调亏灌溉下沼液配比对番茄生长、产量和品质的影响
Effects of Biogas Slurry Ratio under Regulated Deficit Irrigation on Tomato Growth,Yield,and Quality
摘要
Abstract
To investigate the effects of biogas slurry ratio under deficit irrigation on tomato growth,yield and quality,this study conducted a greenhouse tomato planting experiment from October 2024 to April 2025.Conventional drip irrigation practices employed by farmers served as the control(CK),while nine deficit irrigation and biogas slurry ratio treatments(T1—T9)were established under indirect subsurface drip irrigation.At different growth stages,tomato of each treatment was applied with different proportions of biogas slurry,specifically,T1(1∶4 for the growth period),T2(1∶4 for seedling stage,1∶6 for flowering and fruiting stage,1∶8 for fruit maturing,the same below),T3(1∶4,1∶8,1∶6),T4(1∶6 for the whole growth period),T5(1∶6,1∶4,1∶8),T6(1∶6,1∶8,1∶4),T7(1∶8 for the whole growth period),T8(1∶8,1∶4,1∶6),T9(1∶8,1∶6,1∶4).The physiological,ecological,yield,and quality indicators of tomatoes under different treatments were measured to explore their response patterns,and the TOPSIS method was employed to evaluate and analyze the comprehensive benefits of tomato cultivation.The results indicated that at the end of the growth period,T7 treatment exhibited the highest plant height and stem diameter,measuring 1.83 m and 18.70 mm,respectively;T1 treatment showed the lowest plant height,while T9 treatment exhibited the lowest stem diameter.The T3 treatment achieved the largest leaf area,and T4 treatment demonstrated the most favorable leaf chlorophyll content.Across the seedling stage,flowering-fruiting stage,and ripening stage,T4,T6,and T1 treatments showed the highest total dry matter accumulation,respectively.T4 treatment yielded the highest tomato production(4.15 kg/plant),followed by T5 treatment(3.61 kg/plant).T2 and T5 treatments achieved the highest soluble sugar content,while T6 treatment exhibited the highest titratable acidity and lycopene contents.The T4 treatment had the highest soluble solids,vitamin C,and soluble protein contents.The comprehensive benefit evaluation results showed that T4 was the optimal treatment in the experiment.关键词
