    Abstract：This study evaluates the impact of varying phosphorus fertilizer levels on the growth，yield，fruit quality of cucumbers，and soil enzyme activity following a wheat cover crop. A pot trial was conducted using cucumber（Cucumis sativus L.）with fi ve phosphorus application levels：P100（conventional application），P75（75% of conventional application），P50（50% of conventional application），P25（25% of conventional application），and P0（no application）. Results demonstrated that compared with no cover crop treatments，the wheat cover crop positively infl uenced stem diameter，total fresh biomass，total dry biomass，yield，sugar-acid ratio，soluble protein，and VC content while reducing nitrate levels and enhancing soil enzyme activity. Notably，in the wheat cover crop treatments，the P50 treatment yielded the highest production of 1.78 kg per plant，with peak values in stem diameter，total fresh biomass，and total dry biomass observed at 20、35 days post-transplanting. Soluble protein content was the highest in P25 treatment，while P50 treatment exhibited a hi gher VC content and sugar-acid ratio along with a lower nitrate level. Additionally，at 20、35 days after transplanting，urease，acid phosphatase，and alkaline phosphatase activities were significantly higher in P50 than P100. By 50 days after transplanting，sucrase activity in P25 and P50，and catalase activity in P0 and P50 were relatively high and signifi cantly exceeded those in P100. Thus，under wheat cover crop conditions，reducing phosphorus ferti lizer to 8.71 g per plant can effectively enhance cucumber growth，yield，fruit quality，and soil e nzyme activity，making it the optimal phosphorus application level for continuous cucumber cropping.

    Abstract：To address low water and fertilizer use effi ciency and soil secondary salinization from excessive irrigation and fertilization in facility vegetable production，we tested pepper variety‘ Xinrui’ using intelligent， precise drip irrigation and fertilization technology based on in-situ soil moisture monitoring. We implemented four treatments：traditional drip irrigation + traditional fertilizer（WhFh），high-frequency drip irrigation + traditional fertilizer（WlFh），traditional drip irrigation + optimized fertilizer（WhFl），and high-frequency drip irrigation + optimized fertilizer（WlFl）．We examined the eff ects of these treatments on yield，growth indices，water and fertilizer use effi ciency，soil mineral nitrogen，and salt accumulation．Results showed that WlFl treatment reduced irrigation and fertilizer application by 29.9% and 50.0%，respectively，compared to WhFh，with no impact on pepper yield．However，leaf area increased by 63.6%，and the dry mass of roots，stems，and leaves rose by 29.5%，29.7%，and 24.0%，respectively．Additionally，N，P2O5，and K?O recovery in WlFl increased by 50.9，27.2，and 46.2 percentage points compared to WhFh．High-frequency drip irrigation reduced water loss by 44.7% to 66.4% and increased water utilization by 14.5-15.9 percentage points compared to traditional drip irrigation．Optimized fertilization treatments reduced soil surface watersoluble salt content by 21.4% to 34.7% and soil mineral nitrogen accumulation by 55.1% to 70.0% compared to traditional fertilization．In summary，high-frequency drip irrigation combined with optimized fertilization signifi cantly reduced water and fertilizer inputs and seepage losses，improved water and fertilizer utilization，and reduced soil mineral nitrogen and water-soluble salt accumulation，contributing to the green and sustainable production of facility vegetables.
