我国经济林研究主要进展及有待突破的关键技术

经济林是我国森林资源的重要组成部分,具有较好的生态、经济和社会效益,在促进农村经济发展和山区农民增收中发挥着重要作用。笔者在全面介绍我国经济林产业发展现状的基础上,从经济林种质资源收集与利用、良种选育、丰产栽培机理机制和经济林产品加工利用等方面综述各领域的主要研究进展。提出基因编辑与分子设计育种技术、利用微生物培肥地力新技术、智慧林业理论与技术、提高抵御非生物胁迫能力技术、优化光合作用提高光能利用率新技术,以及经济林高附加值产品研发技术是未来经济林研究有待实现突破的关键技术。

A review of non-wood forest research in China and the potential development of key technologies

Non-wood forests are an important part of forest resources in China, which are associated with ecology, economy and social benefits. Non-wood forests play important roles in promoting the rural economic development and increasing farmers’ income in mountainous areas. Based on the comprehensive introduction of the development status of non-wood forests in China, this study summarizes the main research progress in various fields, including the collection and utilization of germplasm resources of non-wood forests, selection and breeding of improved varieties, mechanisms of high-yield cultivation, and processing and utilization of non-wood forest products. We propose that the key technologies for future non-wood forest research that will achieve technological breakthroughs are genome editing and molecular design breeding, using microorganisms to improve soil fertility, intelligent forestry, improving the ability to resist abiotic stress, optimizing the photosynthesis and improving the utilization rates of light energy, and the higher value addition products of non-wood forests. This review will provide useful information for non-wood forest industry development in China.
