摘 要:对贵州植烟土壤有机质、氮磷钾、p H等烟草生产的肥力适宜性进行了系统的调查研究。结果表明 ,植烟土壤的有机质、速效氮、速效磷、速效钾平均含量分别为 2 9.5 g/ kg、5 0 .36 mg/ kg、18.1mg/ kg和4 6 .6 mg/ kg,适宜或最适宜植烟土壤的比例分别占 5 5 .4 %、73.7%、4 3.6 %和 39.5 %。植烟土壤 p H分布在适宜及最适宜范围内的土壤占 6 6 .7%。根据贵州植烟土壤的养分现状 ,提出了优质烟叶生产的植烟土壤管理措施。This paper has made the systematic study on adaptability of fertility characteristics for tobacco-planting soils in Guizhou province. The results indicate that average contents of organic mater, available nitrogen, available phosphorous and available potassium are 29.5 g/kg,50.36 mg/kg, 18.1 mg/kg and 46.6 mg/kg respectively in tobacco-planting soils, and the soils with most suitable or suitable for tobacco-planting account for 55.4%, 73.7%, 43.6% and 39.5% respectively. And the proportion of pH value with most suitable or suitable for tobacco-planting soils account for 66.7%. Furthermore, based on the adaptability, the management methods of tobacco-planting soils for quality tobacco production are provided.
