在非常干旱的1983年7月和8月,从20年生的 kastanka 和 kordia 甜樱桃品种上采取叶片,分析其 N、P、K、Ca、Mg、Zn、Cu、Mn、B、Mo 和 Fe 的含量。结果用方差分析和 t—测验进行统计分析,并对统计方法的极限进行讨论。向顶生的叶片 K、Ca、Zn、Mn、B 和 Fe 的含量减少。kordia 比 kastanka 的叶片含有较多的 Mg、Ca 和
In July and August of 1983, leaves of 20-year-old kastanka and kordia sweet cherry varieties were harvested and analyzed for N, P, K, Ca, Mg, Zn, Cu, Mn, B, Mo and Fe content. Results were analyzed by ANOVA and t-test, and the limits of statistical methods were discussed. The content of K, Ca, Zn, Mn, B and Fe to the terminal leaf decreased. Kordia kastanka leaves contain more Mg, Ca and
