摘要: 采用田间定点取样、定期播种与收获的方法,研究稻米品质与四川盆地区主要土壤生态因子之间的关系,结果表明:①稻米品质各性状及综合品质不同程度地受海拔高度、质地、养分含量等因子的影响,不同土壤生态因子对稻米各品质性状及综合品质的影响不一致,利用偏相关分析较单相关更能准确地反映两个变量的线性程度;②从单相关分析结果来看,海拔高度、物理性粘粒、粗粉粒、有机质、有效铜、有效铁、有效锰含量是影响稻米品质的主要土壤生态因子;从偏相关分析结果来看,海拔高度、耕层厚度、有机质、全氮、碱解氮、有效铜含量是影响稻米品质的主要土壤生态因子。

Abstract: Adopting the method of pointed sampling, timely planting and harvesting in the field, it studied the relationship between rice quality and the eco-factors of main soils in Sichuan Basin Area. The result indicates that:①Each character of rice quality and general quality are influenced, to some degree, by height above sea level texture and content of nutrient; the influence on each character of rice quality and general quality by different soil eco-factors disagree, the partial correlation analysis can even more correctly show the linearity degree of two variables compared with simple correlation analysis; ②Based on the results of simple correlation analysis, height above sea level and the content of physical clay coarse silt organic matter available cuprum available iron available manganese are the main soil eco-factors which influence the rice quality; ③Based on the results of partial correlation analysis,the height above sea level, thickness of cultivated layer, the content of organic matter, total nitrogen available and nitrogen available cuprum are the main soil eco-factors which influence the rice quality.
