摘要
在磷酸根、硅酸根存在下以 2 %硝酸镧作机体改进剂 ,测定了酵素菌肥中多种金属元素的含量 ,各元素的平均回收率分别为 :K 98 69% ,Ca 10 0 3 7% ,Mg 97 81% ,Na 96 0 6% ,Cu98 2 6% ,Fe 96 45 % ,Zn 99 78% ,Sr 93 5 4% ,Li 94 2 2 %。方法简便 ,快速可靠 。
The content of metal elements in ferment fertilizer was determined in the existence of PO 4 3- and SiO 3 2- ,with 2% La(NO 3) 3 as matrix modifier.The recovery rates were obtained.The nutritional effects of these metal elements were analyzed.
