Response of Winter Wheat Growth and Yield to Application of Water Soluble Fertilizer under Shallow Drip Irrigation

doi:10.7668/hbnxb.20196286

Abstract

Abstract:

To investigate the effects of drip application of water-soluble fertilizers under shallow buried drip irrigation on the growth and yield of winter wheat,field experiments were conducted from 2022 to 2024.The experiments considered two factors:irrigation water volume and fertilization schemes.Irrigation water volume was set at two levels:high and low.The fertilization schemes included traditional base fertilizer+urea as the control F₀,50% base fertilizer+water-soluble fertilizer F₁,0 base fertilizer+water-soluble fertilizer F₂,100% base fertilizer+water-soluble fertilizer F₃,and 100% base fertilizer+water-soluble fertilizer+organic fertilizer(50% humic acid+40% fulvic acid)F₄,totaling five levels.The results showed:compared to the control treatment,reducing base fertilizer by 50% increased plant height,stem diameter,leaf area index(LAI),SPAD value,and yield by 5.02%,13.81%,12.26%,0.16%,and 8.82%,respectively,while the 0 base fertilizer treatment resulted in reduced wheat yield.Compared to urea application,using water-soluble fertilizers increased wheat plant height,stem diameter,LAI,SPAD value,and yield by 5.48%,18.91%,18.49%,2.65%,and 6.05%,respectively.Adding organic fertilizer to water-soluble fertilizers further increased plant height,stem diameter,LAI,SPAD value,and yield by 2.89%,4.88%,5.69%,3.05%,and 6.74%,respectively.Compared to low irrigation water volume,high irrigation water volume increased wheat stem diameter,LAI,and SPAD value by 5.79%,13.94%,and 8.74%,respectively,and wheat yield by 7.23%.Reducing base fertilizer by 50% resulted in the highest profit for wheat,while maintaining base fertilizer application and replacing urea with water-soluble fertilizers reduced profits due to increased costs.Adding organic fertilizer to water-soluble fertilizers increased wheat profits.In conclusion,the combination of water-soluble fertilizers with shallow buried drip irrigation technology has a positive impact on wheat growth.The fertilization schemes of reducing base fertilizer by 50% and applying water-soluble fertilizers,or replacing urea with water-soluble fertilizers and adding organic fertilizer,provide feasible pathways for high wheat yields.
