different proportions of organic fertilizer were applied to the substrate used for 2 years,in order to provide a theoretical basis for substrate reuse and increase strawberry quality.The results showed that the plant height,leaf width and leaf length were higher in T6%treatment,and the plant crown diameter was higher in T3%treatment.The application of organic fertilizer significantly increased the SPAD value of leaves,and the SPAD value and net photosynthetic rate(Pn)were higher in T6%treatment.The contents of soluble solids and soluble sugar in fruits were increased by T9%treatment,the content of titratable acid was higher by CK treatment,and the ratio of sugar to acid and vitamin C content were higher by T6%treatment.The 667 m2 yield was higher in T6%treatment,which was significantly higher than other treatments.Therefore,the combined application of organic fertilizer can improve the reuse effect of elevated strawberry cultivation substrate,and it is advisable to add 6%organic fertilizer per 1 m3 substrate.
