An Experimental Study on Demonstration Afforestation in Sandy Zhongnanshan Mountain Areas

Acacia dealbata Link. was selected as a major afforestation species according to its ecological biology and soil texture of the sandy Zhongnanshan Mountain areas which had been supposed to be unplantable because of the poor site factors and preceding silvicultural failure for several times.Certain hypernormal methods were adopted by means of 3 technics, i.e., applying inorganic fertilizers rationally, distributing nutritive cubs properly, and using root inducing powder(No.3 ABT) appropriately.These methods produced a marked afforestation effect, whereupon they technically and methodologically demonstrated scientific, rational and practical prospects for future afforestation in this county's wasteland of 26 700hm². of the same kind.
