施硼对烤烟产量和品质的影响研究

对桃源植烟土壤硼素普查结果表明,植烟区土壤硼含量平均值为0.26 mg/kg,普遍低于烟株正常生长所需的有效硼含量.试验在严重缺硼的黄壤地施用不同量硼肥,研究施硼对烤烟生长及产质量的影响.结果表明施用一定量的硼肥可以促进烤烟的生长发育,使烤烟化学成分更趋于协调,提高中上等烟比例,显著提高烤烟产质量.以施用硼肥22.5 kg/hm2时的效果最好.

Effects of Applying Boron on Yield and Quality of Flue-cured Tobacco

The results from general survey of boron in tobacco-planting soil in Taoyuan indicated that the average boron content in tobacco-planting soil was 0.26mg/kg,which lower than tobacco-plant's need for regular growth.The experiment of applying different amounts of boron fertilizer to the yellow soil that lack of boron seriously was conducted to study the effects of applying boron on growth,yield and quality of flue-cured tobacco.The results showed that applying certain amount of boron fertilizer could promote the growth of tobacco,make tobacco's chemical compositions tending to be coordinated,enhance the proportion of superior tobacco and increase the yield and quality of tobacco obviously.When applying boron fertilizer of 22.5 kg/hm2,the result was the best.
