| 摘 要： | 田间试验结果表明，喷施锌或碘后，在一定浓度范围内，白菜累积锌，碘量明显增加，最大累积最分别达到６２．２ｍｇ／ｋｇ和３．２ｍｇ／ｋｇ，白菜产量也有一定程度的增加，但是当锌、碘喷施量超过一定浓度后，对白菜会产生毒害作用，同时，喷施锌，碘对白菜硝酸盐含量，维生素Ｃ含量也有一定影响。

| Abstract: | The paper illustrated the effect of spraying Zn and I in plot experiment. The results showed that accumulations of Zn and I are increased by spraying Zn and I in specific range and the maximum accumulation of Zn and I were 62 2 and 3 32 mg/kg respectively and the yield of Chinese cabbage increased, too. But if the concentration of Zn and I was up to a threshold, the toxicity will be produced by both of the elements.In the mean time,the effect of spraying Zn and I on the quality of Chinese cabbage,such as nitrate and Vc content, was also studied too. |
