| 摘 要： | 适宜的土壤环境条件是烟草优质适产的基础，土壤养分直接影响烟叶品质。笔者对平顶山市6个主要烤烟产区的308个烟田土壤样品进行化验分析，总结各县市烟田土壤养分含量的特点。结果表明：平顶山市植烟土壤pH平均为6.93，有91.23%的土壤在5.5以上；土壤有机质平均含量为15 g/kg，速效氮、磷、钾的平均含量分别为91.6、12.6和108.3 mg/kg；土壤水溶性氯平均含量为21.2 mg/kg，有84.7%的土壤水溶性氯含量低于30 mg/kg。根据平顶山土壤养分状况，提出控氮、增磷、补钾的施肥策略。

| Abstract: | Good soil quality provides the probability for producing tobacco leaves with high quality. Its soil nutrient content influence the quality of tobacco leaf directly. This paper analyzed 308 soil samples from flue-cured tobacco fields in six main flue-cured tobacco production areas in Pingdingshan city. The characteristics of soil nutrient contents in tobacco fields of each county were analyzed in detail. The results showed that the pH values of 91.23% soil samples were above 5.5 and the average value was 6.9... |
