【摘要】 为了探索适宜陕西关中气候特点的立体草莓栽培苗期水肥供给最佳浓度组合,以"A"字型3层槽装填无土栽培基质（草炭∶蛭石∶无机盐=1∶2∶1）为栽培体系,以2个基质含水量（W₁、W₂）,3个水溶肥浓度（F₁、F₂、F₃）组成的W₁F₁、W₁F₂、W₁F₃、W₂F₁、W₂F₂、W₂F₃及CK （清水,基质水分含量100%）处理,研究在草莓立体栽培槽架中,不同梯度处理水肥供给对植株生长、干物质积累及水分利用率的影响。研究结果表明,W₁F₂（基质含水量30%,水溶肥浓度0.1%）在保障植株正常营养生长情况下,未造成植株徒长,地下部分干物质积累较多,根冠比大于高水肥灌溉模式。更多还原

【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.更多还原
