摘要
为实践"近自然林业"经营技术的应用效果,对红锥幼林开展近自然抚育和常规抚育对比试验,分析近自然抚育方法对幼林生长及林地土壤肥力的影响,结果表明:采用近自然抚育技术经营红锥幼林,林地的土壤肥力有一定的改善效果,表现在土壤水分物理性质得到改善、土壤养分含量有所增加。Ⅲ类地的改良效果优于Ⅱ类地,土壤表层比土壤深层的改良效果更明显;同时促进了红锥的生长,林分生长量有不同程度的提高,2年生林分树高、地径、冠幅比常规抚育的林分分别提高2.70-7.06%、2.94-10.0%和3.85-4.17%,尤以Ⅲ类地的近自然抚育经营的促进生长的效果更为明显。
To practice the application effect of ＂ close-to-nature forestry＂ management technique,the close-to-nature and traditional tending methods for Castanopsis hystrix young forest were tested and the effects of close-to-nature tending on the young forest growth and forest soil fertility were analyzed,The results showed C,hystrix young forest managed by the close-to-nature tending technique improved the forest soil fertility,It was shown in the improvement of soil water physical properties and the increase of soil nutrient contents; Class Ⅲ soil improved better than that of class Ⅱ; The method of close-to-nature tending also improved the forest growth and the forest stand growth increased in vary degree,For2-year-old forest,the tree height,ground diameter and canopy increased 2.70 to 7.06%,2.94 10.0% and 3.85 4.17% respectively,compared to the traditional tending method,Especially the forest growth was remarkable tended by the close-to-nature method.
