摘　　要： 以人工红松Pinus koraiensis幼林为研究对象,进行5种省力化育林方式(单层遮阳网覆盖、双层遮阳网覆盖、黑色地膜覆盖、白色地膜覆盖、喷洒化学试剂)的试验并与无处理对照区进行比较,研究省力化育林措施对幼林生长和抑制杂草的效果。结果表明:省力化育林措施在促进幼林生长和抑制杂草生长上具有明显效果,当年幼苗苗高分别提升15%、39%、28%、7%和24%,地径分别提升9%、31%、19%、6%和16%,保存率分别提升5%、17%、12%、3%和11%,总生物量分别提升15%、39%、26%、7%和18%,控草效果分别提升52%、90%、36%、27%和67%;翌年幼苗苗高分别提升18%、42%、20%、10%和26%,地径分别提升17%、42%、20%、9%和26%,保存率分别提升5%、17%、12%、3%和10%,总生物量分别提升15%、39%、27%、7%和18%。 Taking artificial Pinus koraiensis young forest as the research object, the tests of five labor-saving cultivation ways （single sun-shade net cover, double sun-shade net cover, black plastic mulching, white plastic mulching, spraying chemical reagents） were compared with no treatment control area to study labor-saving cultivation measures and weed suppression effect difference for the growth of young forest. Experimental results show that labor-saving cultivation measures to promote young forest growth and inhibit the growth of weeds has significant effect, the seedling height promote 15%, 39%, 28%, 7% and 24%; Ground diameter promote 9%, 31%, 19%, 6% and 16%; Survival rate promote 5%, 17%, 12%, 3% and 11%; Total biomass promote 15%, 39%, 26%, 7% and 18%; Accused of grass effect promote 52%, 90%, 36%, 27% and 67% at first age. The following seedling height promote 18%, 42%, 20%, 10% and 26%; Ground diameter promote 17%, 42%, 20%, 9% and 26%; Survival rate promote 5%, 17%, 12%, 3% and 10%; total biomass promote 15%, 39%, 27%, 7% and 18% at second age.
