摘要:: 以叶用枸杞“宁杞9号”为试材，采用田间对比试验，以常规沟灌施肥为对照(T1)，研究水肥一体化技术(T2)对叶用枸杞“宁杞9号”含水量、干物质积累及养分吸收规律的影响,以期为叶用枸杞节肥灌溉技术提供参考依据。结果表明：1）水肥一体化技术灌溉模式土壤含水量明显高于常规灌溉模式，且可以满足叶用枸杞所有根系对水分的需求，减少土壤水分的无效损失。2）水肥一体化技术显著促进了叶用枸杞干物质的积累，茎和叶干物质积累分别提高42.9%和73.4%。3）T2处理比T1处理N、P2O5、K2O总吸收量分别提高15.8%、27.4%和12.4%。在采摘期T2处理叶中N所占比例较T1处理高29.2％，T2处理P2O5高于T1处理40.2%；在采摘期T2处理K2O高于T1处理32.3%。4）T2处理氮、磷、钾肥料利用率较T1处理提高72%、57%、39%。产量和水分利用率分别提高69%、141%。水肥一体化技术能提高叶用枸杞土壤含水量、干物质和养分积累量，实现了真正意义的节水节肥。

Abstract:: Taking Lycium barbarum leaves ‘Ningqi 9’ as test material,conventional irrigation mode was control (T1),a field experiment was carried out to study the effects of water and fertilizer integration （T2） treatment on moisture content,dry matter accumulation and nutrient absorption of Lycium barbarum leaves,in order to provide reference for fertilizer-saving irrigation technology of Lycium barbarum leaves.The results showed that,1)the soil moisture content of the irrigation mode of water and fertilizer integration technology was significantly higher than that of the conventional irrigation mode,and it could meet the water demand of all roots of Lycium barbarum leaves,and reduce the ineffective loss of soil water.2)The integrated application of water and fertilizer significantly promoted the dry matter accumulation of Lycium barbarum leaves,and the dry matter accumulation of stem and leaf increased by 42.9% and 73.4%,respectively.3)The total absorption of N,P2O5 and K2O in T2 treatment was 15.8%,27.4% and 12.4% higher than that in T1 treatment,respectively.In the picking period，the proportion of N in the leaves of T2 treatment was 29.2% higher than that of T1 treatment，P2O5 in T2 treatment was 40.2% higher than that of T1 treatment,and K2O in T2 treatment was 32.3% higher than T1 treatment.4)The nitrogen,phosphorus and potassium fertilizer use efficiency of T2 treatment was 72%,57% and 39% higher than that of T1 treatment.The yield and water use efficiency increased by 69% and 141%,respectively.Water and fertilizer integration technology could improve the soil water content，dry matter and nutrient accumulation of Lycium barbarum leaves,and realize the real meaning of water and fertilizer saving.
