毛竹是我国森林资源的重要组成部分,毛竹的分布范围广,有着悠久的栽培历史,成为南方林业中的巨大森林资源,为山区的发展带来重要的经济效益。但根据现有毛竹培育现状来看,我国仍有大部分毛竹培育地有待进一步开发,对于毛竹经营的培养措施也需要进行技术上的革新。主要对毛竹经营管理措施进行综述性研究,然后针对毛竹特点,对毛竹的丰产科学技术进行实验性探讨,为毛竹的培育措施提供了有效依据。 Moso bamboo is an important part of forest resources in our country. Moso bamboo has a wide range of distribution and a long history of cultivation. It has become a huge forest resource in southern forestry and has brought important economic benefits for the development of mountainous areas. However, according to the status quo of existing bamboo cultivation, there is still a great majority of bamboo cultivation areas in our country to be further developed. Technical measures for the cultivation of bamboo business are also required. Mainly on bamboo management and management measures for a comprehensive study, and then for the characteristics of bamboo, Bamboo’s high yield science and technology to conduct an experimental study for the cultivation of bamboo provides an effective basis.
