【摘要】 基于非石灰性潮土26年的定位试验,在12个不同处理CK、N1、N2、M1、M1N1、M1N2、M2、M2N1、M2N2、NP2K、N2P和N2K中,于2003年研究了长期定位施肥对非石灰性潮土重金属状况的影响,结果表明,长期施肥和灌溉各处理土壤Fe、Mn、Cu、Zn含量均高于试验前的土壤,富集量分别为10.22%～15.18%,12.66%～67.66%,18.27%～130.54%和70.31%～129.98%。长期单施有机肥及其配施无机化肥的土壤Pb的积累量低于不施肥土壤,施用无机化肥,土壤Pb的积累量比试验前高1.46～6.17倍,施用过磷酸钙和氯化钾肥料,土壤Cd富集量高出试验前340.25%～3861.58%,影响到土壤的环境质量,但对作物籽粒的卫生品质影响不大。更多还原

【Abstract】 This experiment was done in the 26 years fixed position experiment of non-calcareous fluro-aquic soil during the year of 2003,12 treatments were designed: CK,N₁,N₂,M₁,M₁N₁K,M₁N₂,M₂,M₂N₁,M₂N₂,NPK,NP and NK. The effects of long-term located fertilization on status of heavy metals in the non-calcareous fluro-aquic soil were studied. The results indicated that: The content of soil Fe,Mn,Cu,Zn under the treatments of long-term fertilization and irrigation were higher than the soil of before the trial, the accumulation amount is 10.22%～15.18%,12.66%～67.66%,18.27%～130.54% and 70.31%～129.98%.The accumulation of soil Pb in the treatments of only application organic fertilizer and combined application inorganic fertilizer was lower than non-application fertilizer. The accumulation of soil Cd in the treatments of application inorganic fertilizer was 1.46～6.17 times than that of before the trial, and it was 340.25%～3861.58% times under application superphosphate and KCl fertilizer. It can influent the soil environment quality, but little influent the sanitation quality of crop seeding.更多还原
