毛乌素沙地文冠果植苗造林试验

为了使文冠果造林更好发挥其应有的生态功能,与产业经济有效结合,须精确把握文冠果造林的每个环节。通过对文冠果进行造林地选择、造林密度确定、栽植穴大小以及肥料的施用等方面试验研究,结果表明:文冠果宜在沙壤、壤土性质的立地条件造林,避免在排水不良的低洼地、盐碱地造林。荒山生态造林密度宜在420~1120株·hm^-2范围内;水分条件较好的地段,生态经济林造林密度在840~1665株·hm^-2范围内,栽植穴80 cm×80 cm为宜。栽植前穴底施用腐熟的粪肥,促进苗木生长。

Experimental Study on Xanthoceras sorbifolia Seedling Planting in Mu Us Sandy Land

In order for Xanthoceras sorbifolia to be able to better play its due ecological function after afforestation,and to effectively combine with the industrial economy,it is necessary to accurately grasp every aspect of afforestation.The experimental research were conducted from several aspects such as the selection of afforestation of Xanthoceras sorbifolia,the determination of afforestation density,the size of planting hole and the application of fertilizer.Result shows that Xanthoceras sorbifolia should be afforested in sandy soil and loamy soil,avoiding low-lying land and saline-alkali land;the afforestation density of barren mountain should be in the range of 420-120 plant·hm^-2,and the water condition is good to build an eco-economic forest with an afforestation density in the range of 840-1665 plant·hm^-2,planting holes of 80 cm×80 cm is appropriate.Before planting,rot manure is applied at the bottom of the hole to promote seedling growth.
