居住在中国云南省独龙江流域的独龙族，长期以来有一种旱冬瓜农林混作模式，通过封同一地块的玉米地、3年生旱冬瓜林地和6年生旱冬瓜林地进行调查、取样分析，结果表明，6年生旱冬瓜农林混交模式在固氮、改善土壤肥力、促进生态恢复方面比玉米地和3年生旱冬瓜农林混交模式好。
The DU Long Nation have a farming-woods mixing modes over a long period of time, where they inhabitancy in the DU Long River drainage area of Yunnan province in China. Through the research and sampling analysis to the same plot that is cornfield, three years＇ Alnus nepalensi D. Don and six years＇ Alnus nepalensi D. Don. The result on, the six years＇ Alnus nepalensi D. Don is the best to another modes at the three aspects which include the nitrogen fixation, improve soil fertility and accelerate zoology renew.
