In order to observe the dynamics of soil pH,study the influence of different rates of lime on acidic soil effective nutrient content,analyze the correlation between soil pH and available nutrient contents,a pot experiment was carried out with six kinds of lime dosage,including 0,03,0.9,1.8,2.4,4.8 g/kg.The results showed that lime application significantly improved soil pH.At 90 d,the pH values with the lime dosage of 4.8,2.4,1.8 g/kg increased 2.88,1.16,and 0.74 pH unit,respectively,compared to control.Liming had little effect on soil total nitrogen content,but which had significant effects on soil inorganic nitrogen.In the treatment of application 0~2.4 g/kg range of lime,soil NO-3N content increased with the rates of lime increased by 12.4%~146.8%.But in the treatments in which lime was applied at more than 2.4 g/kg,the soil NO-3N content was decreased significantly.While the opposite change tendency showed for soil NH+4N content,which reduced with the increase of lime.Soil available phosphorus content increased and then decreased with the increase of lime application.For soil available potassium,when the rates of lime>0.9 g/kg,its content significantly reduced with the increase of lime,which fell by 2.9%~21.7%.Liming significantly improved the soil content of Ca,which content increased significantly with the lime increased by 32.3%~543.0%.Whats more,lime application significantly reduced the soil effective Fe,Mn,Cu,and Zn.Besides,when the dosage of lime ≥ 2.4 g/kg,the content of soil available Mn and Zn were in extremely lack conditions.A significant linear negative correlation was found between soil pH values and the contents of soil total nitrogen,NH+4N,available potassium,iron,manganese,copper and zinc.A high significant linear positive correlation was shown between soil pH values and available calcium.A quadratic function could be used to describe the relationships between soil pH and the contents of soil NO-3N,available phosphorus and magnesium,all correlation coefficients were statistically highly significant.There is a good correlation relationship between the soil nutrient and soil acidity,when applying lime on improving soil acidity,the rates of lime should be paid special attention,and soil effective Mn,Zn and other trace elements should be added in a timely manner.
