吉林省西部葵花产区土壤理化性质与作物品质灰关联分析

Gray Relational Analysis on Soil Physical and Chemical Properties and Crop Quality of Sunflower-producing Areas in the West of Jilin Province

运用灰关联分析方法,对吉林省西部葵花种植区土壤理化性质与作物品质的关联程度进行研究。结果表明,3个工作区的葵花品质均与土壤机械组成、盐碱化程度关联较大,其中农安工作区的葵花品质与土壤有机质、CEC、盐基总量、交换性钙关联程度较高,大安工作区与通榆工作区的葵花品质与CEC关联程度较高。

Gray relational analysis method was used to study the extent of the association of oil physical and chemical properties and crop quality of sunflower-producing areas in the west of Jilin Province. The results indicated that the relation between sunflower with soil mechanical composi- tion and salinity is larger in the three areas, and in Nong＇ an work area, sunflower quality is associated higher with soil organic matter, CEC, to- tal amount of base, exchange of calcium, and in Da＇ an and Tongyu , the sunflower quality is associated higher with CEC.
