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