白城市水稻种植区土壤的地球化学特征与水稻产量的相关性研究

Research on the relativity between the geochemical characteristics of the soil and the paddy yield in the paddy planting areas from Baicheng, Jilin province

吉林省白城市水稻种植区土壤的地球化学特征研究表明 ,土壤中的SiO2 、TiO2 、Al2 O3 、FeO、MnO和P2 O5等主要元素的含量与水稻产量具有正相关性 ,而CaO和MgO等主要元素的含量与水稻产量呈负相关性。土壤中的稀土元素含量和水稻产量呈正相关性。

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.
