摘  要:
本文通过在喀斯特山区的构树截干造林试验,讨论不同径级的构树其截干造林的初步效果,旨在为土层浅薄的石漠化山区造林提供理论依据及技术指导。从两年的调查结果来看,对文中设置的三个地径组(A1:d=0.5~1.0cm、A2:d=1.0~1.5cm、A3:d>1.5cm),虽然A1、A2两个地径组截干处理的构树在造林当年生长处于劣势,但造林第二年幼林植株的树高、地径、冠幅和生物量等生长指标的数据显示,三个地径组截干处理的造林效果均优于留顶处理。

摘  要:
Based on the experiment of afforestation with truncated stems of Broussonetia papyrifera in rocky desertification area,this page discussed the primary afforestation effects of Broussonetia papyrifera with different treatments(truncated and top-remainning) in 3 diameter classes(A1: d=0.5-1.0cm;A2: d=1.0-1.5cm;A3: d>1.5cm),in order to provide theoretical basis and technical guidance for afforestation in rocky desertification area.According to the results of the survey for two years,diameter group A1 and A2 showed unsatisfactory growth performance in the first year,while all the 3 diameter groups in the second year had better growth performance than plants with top-remaining treatment in terms of height,diameter,crown width and biomass.
