为了促进娜塔栎幼林的生长,开展了娜塔栎幼林地表覆盖试验。以娜塔栎4年生幼林为试验对象,研究了不同地表覆盖材料对娜塔栎幼林胸径生长、树高生长的影响。结果表明:地表覆盖地膜、锯木屑都能有效促进娜塔栎幼林林分的营养生长,胸径、树高的增长量均显著高于对照。考虑到人工、成本方面的因素,娜塔栎幼林地表覆盖建议使用黑色地膜。 In order to promote the growth of the young tree Nata coturnum, the ground cover experiment of the young tree Nata oak was carried out. Taking 4-year-old young nursery of Quercus nucifera as test object, the effects of different ground cover materials on the DBH growth and tree height growth of young Junta natans were studied. The results showed that the surface mulching and sawdust could effectively promote the vegetative growth of the young stand of Nata kwa. The DBH and height of tree stand were significantly higher than those of the control. Taking into account the artificial, cost-related factors, Nata oak young forest land cover recommends the use of black plastic film.
