Moderate Addition of Filter Mud Promotes Sugar Beet Growth by Improving Soil Phosphorus Composition and Nutrient Levels
摘要
Abstract
Objective Sugar beet is a vital sugar crop.Filter mud,a waste product from the sugar industry,contains organic matter and various mineral elements essential for plant growth,making it suitable for reuse as fertilizer or soil conditioner.Methods In this study,sugar beet was sown after 60 days of cultivation in black soil mixed with filter mud at different ratios.Seven treatments were established:F0,F0.5,F1,F3,F5,F7,and F9(filter mud contents of 0％,0.5％,1％,3％,5％,7％,and 9％,respectively).The effects of filter mud addition on soil improvement and sugar beet growth were analyzed by measuring soil physicochemical properties,phosphorus components,sugar beet biomass,and nutrients.Results indicated that filter mud addition significantly increased soil pH,with the highest and most stable pH observed at 3％and 5％filter mud content.At 3％filter mud content,Mg2+and Ca2+concentrations increased significantly,while Fe2+decreased by approximately 20.48％.Soil aggregate structure significantly improved in the 0.5-1 mm and 0.25-0.5 mm particle size fractions at 3％and 5％filter mud content,effectively enhancing soil structure.Adding 3％and 5％filter mud significantly increased the content of active phosphorus and available phosphorus in the soil phosphorus fraction,while adding 1％filter mud gradually elevated the content of stable phosphorus in the soil.Concurrently,adding 3％and 5％filter mud promoted increases in fresh weight of sugar beet plants by 33.86％and 35.58％,respectively,and dry weight by 86.32％and 89.18％,respectively.The increase in biomass showed a significant positive correlation with the improvement in soil physicochemical properties,indicating that adding filter mud at appropriate levels significantly promotes sugar beet growth.Conclusion Adding 3％-5％filter mud effectively promotes sugar beet growth by improving soil aggregate structure and enhancing the supply of available phosphorus and mineral nutrients.关键词
