为提高云南干旱地区芒果园管理技术和水平．通过田间试验研究不同豆科植物行间间作后土壤养分的变化。结果表明：生草间作两年后，0～60cm土壤有机质降低；20-60cm土壤全氮和全磷增加，0～60cm土壤全钾增加；新诺顿豆和大翼豆将20-60cm土壤pH从酸性提高至中性：饭豆＋绿肥提高了0～60am土壤碱解氮和速效磷，饭豆＋绿肥、饭豆以及田箐提高了0～60cm土壤速效钾。试验所选生草可以增加20-60cm土壤全氮、全磷和全钾的积累，饭豆＋绿肥轮作可以有效提高0～60cm土壤碱解氮、速效磷和速效钾含量。

In order to improve management level of mango orchard in dry regions of Yunnan, by field experiment, this paper researched the change of soil nutrient after intercropping different legume plants. Results showed that after grass-interplant two years, soil organic matter lowed at 0 to 60 cm layer. Soil total nitrogen and total phosphorus increased at 20 to 60 cm layer, soil total potassium increased at 0 to 60 cm layer. The two treatments Neonotonia wightii and Macroptilium lClthyroides improved soil pH of 20 to 60 cm layer, which raised from acid to neutral. The treatment Lablab purpureus + Viciavillosa rothvar improved soil alkali-hydrolyzable nitrogen and available phosphorus at 0 to 60 cm layer, the three treatments Lablab purpureus + ViciaviUosa rothvar, Lablab purpureus ~ind Sesbania cannabina Pers improved soil available potassium at 0 to 60 cm layer. The grasses of this experiment raised the level of soil total nitrogen, total phosphorus and potassium at 20 to 60 cm layer, it was efficient to improve soil alkali-hydrolyzable nitrogen, available phosphorus and potassium at 0 to 60 cm layer in Lablab purpureus / Viciavillosa rothvctr rotation system.
