为了研究亚热带作物的生命活动与内在条件和外界环境的关系,全苏茶及亚热带作物研究所在1957年从建立同位素实验室开始,就着手用放射性同位素C~(14)、P~(32)、S~(35)、Ca~(45)、Sr~(90)等进行试验。结果查明了培养元素和有机化合物在茶树——土壤系统中的吸收、分配和转化的规律性。采用放射性同位素C~(14)可以研究有机物质在芽梢中季节变化的动态,同时也可以揭示在茶树生长期间光
In order to study the relationship between the life activities of subtropical crops and the internal conditions and the external environment, the Institute of All-Sucha Tea and Subtropical Crops started with the establishment of isotope laboratories in 1957 and started to use radioisotope C 14, P 32, , S ~ (35), Ca ~ (45), Sr ~ (90) and so on. The results identified the regularity of uptake, distribution and transformation of cultivated elements and organic compounds in the tea-soil system. The use of radioactive isotope C ~ (14) can study the dynamics of seasonal changes of organic matter in buds, and also reveal the light
