长期定位施肥对潮土土壤黏土矿物影响的研究
Effect of Long Term Fertilization on Soil Clay Minerals in Soil
摘要
Abstract
Using the 39 years long term fertilization experiment,the soil in the year of 1978,1984,1990,1996,2002,2008 and 2014 were studied.The effect of different fertilization on the soil clay mineral in the soil was studied by X ray diffraction.The changes of relative contents of clay minerals in different fertilization treatments were analyzed,and the results showed that the relative contents of clay minerals could be changed by long-term fertilization.Relative content of the interannual variability of the montmorillonite was higher than that of CK,assumes the trend of escalation,the results most significant (R2=0.991 80),followed by M2 (R2=0.952 86),with the time delay,kaolinite and the relative content of M2N1 decreased most significantly (R2=0.993 10),then M2N2(R2=0.938 89),results M1N2(R2=0.900 00),and kaolinite content of all treatments were lower than CK.Soil relative content of chlorite,organic fertilizer and nitrogen fertilizer treatment compared with CK decreased,according to 2014 showed that,M2N2 decreased the most obvious and 5 percentage points.Single application of N fertilizer treatment hydromica relative content was declined with the passage of time,and N2 (R2=0.948 03) less than N1 (R2=0.883 27),single application of organic fertilizer and organic fertilizer application of nitrogen fertilizer in mica relative content increased year by year,M2N2 highest (R2=0.971 26) followed by the results (R2=0.903 18),M2N1 (R2=0.890 89) that organic fertilizer was conducive to the formation of mica.Long-term single application of nitrogen fertilizer caused by lack of potassium,hydromica mineral layer of non exchangeable potassium continue to release,montmorillonite hydromica the formation of mixed layer relative content also with the passage of time showed a rising trend.关键词
