稀土农用是一项开发性新技术,近来稀土微肥已开始在茶叶生产上进行试验并推广和应用。由于稀土应用茶叶生产后,对其在茶叶上的残留量测定及分析等方面资料尚缺,是否符合饮料卫生标准尚无定论,不利于该生产技术的推广应用。为此,我们在现有资料基础上,于1987～1988年有重点地对该项目进行试验研究。试验材料和方法供试材料为河南商丘产的“常乐”和浙江嵊县产的“稀土复合肥”,试验设置稀土复合肥浓度300倍(A_1)和500倍(A_2);
Rare earth agricultural is a development of new technologies, the recent development of rare earth fertilizer has begun in the tea production and promotion and application. Due to the rare earth application of tea production, the determination of its residual amount of tea and other aspects of the information is still lack of conformity with the standard of health drinks is not conclusive, is not conducive to the promotion of the production technology. To this end, based on the existing information, we conducted a pilot study of the project from 1987 to 1988. The test materials and methods were “Changle” produced in Shangqiu of Henan Province and “rare earth compound fertilizer” produced in Sheng County of Zhejiang Province. The concentrations of rare earth compound fertilizer were set 300 times (A_1) and 500 times (A_2).
