Ratio of sugar/nitrogen negatively correlated with seedbed soil fertilizing level, and the correlation coefficients were 0.9623 in alluvium soil and 0.9614 in hill soil. The results suggested that sugar and nitrogen metabolism were mainly controlled by soil fertilizing level.
秧苗糖氮比与床土培肥水平有着很好的相关性,冲积土和丘陵土两种床土条件下的相关系数分别为0.9623、0.9614,表明秧苗的糖氮代谢很大程度上受到床土肥力水平的控制。
