摘　　要：通过对等量肥效的控释肥和普通化肥处理的"全明星"草莓生长发育、产量品质以及肥料利用效率的研究发现,控释肥处理草莓的茎粗、株高及叶面积显著高于普通化肥处理;控释肥处理草莓的叶片光合速率、叶绿素含量、根系活力显著高于普通化肥处理,并一直维持较高水平;与对照相比,各肥料处理草莓的品质有所下降,但控释肥处理的下降幅度较小,对品质的影响低于普通化肥处理;在氮磷钾的农学利用效率方面,控释肥处理始终高于普通化肥处理。In order to find appropriate fertilizer for the growth of strawberry in greenhouse,with ＂All-Star＂ strawberry（Fragaria ananassa Duch cv.＂All Star＂）as test material,a greenhouse experiment was conducted to study the effects of controlled release fertilizer on the growth potential,fruit yield and quality and fertilizer use efficiency.The results showed that controlled release fertilizer could significantly enhance the stem thickness,plant height and leaf area of strawberry compared to common fertilizer.The effects of controlled release fertilizer on photosynthetic rate,chlorophyll content,and root vigor of strawberry were significantly higher than those of common fertilizer,and always kept higher level.Compared to no fertilizer treatment,the fertilizer treatments decreased the quality of strawberry,but the influence of controlled release fertilizer on quality of strawberry was smaller than that of the common fertilizer.In the agronomic efficiency of nitrogen,potassium and phosphorus,the controlled release fertilizer was always higher than common fertilizer.
