摘要:Abstract: In order to study evolution characteristics of the anion in vegetable field soil of greenhouse, the soil samples of different cultivating years (0 a, 5 a, 10 a, 15 a, 20 a, 25 a, 30 a) were collected, and their anion contents were determined by using ion chromatograph. The results showed that the contents of Cl−,HJCO3, NO3 , NO2 and SO2-4 were most significantly correlated with the cultivating years. Annual growth of Cl− content was about 25.72 mg•kg−1 during 15 - 30 a, which was 9.2 times that during 0 - 15 a, and it increased 8 times in 30 a; the content of HJCO3 was decreased at annual rate of 1.7 mg•kg−1; the content of NO3 reached about 1038 mg•kg−1 in the soil of 30 a, 25.7 times compared to that in open field soil; annual growth of NO2 content was 0.85 mg•kg−1; and annual growth of SO2-4 content was 33 mg•kg−1.
