摘  要：
以草莓品种"丰香"为试材,研究了温室栽培条件下,0、40、80、120mg/kg不同土壤氮素水平对草莓果实发育阶段叶片的光合色素、最大光合速率、硝酸还原酶活性和可溶性蛋白质含量的影响,以期为设施草莓土壤氮素管理提供参考依据。结果表明:在花期和坐果期,草莓叶片叶绿素含量、最大光合速率、硝酸还原酶活性和可溶性蛋白质含量随氮素水平的增加而增加,以120mg/kg氮素处理促进作用最强;在果实膨大期、果实转色期和成熟期,草莓叶片叶绿素含量、最大光合速率、硝酸还原酶活性和可溶性蛋白质含量随氮素水平增加呈先增加后减小趋势,以80mg/kg氮素处理促进作用最强。

摘  要：
Taking ‘Toyonoka'strawberry as material,the effect of different nitrogen concentration with 0,40,80, 120mg/kg on photosynthetic pigments,maximum photosynthetic rate,nitrate reductase activity and soluble protein content of post-anthesis strawberry leaves were studied in greenhouse.The results showed that,chlorophyll content, maximum photosynthetic rate,nitrate reductase activity and soluble protein content of strawberry leaves during flowering period and fruit setting period increased with the rising nitrogen concentration,the nitrogen concentration at 120mg/kg had the biggest promotion.While chlorophyll content,maximum photosynthetic rate,nitrate reductase activity and soluble protein content of strawberry leaves during fruit expending period,fruit coloring period and fruit ripening period first increased and then decreased with the increasing nitrogen concentration,the nitrogen concentration at 80mg/kg had the biggest promotion.
