Soil Geochemical Characteristics and Genesis of Selenium,Germanium and Strontium in the Northeast Towns of Pucheng County,Fujian Province
In order to master the content characteristics of selenium,germanium and strontium in the cultivated land of four towns in the northeast of Pucheng County,based on the 1∶10,000 agricultural geological survey and evaluation data of four townships in the northeast of Pucheng County,Fujian Province in 2018-2020,After the outliers are removed according to the mean±3 times standard deviation of the sampled data,The parameters of selenium,germanium and strontium content were counted again.The results showed:The selenium content ranged 0.049～0.699 mg/kg,and the arithmetic mean value was 0.193 mg/kg;The germanium content ranged 0.94～2.59 mg/kg,and the arithmetic mean value was 1.342 mg/kg;The strontium content ranged 12.40～290.30 mg/kg,and the arithmetic mean value was 70.42 mg/kg.By correlation analysis,pH value was negatively correlated with Se and Ge,and positively correlated with Sr.Se,Ge and Sr contents were different in different soil types,parent materials and land use types.Meanwhile,0.94 km2 of selenium-rich cultivated land was delineated.Germanium rich cultivated soil was delineated by 15.08 km2;The strontium-rich cultivated soil was delineated at 8.78 km2.Among them,the amount of selenium in the soil reached 46.53 km2,accounting for 55.27％of the surveyed area,The research area has a good potential for developing soil resources rich in selenium,germanium and strontium,and provides scientific basis for the agricultural structure adjustment,development of agricultural products rich in selenium,germanium and strontium,and planning land in Pucheng County in the future.
