Study On Provenance Trial And Silviculture Of Fokienia Hodginsii

This investigate subject from "ninth five" country scientific and technological project "study on high quality industry wood cultivate and high-efficient to utilize" ( number 96 - 011 - 03 - 03 - 02); "tenth five" country scientific and technological projects( number 2002 BA515B0104). Collaboration team of Fokienia hodginsii in Hunan Province according as bargain of "ninth five" country scientific and technological project, gone on collection of geography provenance, experimentation of breeding technology, provenance selection at breeding time, afforestation of provenance and family forest, provenance selection at child forest time, afforestation of plus tree subgeneration forest, afforestation of mixed forest, study of Natural Distribution and planting history, etc. Collectede ography provenance include of 8 province (Guizhou, Yunnan, Guangxi, Guangdong, Hunan, Jiangxi, Guizhou) 21 place. It is first that provenance trial of Fokienia hodginsii in Hunan province, main acording to traits of breeding and child forest time, studyed geographical variance of provenance, good provenance selection, and forest stand and individual selection based on provenance selection, found the base for genetic improvement and selection breeding. Based on the different nursery way experiment of container, open field and shade field. The main biological indexes as height, dimeter at ground level, number of lateral root and weitht of dry or fresh mass had significant difference by nursery way. The high yield nursery technology of open field interate with shade field was summarized which is suitable to spreaded. According to study afforestation technological of mixed forest, good provenance and family applied structure adjustment of tree species of complete forest stand and afforestation of merchandise forest base. Selected 31 plus tree, builded 0.27hm~2 collection nursery, it accumulated a lot of experience for established seed orchard.
