Analysis of Korean pine Mixed Forest Tending one day
Ding Quan-fu;Xijiang forestry station of Tonghua County in Jilin province;
This paper introduces the approximate same age of Korean pine mixed forest of different people day light transmission mode( uniform and ribbon),different light intensity( 30%,40%,50%) effect on growth and quality of Korean pine forest. The results show that,with the increase of the broad- leaved trees,thinning intensity pine DBH,tree height,plant dry weight and broadleaf tree DBH needles,precious hardwood proportion has increased; forest light and temperatures are rising. The Korean pine DBH,volume growth and plant leaf dry weight increased obviously. 9A compared with the control group,low,Taka Hikaru strength,pine DBH increased by 17. 2%,26. 3% and 34. 8%,the dry weight of plant leaves were increased by 43. 3%,88. 4% and 90. 3%,Korean pine growth of volume increased respectively 23%,71.6%,96. 1%. The comprehensive evaluation of tending effect,in the same light intensity,uniform light scored higher than narrowband transmission; in the 3 light intensity,uniform medium light intensity( 40%) scored the highest. Light transmittance felling is more suitable.
