| 摘 要： | 在对安宁市八街、县街、草铺、禄脿4个植烟区主要土壤养分检测分析基础上,探讨了安宁植烟区域土壤的主要养分特征。结果显示:安宁烟区植烟土壤的酸碱性以弱酸性至中性为主,部分土壤略偏碱性;有机质含量中等至丰富,速效氮和速效磷含量较高,土壤速效钾含量为中等偏下水平,部分土壤速效钾处于低等至缺乏水平。因此,安宁主要植烟区应采取"稳氮磷、提钾、注意氮肥施用时间、提高磷钾肥利用率"的施肥对策,以实现烤烟优质高效生产。

Analysis of Soil Nutrient Characteristics in Tobacco Planting Area of Anning |
| |
| Abstract: | The study was conducted to study the soil nutrient status in tobacco planting areas in Anning.The soil samples,collected from Bajie,Xianjie,Caopu,Lubiao four townships of Anning County,were analyzed.The results indicated that most soils in tobacco planting areas of Anning were weakly acidic and neutral,and some were alkelescent.The contents of organic matter were in the medium level to high level.The soil was found to be rich in available nitrogen and available phosphorus.The available potassium contents in most of soils were in the medium level to low level,and some were in the low level to lack level.On the basis of these results,it can be suggested that the N,P and K content along with paying attention to nitrogen fertilization time and raising the utilization ratio of phosphate,potassium fertiliser need to be taken into consideration and corrected by proper fertilizer management to sustain the high productivity of the flu-cured tobacco. |
