为了寻求改善腾冲烟区火山灰土壤母质条件下的植烟土壤酸化严重、镁含量不足的方法，通过大田试验研究了不同类型镁肥对土壤pH、养分、土壤微生物、土壤酶活性的影响。结果表明，施用白云石粉为土壤补充镁元素（土壤有效镁含量提高13.07~20.36 mg/kg）的同时能够改善土壤的酸化程度，并且该肥料在腾冲当地可以大量开采，成本廉价。因此，在腾冲烟区水田环境中，建议施用白云石粉作为补充镁素、改善土壤酸化的肥料。而不再施用硫酸镁以及生石灰来补充镁肥以及改善土壤pH。

In order to explore approaches for improving severely acidified and insufficient magnesium (Mg) volcano ash soils with tobacco planting in Tengchong, Yunnan province, field experiments were conducted to investigate the effects of various Mg fertilizers on soil pH, nutrient, soil microorganism, and soil enzyme activity. The results showed that application of dolomite powder could increased soil available Mg content 13.07-20.36 mg/kg, reduce soil acidification. The Mg fertilizers can be produced locally at low cost. Therefore, dolomite powder should be recommended to improve soil acidification, instead of magnesium sulfate or quick lime in Tengchong.
