The invention discloses a Zenia insignis and dalbergia odorifera mixed afforestation method in stony desertification regions. The method comprises cleaning a mountain and preparing land, processing seedlings, afforesting in a mixed manner, and performing tending management. The method specifically comprises: in autumn in the previous year of afforestation, performing manual cave-shaped land preparation, selecting Zenia insignis container seedlings of 5-8 months and dalbergia odorifera container seedlings which are older than or equal to one year old to afforest, using a star-like uneven-aged mixed plantation method, plantation density of a mingled forest being 1900-2600 plants/hm2, after afforestation, weeding, applying fertilizer, and tending. The method breaks a problem that a Zenia insignis pure forest has stony desertification in a seasonal manner because of fallen leaves in winter, and makes Zenia insignis and the dalbergia odorifera muturally promote growth, so as to improve vegetation coverage of stony desertification mountain areas, improve soil, and enhance water and soil conservation effect. The method maintains soil fertility, promotes growth of rare tree dalbergia odorifera trees in height and improves trunk quality, reduces investment in manual trimming of the dalbergia odorifera and arranging trunk auxiliary supports, accelerates vegetation recovery process in the stony desertification regions, and increases income of mountainous area people. The method has good social benefit and ecological benefits.
