摘　　要：为了探讨高架基质栽培中不同品种草莓在不同生长阶段适宜的山崎配方营养液浓度(EC值),以草莓品种圣诞红、香野为试验材料,以标准山崎配方营养液为基准,在盛花期前、盛花期后分别设置0.125、0.25倍(B1),0.25、0.5倍(B2),0.5、1倍(B3)标准山崎配方营养液,EC值分别设置为0.6、0.7,0.7、0.9,0.9、1.3,分析不同水肥处理对草莓生长发育、光合特性、果实产量和品质的影响,为山西省设施草莓水肥调控提供理论依据。结果表明,总体上,B1处理2个草莓品种株高、冠径、复叶数、叶柄长、SPAD值、胞间CO2浓度最高;B3处理2个草莓品种叶片净光合速率、蒸腾速率最高;不同水肥处理间圣诞红果实品质指标没有显著差异,香野果实品质以B3处理表现最好;2个草莓品种果实单株产量均以B3处理最高。综上,在山西省水质条件下,草莓盛花期前推荐使用0.5倍标准山崎配方营养液(EC值为0.9 mS/cm),盛花期后推荐使用1倍标准山崎配方营养液(EC值为1.3 mS/cm)。To investigate the optimal Yamazaki nutrient solution concentration(EC value)for different strawberry varieties at various growth stages in elevated cultivation,two strawberry cultivars,Ssanta and Kaorino,were used as materials,standard Yamazaki nutrient solution was as the baseline,0.125 and 0.25 times(B1),0.25 and 0.5 times(B2),and 0.5 and 1 times(B3)standard concentration of Yamazaki nutrient solution were set up,with corresponding EC values of 0.6 and 0.7,0.7 and 0.9,and 0.9 and 1.3,respectively,and the effects of different water and fertilizer treatments on strawberry growth,photosynthetic characteristics,fruit yield and quality were analyzed,so as to provide theoretical guidance for strawberry water and fertilizer regulation in Shanxi Province.The results showed that overall,B1 treatment showed the highest plant height,crown diameter,compound leaf number,petiole length,SPAD value and intercellular CO2 concentration for both Ssanta and Kaorino;B3 treatment exhibited the highest leaf net photosynthetic rate and transpiration rate for both Ssanta and Kaorino.There was no significant difference for fruit quality indexes of Ssanta under different treatments,while Kaorino showed the best fruit quality under B3 treatment.Both cultivars achieved the highest fruit yield per plant under B3 treatment.Therefore,under Shanxi’s water conditions,0.5 times standard concentration of Yamazaki nutrient solution(EC value of 0.9 mS/cm)before full flowering and 1 time standard concentration of Yamazaki nutrient solution(EC value of 1.3 mS/cm)after full flowering is recommended.
