Total Project On Seeds Of Garden Of Broadleaf Forest In Forestry Bureau Of Baishishan In Jilin Province

Jilin Province is the key place of origin of timber in China and has made significant dedication for economic construction in China for many years. Along with the performance of the natural forest protection project, the output of timber goes down to great extent, so the timber produced can't meet the demand of economic development. In order to resolve the contradiction, we should start with building the artificial forest, then, our primary assignment is to build the artificial forest with rapid speed of development, high augment of heredity, perfect quality of timber and steady expression of character. The most convenient and reliable channel is produce the suitable fine breed of timber to realize that target, while the best way to produce the fine breed is to build the seed garden of timber.Though the forest areas of Jilin Province have built part seed gardens of timber, the durability is weak because of only paying attention to the character of development and omitting the character of durability when choosing excellent seeds of tree. At present, most of the seeds of forestations in Jilin Province possess low quality of heredity and less character of rapid development, abundant production and perfect quality. Moreover, we only paid attention to conifer and omitted the broadleaf forest when choosing the seeds of tree for the seed gardens in the past of Jilin Province, and caused the problem of unitary variety. This paper gives the seed orchard design for broadleaf species of Baishishan forest bureau by means of modern forestry genetics breeding theory, puts out management scheme and productive task, and makes out the scheme of plus tree selection and techniques of established seed orchard, and takes the plan and design for base engineering, office setting and investment plan etc.The project is the application and practice of the hereditary breed theory and method of modern timber. After succeeding in performing the project, we will obtain unappreciable ecological and social benefit besides great economic benefit, and strongly push forward the development of forest industry and ecological construction affairs.
