微量元素对烤烟产量影响的研究

Effect of Micronutrients on Yield Of Flue-cured Tobacco

以钢、铁、锌、锰、硼等五种微量元素溶液三次喷酒烟株共３６个处理的产量结果指出，总的趋势是喷洒这些微量元素作微肥有增产烟叶的作用。产量高的优化组合的各微肥用量在中等水平以上，五因子按影响产量的贡献率大小的顺序为铁＞硼、铜＞锌＞锰。

Five micronutrients (Cu.Fe. Zn. Mn.B) fluid were spreaded on flue-cuted tobacco. The yield results indicated that the five micronutrients to yield in the order of importance was Fe>B, Cu>Zn>Mn. One and two factors analysis showed that spreading micronutrients fluid was an increasing yield treatment for flue-cuted tobacco.
