摘要
分析了吉林省主要水稻种植区灌溉水源水质成分、水质成分与土壤成分相关性及水质物化特征对水稻产量的影响 ,得出吉林省水稻种植区灌溉水源水化学特征具有地带差异性 ,地表水中 p H值与水稻产量呈负相关 ,而 Cu,Zn等营养元素含量与水稻产量呈正相关 ;地下水中 Ca,Mg,Na及 HCO- 3,SO2 - 4和 Cl-等离子高含量对水稻产量具有抑制性。
Based on the comparative analysis of the water quality of irrigation,it is found that there is some regional diversity in the geochemistry features of the water resources in the main paddy planting districts in Jilin province.According to the analysis results of the correlation of the irrigation water quality with the paddy yield,it can be concluded that the content of pH in surface water is negatively related to paddy yield,but that of Cu,Zn are positively related to paddy yield.It further shows that the high content of Ca,Mg,Na,HCO - 3,SO 2- 4 and Cl - in groundwater restrain rice production.
