在低丘红壤的茶园和果园四周,模拟自然生态群落结构,用20余个落叶树种和常绿树种进行混交,试验成功具立体结构的防护林,这种混交林带,能合理地利用空间,充分利用各层次的土壤肥力,增强各树种间的抗性,减少病虫害,增加林分产量和木材质量,还可改良土壤提高肥力,对茶叶和柑桔的防护效益也优于纯林。通过14年的研究,总结出一套实用的立体混交林带营造技术。
In the hilly red soil around the tea plantations and orchards, mimicking the natural ecological community structure, with more than 20 deciduous trees and evergreen species mixed to test the success of a three-dimensional structure of the shelter forest, the mixed forest belt, the rational use of space, make full use of All levels of soil fertility, enhance resistance among trees, reduce pests and diseases, increase stand yield and wood quality, but also improve the soil to improve fertility, the protective effect of tea and citrus better than pure forest. Through 14 years of research, summed up a set of practical techniques of building a mixed forest.
