尾巨桉无性系高密度造林试验初报OA
A Preliminary Report about High-density Afforestation of E. urophylla ×E. grandis Clones
以当前桉树生产上常用的造林密度1666株/hm^2为试验的最低造林密度,与5种更高造林密度作为构成本试验的6种不同造林密度的高密度试验,分析尾巨桉(Europhylla×E.grandis)试验林2年生时的林分密度生长效应。结果表明,不同密度处理间的林分生长量有极显著差异,密度越大,其林分树高、胸径、单株材积越小,林分蓄积量则随密度的增加而增大,这与其它许多桉树密度试验结果相似。但林分生长效应提早,可能是林分密度过高缘故,最后结果有待继续观测研究。
High-density tests of E. urophylla × E. grandis clones with six different kinds of afforesta- tion densities including the lowest density of 1666 strains/hm^2 which is common to be used in current production of eucalypt and five kinds of higher densities were done to analyze the growth effect of stand density in the 2-year-old test forest. The results showed that there were very significant differences a- mong stand growths of different densities. The higher…查看全部>>
