摘要 ;[目的]为了研究水肥一体化施肥模式对草莓产量水平的影响。[方法]对大棚草莓常规施肥和水肥一体化不同施肥模式进行了比较试验。[结果]水肥一体化施肥模式中菌肥﹢20N ∶10P 2O 5∶20K 2O 10 d一次施肥，产量比常规施肥有0.01水平显著地增加; 与其他水肥一体化施肥模式相比，产量也有显著增加。但是，从前后期产量的差异显著性分析来看，菌肥﹢20N ∶10P 2O 5∶20K 2O 10 d一次施肥处理与常规施肥以及其他不同施肥模式处理之间前期产量差异都不显著，而后期产量存在明显差异。不同施肥方式对草莓的开花结实率的影响不大， 畸形果的发生以201020配方施肥最小，并且畸形果的发生与常规施肥存在0.01水平显著性差异。[结论]大棚草莓水肥一体化施肥方式以菌肥﹢20N ∶10P 2O 5∶20K 2O 10 d一次施肥增产效果最好，而且产量增加主要是通过后期产量的提高来实现的; 同时，菌肥﹢
20N ∶10P 2O 5∶20K 2O 10 d一次施肥可以减少畸形果率的发生。

Abstract ;[Objective]The research aimed to study the effects of Integrated management of water and fertilizer on yield level of Strawberry. [Method] Comparison test had been carried out between conventional fertilization and integrated management of different fertilization mode of water and
fertilizer in greenhouse strawberry. [Result] In the integrated management of water and fertilizer mode "bacteria fertilizer + '20N∶10P 2O 5∶20K 2O'" 10 d once fertilization， the yield of strawberry was significantly increased compared with that of the conventional fertilization. Compared with other integrated management of water and fertilizer model， the yield of strawberry was also increased remarkably. But significant difference analysis between the production of early stage and later stage showed that the difference of the production of early stage between different fertilization modes weren’t significant， but the difference of the production of later stage was significant. Different fertilization treatments had little effects on the rate of strawberry blossom and bear fruit. The occurrence of malformed fruit was minimum in 201020 of fertilization formula. And there were significant differences in the occurrence of malformed fruit between '201020' of fertilization and conventional fertilization.[Conclusion] Among integrated management of water and fertilizer on
