| 摘 要： | 为毕节市烟叶生产平衡施肥提供依据,对毕节市2014-2016年主要烤烟种植区七星关、大方、黔西、织金、纳雍、金沙和威宁土壤养分进行调查分析.结果表明:毕节市植烟土壤pH平均值尚处适宜范围,但黔西和织金碱化土壤占比较大,3年均值均大于7.00;有机质、全氮和速效磷含量总体偏高;速效钾含量整体呈增加趋势,除2015年大方、2014年和2015年威宁外,其余均100%达极高水平.毕节市植烟土壤能够满足烤烟的生长,但是要合理施肥,总体上把握控氮、适磷、稳钾的用肥原则.

| Abstract: | To provide basis for tobacco balanced fertilization in Bijie.The soil nutrients in tobacco-planting soils in Bijie City, including Qixingguan District, Counties of Dafang, Qianxi, Zhijin, Nayong, Jinsha and Weining, were investigated and analyzed.Results: The average pH value of tobacco-planting soils was still within the appropriate range, but alkalized soil accounted for a large proportion in Qianxi County and Zhijin County, the three-year average value was over 7.00;the contents of organic matter, total nitrogen and available phosphorus were relatively high in soil;In addition, an increasing trend was also found in the content of available potassium, and 100% of them reached an extremely high level except Dafang in 2015,weining 2014 and 2015.The tobacco-planting soils in Bijie City were suitable for tobacco growing on the basis of reasonable fertilization according to the principle of "controlling nitrogen, making optimum phosphorus and firming potassium". |
