^(59)Fe在4种花卉栽培基质中的行为

DYNAMIC OF ^(59)Fe IN DIFFERNT SOILS FOR FLOWER PLANTING

利用示踪技术研究了59Fe在 4种花卉栽培基质中的动移 ,结果表明 ,59Fe在 4种基质中的积累由高到低的顺序为 :含 2 0 %河砂的腐质土 >仙土 >草碳土 >植金石 ,且一旦积累很难用浇水的方法使其彻底排出。同时 。

Movement of 59Fe in 4 types of soils for flower planting were studied. The results indicated that the accumulation of 59Fe in 4 types of soils were in the order of muck soil>Xian soil>Caotan soil>Zhijinshi soil. Removal of accumulated 59Fe in soil with irrigation was difficuty, but 59Fe in soil could move onto soil surface with evaporation.
