摘　　要：2009年7月采用随机区组试验设计进行旱冬瓜山地造林施肥试验,2011年1月进行旱冬瓜幼林高、径生长量调查,分析结果表明:进行山地造林时施底肥能显著促进旱冬瓜幼林的高、径生长,施肥幼林高生长高出对照43.5%,径生长高出对照92.7%;以施N肥的作用最为显著,尤以150 g表现最好,林木的高、径平均生长量分别高出对照85.2%和165%.In July 2009, By using randomized block design, manurial experiment on the mountain afforestation of Alnus Nepalensis was conducted, and in January 2011, by surveying the growth status of high and diameter of young Alnus Nepalensis forest, the results show that ： About mountain afforestation, applying base fertilizer could significantly promote the growth of Alnus Nepalensis on high, diameter, the height growth of young forest were higher by 43.5% , 92.7% of diameter growth than the control; The effect of N fertilizer application is most remarkable, especially at the 150 g performed the best, the high and diameter increment were higher than that in control by 85.2% and 165%.
