【Abstract】 Despite the sufficiency of light and heat, the soil moisture and the nutrients on the south side of a hill are inadequate for the garden growing of flatspine pricklyash (Zanthoxylum bungeanum). As a result the yield of the individual plant is kept low.Fortunately, this problem can be solved by covering the gardenland with plastic film and by spraying urea solution on the leaves. It has been tried out that the technique is applicable to the production of flatspine pricklyash in limestone mountainous areas.更多还原
