基质浸润施硼对烟草硼吸收及其生长发育相关指标的影响

 以烤烟品种K326为材料，研究了基质浸润法施用硼肥对烟草生长发育及相关生理生化指标的影响。结果显示：硼酸溶液浸润基质的处理，烟株各项农艺性状和生理指标表现好，烟株体内各器官营养比例最为平衡。表明在适宜浓度下，通过基质浸润增施硼肥可明显促进烤烟生长，相对于叶面喷施硼有用量少、操作简单、肥料利用率高的优势。

The Influence on Growth of Flue Cured Tobaccos, Boron Absorption and Related Indicators by Stromal Invasion of Boron Fertilizer

Flue cured tobacco variety K326 was taken as the material to study the stromal infiltration method of boron fertilizer application on tobacco growth and related physiological and biochemical indexes. The results showed that: the handle of using boric acid solution infiltration matrix, the agronomic performance of tobacco was the best, tobacco plant nutrition proportion of the various organs of the body was the most balance. Studies showed that in appropriate concentration, through stromal infiltration by boron could obviously promote the growth of flue cured tobacco, relative to the spraying boron have less dosage, simple operation, good effect of promoting the growth of the advantage.
