| Abstract: | The research on the geochemical characteristics of the soil in the paddy planting areas from Baicheng in Jilin province indicates that the contents of SiO 2,TiO 2,Al 2O 3,FeO,MnO and P 2O 5 in the soil have positive relativity to the paddy yield, that the contents of CaO and MgO in the soil have negative relativity to the paddy yield, and that REE aboundances in the soil have positive relativity to the paddy yield. |
