以生长在3种长江滩地类型(江滩、洲滩、湖滩),3种栽植密度(3 m×4 m、4 m×5 m、5 m×6 m)下的3个品系速生人工林杨树木材[欧美杨无性系72杨(Populus×euram ericacv.I-72/58)、美洲黑杨无性系63杨(P.deltoidescv.I-63/51)和69杨(P.deltoidescv.I-69/55),以下简称72杨、63杨和69杨]为对象,在分析不同培育措施条件下人工林杨树木材材性的基础上,根据最终用途对杨树材性的要求进行评价,从而提出适宜于不同最终用途的最佳培育措施。结果表明,长江滩地杨树用于作建筑类材时,63杨和69杨为相对适用于作建筑类材的品系,3m×4 m是培育建筑类材的最佳栽植密度;对于纸浆材来讲,洲滩上宜选择63杨,江滩和湖滩上宜选择69杨在4 m×5 m栽植密度下培育;对于单板类人造板材来讲,宜选择72杨和69杨以3 m×4 m栽植密度来培育。
Three fast growing plantations were planted in three types of Yangtze River beach land (river beach, beach, lake beach), three planting density (3 m × 4 m, 4 m × 5 m, 5 m × 6 m) Poplar wood [Populus × euram ericacv. I-72/58, P. deltoides cv. I-63/51 and P. deltoides cv. I -69 / 55), the following referred to as 72 Yang, 63 Yang and 69 Yang], based on the analysis of wood material properties of poplar under different cultivation measures, according to the final use of poplar wood material to evaluate the requirements of Put forward the best breeding measures suitable for different end uses. The results showed that when poplar was used as building materials in the Yangtze River beach, the 63 Yang and 69 Yang were relatively suitable for the construction of building materials, 3m × 4m is the best planting density for building construction materials; for the pulp material Say, the beach should be selected 63 poplar beach, beach and beach should choose 69 Yang planted at 4 m × 5 m density cultivation; for the veneer sheet is concerned, 72 Yang and 69 Yang should be selected to 3 m × 4 m planting density to nurture.
