    摘要:

    为提高云南省罗平县烟区烤烟施肥的针对性,于2008年和2014年对烟区355个植烟土壤样点进行跟踪取样,运用肥力适宜性指数(SFI值),对土壤肥力适宜性进行综合评价,研究了土壤养分的时空变异特征。结果表明:①罗平烟区土壤pH和速效磷、速效钾、有效锌、有效硼含量适宜,有机质、碱解氮、有效镁和水溶性氯含量偏高;②罗平烟区大部分土壤处于“较好”和“中等”水平,肥力适宜性指数平均值为0.762 9,土壤肥力状况良好;③各乡镇土壤肥力适宜性表现出大水井乡>板桥镇>九龙镇>罗雄镇>阿岗镇>马街镇>钟山乡>旧基屋乡>老厂乡>富乐镇的趋势;④2008—2014年,烟区土壤有机质含量整体降低,pH和碱解氮、速效磷、速效钾、有效锌、有效镁、有效硼、水溶性氯含量以及肥力适宜性指数有所增高。

    Abstract:

    The soil nutrient contents in 355 soil samples of tobacco-planting area in Luoping of Yunnan were surveyed in 2008 and 2014 in order to improve the targeted fertilization. The soil fertility suitability were comprehensive evaluated by soil fertility index (SFI value) and the spatial and temporal variations of soil nutrient contents were studied. The results indicated that: 1) soil pH, rapidly available P, rapidly available K, available Zn and available B contents were at an appropriate level while organic matter, hydrolytic N, available Mg and water-soluble Cl– contents were higher. 2) The integrated fertility index of most tobacco-planting area in Luoping was in better and medium level, the average SFI value was 0.762 9 and soil fertility was in good condition. 3) The soil fertility suitability index in different areas was: Dashuijing>Banqiao>Jiulong>Luoxiong>A’gang>Majie> Zhongshan>Jiujiwu>Laochang>Fule. 4) From 2008 to 2014, the organic matter content reduced, while the pH value, content of hydrolytic N, rapidly available P, rapidly available K, available Zn, available Mg, available B, water-soluble Cl– and SFI value increased.
