Comparative Study on Afforestation Growth of Eucalyptus uro-phylla ×E.grandis Seedlings from Different Sources
摘要
Abstract
In order to clarify the growth difference of Eucalyptus urophylla XE.grandis clone DH32-29 seed-lings from different sources at the young stage(1-3 years old)after afforestation,and provide scientific the-oretical basis for the selection of high-quality seedlings and the improvement of quality,yield and efficiency,the E.urophylla X E.grandis clone DH32-29 seedlings(BG)and the E.urophylla XE.grandis clone DH32-29 seedlings(NBG)were used as the research objects.The differences of DBH,tree height,biomass,carbon storage and productivity of different seedling afforestation stands in three regions of northwest,central and southern Guangxi were compared.The results showed that at the age of 2 and 3 years,the average DBH,biomass per plant,carbon storage per plant and productivity per plant of E.urophylla ×E.grandis in BG stand were significantly higher than those of NBG stand(P＜0.05).The biomass,carbon storage and pro-ductivity of arbor tree layer of BG stand were higher than those of NBG stand.The difference was small at 1 year old,and the difference increased at 2 years old,but it did not reach a significant level(P＞0.05).The difference at 3 years old reached a very significant level(P＜0.01).The effect of increasing yield by afforest-ation with high quality seedlings from clear sources is more obvious.关键词
