- 摘要:
- 以“丰香”草莓为试材，采用“311-A”最优混合设计，通过盆栽试验方式研究了不同氮磷钾配比施肥对草莓果实维生素C含量的影响。结果表明：氮磷钾不同配比施肥对草莓维生素C含量的影响极显著，通过模型分析，得出钾对草莓维生素C含量的影响最大，氮次之，磷最小，在该试验条件下氮磷钾的最佳用量分别为193、87、153.05 mg/L，最佳配比为N∶P2O5∶K2O=1∶0.45∶0.79。
- Abstract:
- The experiment applied the optimal mixed design of ‘311-A’ with the ‘Fengxiang’ strawberry as the experimental material，the effect of different ratio of N，P and K on the vitamin C content formation of strawberry fruit through the way of pot experiment were studied and also the different effect of applying different NPK ratio fertilization were determined.The results showed that different NPK ratio fertilization had a very significant effect on the vitamin C content of strawberry.Through the analysis of the model，potassium was the first one which had great impact on vitamin C content of strawberry，nitrogen was the second one and phosphorus is the third one.The optimum amount of NPK in this experiment were 193,87,153.05 mg/L,and the optimum ratio was N∶P2O5∶K2O=1∶0.45∶0.79.
