Effects of Afforestation Modes on the Growth of Xanthoceras Sorbifolia and Soil Microenvironment
This article uses three different afforestation models of Xanthoceras sorbifolia through experimental planting,namely sea-buckthorn+Xanthoceras sorbifolia mixed forest,black locust+Xanthoceras sorbifolia mixed forest,and pure planting Xanthoceras sorbi-folia forest.Detailed data statistics and comparative analysis were conducted on the tree height,ground diameter,crown width,soil or-ganic matter content,available phosphorus content,available potassium content,and available nitrogen content of Xanthoceras sorbifo-lia,as well as soil capillary porosity and non capillary porosity.The comprehensive comparison results show that,relatively speaking,the height of the mixed forest's Wenchuan fruit trees is higher,and the ground diameter and crown width are significantly higher than those of pure planting Wenchuan fruit trees.Among them,the mixed model of seabuckthorn and xanthoceras sorbifolia has obvious ad-vantages in tree height,ground diameter,and crown width.Data comparison shows that the soil bulk density of the two mixed forests is significantly lower,and the content of soil organic matter,available nitrogen,available potassium,and available phosphorus is signifi-cantly higher.From this,it can be seen that under the mixed planting mode,the growth and soil improvement of the fruit trees of Corol-la are better,making it a relatively more suitable afforestation method.
