- Abstract:
- The canopy characteristics and the relative light radiation of Zanthoxylum bungeanum under different site conditions were studied by Hemi-iew canopy hemispherical co-ordinate system in Hancheng Region. Analysis of different site conditions of Zanthxylum bungeanum canopy characteristics and soil nutrient status and its changes in the relationship with canopy was carried out. The results showed that the ellipsoidal leaf angle distribution parameter (ELADP), the average leaf angle (MLA), indirect site factor(ISF), direct site factor(DSF)and global site factor(GSF) of Zanthoxylum bungeanum in South slope level terrace were higher than that in North slope level terrace and flat ground. Zanthoxylum bungeanum in South slope level terrace intercepting the solar radiation ability was the strongest, the flat ground next best, north slope level terrace is the weakest. The lands under different site conditions were lack of organic matter and available phosphorus, especially in flat ground; the available nitrogen is in the medium level; the available potassium element was rich. Therefore, the organic fertilizer and the phosphate fertilizer investment should be increased, which could enhancethe output and quality of Zanthoxylum bungeanum.
