摘要
在我国主要烟区土壤养分普查的基础上,系统分析了植烟土壤主要养分状况及其在主要产区的分布规律,指出了我国植烟土壤存在的主要问题。结果表明,我国主要植烟土壤速效磷、交换性钙、镁,以及微量元素锌的含量尚丰富;本次普查一半区域土壤pH值不适宜烤烟生长,土壤速效氮含量也较高;我国植烟土壤有机质总体偏高;速效钾、有效硼全面缺乏。文章提出我国今后在烤烟施肥中应注意的问题。
Based on soil nutrients survey in major tobacco production regions of China, the main nutrients condition in soil and distribution characteristics in different production regions were discussed. The key problems in soil were indicated. The results showed that the Olsen-P, exchangeable calcium and magnesium and micronutrient -zinc was enrichment in soil. The pH of soil in half region was unsuitable for tobacco growth. The available nitrogen and the organic matter was superfluous. The available potassium and boron was deficiency in general. The advice was given for tobacco fertilization in China.
