摘要
本文根据川西南主要烟区土壤近 200 个样本的测试数据,对该地区烟田土壤有效态微量营养元素含量状况及分布规律进行分析和探讨。结果表明:川西南烟区土壤有效 Cu、Fe、Mn 含量较丰富和极其丰富,有效 Zn 含量较大面积上缺乏,整个烟区有效 B 极其缺乏。为川西南地区烟草种植的合理施肥提供了依据。
Available microelements of 200 soil samples taken from tobacco soils in Southwest Sichuan were measured. Distribution patterns of their contents were discussed. The results show that in the tobacco soils in Southwest Sichuan, available Cu, Fe, and Mn are quite rich. Most of the soils are deficient in available Zn. The whole tobacco region is extremely low inavailable B. The findings of the research can be used as guidelines for optimal fertilization of tobacco.
