| 摘 要： | 2005、2006年采集了百色市8个产烟县有代表性的植烟土壤样品236个,并进行了土壤养分含量分析。结果表明,百色市土壤pH处于适宜范围,土壤有机质较为丰富,土壤速效氮、速效磷含量较高,土壤速效钾相对缺乏,土壤交换性钙、有效硫含量丰富,土壤交换性镁含量偏低。因此,在生产过程中,要遵循控氮、适磷、提钾原则,施用生物钾肥,提高土壤有效钾含量;注意增施镁肥,提高土壤交换性镁含量。

| Abstract: | A total of 236 tobacco-planting soil samples were collected from 8 tobacco-planting regions in 2005 and 2006.Soil nutrient contents were determined for these samples.The results showed that the pH values of Baise soils was appropriate to tobacco growth,soil organic matter content was high,the soil available N and P were slightly high,but available K was insufficient.Soil exchangeable Ca and available S were sufficient,but Mg is slightly low.Therefore,it is necessary to control N and P fertilizer,apply K fer... |
