阳坡山地花椒园的立地条件和丰产试验

MICROCLIMATE AND HIGH-YIELD TEST IN FLATSPINE PRICKLYASH GARDEN ON THE SOUTH OF A HILL

阳坡山地花椒园光热充足,但土壤水分、养分条件较差,因而,限制了单株产量。采用园地覆膜、尿素叶面喷肥技术措施能明显提高单株产量,是石灰岩山地花椒园的重要增产措施。

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.
