The invention provides a method for afforestation in gobi by using hybrid broussonetia papyrifera, and belongs to the technical field of afforestation. The method comprises the steps of leveling the land, conducting ditching, digging field planting holes, applying mixed fertilizer and a water retaining agent at the bottoms of the holes, planting nursery stocks, making transverse ridges and conducting watering. According to the method, the hybrid broussonetia papyrifera is utilized for afforestation in the gobi, and the tree species are selected properly, so that not only can local climatic conditions and site types be adapted to, but also crude protein woody feed can be obtained to solve the problem of lack of winter grass feed for herdsmen in the southern Xinjiang area; through the cooperation of planting ditches, the water retaining agent and the slow-release fertilizer, the efficiency of utilizing water and fertilizer is greatly improved, soil replacement is not needed, the cost isreduced, a large area of marginal land is utilized, and an extremely important role is played in local ecological environment protection. By means of the method, one month after planting, the sprouting rate of the nursery stocks is counted to be 97% or above, the afforestation survival rate of the nursery stocks is counted to be 95% or above in the later period, the average growth height of the nursery stocks reaches 80 cm or above, and harvesting can be conducted 2-3 times every year.
