Effects of Different Water and Fertilizer Supply Levels on Growth and Water Use Efficiency of Strawberry under Soilless Cultivation in Greenhouse

In order to explore the best concentration combination of water and fertilizer supply for three-dimensional strawberry cultivation in Guanzhong，Shaanxi Province，soilless culture medium（peat∶vermiculite∶inorganic salt=1∶2∶1）was used as culture system，W1F1、W1F2、W1F3、W2F1、W2F2、W2F3 and CK（clear water，100% water content of substrate）were treated with two water contents（W1，W2）and three water-soluble fertilizer concentrations（F1，F2，F3），effects of different gradient treatment on plant growth，dry matter accumulation and water utilization rate were studied in the three-dimensional cultivation of strawberry.Results showed that W1F2（30% water content in the substrate and 0.1% water-soluble fertilizer concentration）did not cause excessive plant growth，accumulated more dry matter in the underground part，and root shoot ratio was higher than that of high water and fertilizer irrigation mode.
