含腐植酸水溶肥料对玉米苗生长及土壤改良的影响
Effect of Water-soluble Fertilizers Containing Humic-acids on Maize Seedlings Growth and Soil Properties
摘要
Abstract
A pot experiment was conducted to assess the impact of various formulations of water-soluble fertilizers containing humic acids(WSF)on acidified brown soils in Yantai city with non-fertilizer treatment serving as control group(CK).6 topdressing treatments,including Market No.1(HJ),Market No.2(GL),Market No.3(LD),Market No.4(XZ),self-developed No.1(NY)and self-developed No.2(NE),were applied at 2 application rates per fertilizer of 0.4(-0.4)or 2.0 mL·kg1-soil(-2.0).The impacts of different treatments on maize seedling height,stem diameter,biomass,cadmium(Cd)content,as well as soil physicochemical properties and available Cd content were compared.The results indicated that,compared to CK,the application of NY,XZ and NE elevated soil pH by 0.57～0.61,0.55～0.62 and 0.49～0.64 units,respectively.The total exchangeable acidity of the soil treated with NY-0.4,NE-0.4 and XZ-2.0 decreased by 28.0％,23.3％and 12.5％,respectively,accompanied by a corresponding decrease in exchangeable aluminum content by 51.2％,29.1％and 18.0％.These outcomes were indicative of the potential to mitigate soil acidification and alleviate aluminum toxicity.The application of WSF generally augmented soil organic matter content,reduced soil electrical conductivity,improved the availability of soil nutrients,lowered soil cadmium availability,and fostered the growth of maize seedlings while inhibiting Cd absorption.These improvements collectively contributed to enhancing soil quality and crop quality.Soil acidity emerges was a pivotal factor influencing the activation,absorption and accumulation of Cd in the soil-maize seedling system.A comprehensive analysis of maize seedling growth and soil improvement revealed that the XZ product outperformed the other tested formulations.Above results provided valuable insights into the effects of WSF product properties,compositions and dosages on fertilizer efficacy,offering a reference for optimizing maize fertilization strategies and ameliorating degraded soils.关键词
