水肥耦合对设施草莓生长、产量品质及水分利用效率的影响

EFFECTS OF WATER AND FERTILIZER COUPLING ON GROWTH,YIELD AND QUALITY AND WATER USE EFFICIENCY OF STRAWBERRY IN GREENHOUSE

以"全明星"草莓(Fragaria ananassa Duch cv."All star")为试材,系统探讨了不同水肥组合对草莓生长、产量品质和水分利用效率的影响,旨在寻找适合温室草莓生长的水肥组合,为设施果树栽培提高水肥的利用效率提供理论依据。结果表明:T10和T11处理的植株的生长势较强,其次是T6和T7处理;T6和T7处理在草莓的生长期光合速率较高;不同处理的土壤水势在草莓不同生育期均呈现先升高后降低的变化趋势;T6和T7处理的草莓综合内在品质较好;T6和T7处理具有较高的产量和水分利用效率。综上所述,中等浇水量和高施肥量的T6和T7处理是比较理想的水肥组合。

In order to find appropriate water and fertilizer coupling for the growth of strawberry in greenhouse,with ＂All-Star＂ strawberry（Fragaria ananassa Duch cv.＂All star＂）,a greenhouse experiment was conducted to study the effects of different water and controlled-release fertilizer on the growth potential,fruit yield and quality and water use efficiency.This study will provide theoretical basis and technical support for improving use efficiency of water and fertilizer in horticultural facilities culture.The results showed that T10 and T11 treatments could enhance growth potential of strawberry plants,followed by T6 and T7 treatments;the plant photosynthetic rate of T6 and T7 treatments were the highest in strawberry growth periods;The comprehensive qualities of strawberry in T6 and T7 treatments were better;Yield and water use efficiency of strawberry in T6 and T7 treatments were higher.In summary,T6 and T7 treatments were the optimal combinations of water and fertilizer for strawberry growth.
