| Abstract: | In this paper the main fertility indexes of 3 987 paddy soil samples in Jianyang were determined.The results showed that the average soil acidity was 5.2±0.3(the partial acidity),the average content of organic matter was(34.9±6.4) g/kg(relatively rich),the average contents of available nitrogen,phosphorus and potassium were(185.9 ± 55.8) mg/kg,(18.9 ± 9.3) mg/kg,(89.2 ± 52.4) mg/kg respectively,the soils with the contents under-intermediate-level accounted for 73.7%. |
