摘  要:
为给黔南山地优质烟叶平衡施肥和烤烟专用肥配方提供参考数据,2009-2010年共采集了黔南烟区9个产烟县(市)具有代表性的植烟土壤样品1 250个,进行土壤pH和有效养分含量分析。结果表明:黔南烟区植烟土壤pH值大部分处于适宜范围,有机质含量总体处于中等或丰富水平,碱解氮、有效磷含量属于丰富水平,有效钾平均含量处于中等水平。建议,在生产过程中,偏酸性土壤施用适量的石灰调整土壤酸碱度,有机质含量丰富与极丰富的土壤可在短期内不施或少施有机肥;氮、磷、钾养分供应需遵循控氮、稳磷、提钾的原则,增施钾肥,提高土壤有效钾含量。

摘  要:
In order to provide reference data for balanced fertilization of high quality tobacco and special fertilizer formula for tobacco,1 250 soil samplesat 0~20 cm depth were collected from nine counties in Qiannan tobacco farming area,soil pH and available nutrients were detected and analyzed.The results showed that pH of most tobacco-grown soils wrere in a suitable range.Organic matter content in soil was moderate or rich.Moreover,contents of available N and P were high,while average content of available K was moderate.Therefore,it was necessary to regulate acidic soil pH by using lime.Organic fertilizer should be not applied or less applied in soils rich and very rich in organic matter.However,N,P,K nutrients should follow the principle of controlling N,Maintaining P and Increasing K' to increase available K in soil.
