摘要:
<正>我国经济连续高速增长,促进了人造板工业的飞速发展。要保持人造板工业又好、又快地可持续发展,必须坚持改革开放、开源节流,发展循环经济,进行自主知识创新,积极适应全球经济一体化发展趋势,协调和优化协会、学会和质量监督部门的管理方式,探讨节能、减排、提高综合利用率的生产模式。
Abstract:
In this paper, the appropriate growth traits and optimum age of early selection of hybrid pine (Pinus elliottii vat. elliottii (PEE) x P. caribaea var. hondurensis (PCH)) through family selection were studied. The estimated parameters of early selection were height and diameter at breast height (DBH) measured from this family test trail established in Taishan Hongling Seed Orchard of Guangdong. There were 18 families included. Height and DBH was measured every year (except the 7th year after planting) at the second year after planting. The individual volume was calculated according to the value of height and DBH. The last investigation was taken in 2005 with 10-year old. The results showed that there were extremely significant differences in height, DBH and volume among the test hybrid families. It had very strong and stable juvenile-mature genetic correlations. The growth correlation was mainly controlled by heredity, and early selection was effective. There were extremely significant correlations among height at age of two, DBH at age of three, volume at age of three after planting and the volume at age of ten. At the same time, selection efficiency was highest. Therefore, the early selection could be carried out by the strategy of two stages selection, e. g. the first stage selection might be conducted with height at the age of 2-year-old and the final selection completed with volume at the age of 6-year-old. The means of select were saved over 70%families.according to the height at first stage, and saved less than 35%families according to the volume at second stage.
