| 摘 要： | 三种不同技术措施对促进马尾松天然更新效果表明:各种人工促进措施对提高林地利用率、马尾松幼林密度和幼树生长均有明显效果。其中采用劈草、炼山、辅助播种的幼林,其密度比对照提高66％,且分布均匀,四年生幼树平均树高增长25％;平均地径增大23％,预计至主伐(40年)时,每公顷每年可增加经济收入383.2元。采取劈草、炼山措施其幼林密度、平均树高、平均地径分别提高34％、21.5％、13％。

| Abstract: | The study on the effect of three kinds of measures to promote natural regeneration shows that very kind of artificial measures can obviously increase the land's vtilization ratio ( the area ratio of advlt forest), density and growth of young growth. The density of young growth treated with herb-chopping, controlled burning and supplementary seeding increased by 66%, and presenting even distribution. The average height and diemeter at butt-end of 4-year-old cyoung growth increased by 25% and 23% respectively It is estimated that eco-nmic bemifet per year in the final cwtting phase ( 4C-year-old ) will grow 383.2 yuan per ha., Next, the density, average height, diameter at butt-end and economic benifet of young growth managed by herb-chopping and controlled burring can increase 34%, 21.5%, 13% respectively in the comparison with the control. |
