中文摘要：

以控释肥为试材，进行了草莓保护地栽培的应用研究，并与普通化肥进行了肥效对比。结果表明：控释复合肥能提高草莓鲜果Vc含量和口感，但总糖和总酸度差异不显著；在相同施肥量下控释肥处理比普通化肥处理草莓鲜果和生物产量都显著增加，平均增产均达10％以上，以控释肥处理CRF2（N30、P2O510、K2O20）增产最为明显；控释肥能提高草莓植株中氮磷钾特别是氮磷含量。控释肥养分释放速率具有先低后高再低的趋势，与草莓生长的需肥规律更为吻合，可提高肥效。

英文摘要：

Compared with common chemical fertilizers, effects of controlled-release fertilizers applied on strawberry in greenhouse were studied. Reductive Vc content and taste of strawberry was increased by application of controlled-release compound fertilizer as compared with common fertilizer treatments, but the total sugar and total acid were no significant difference. The fresh fruit yield and total biologic output with controlled-release fertilizer treatments were higher over 10% than the common fertilizers and control treatments,and the yield of CRF2 treatment was the highest. The N,P,K contents of strawberry plant especially the contents of N and P were increased with controlled-release compound fertilizer treatments. The available nutrients in soil with controlled release fertilizers changed from low to high and then to low. The nutrient release characteristic could satisfy the nutrient need by strawberry in every growing stage, which indicated that the controlled release fertilizer applied on strawberry was better than common fertilizer.
