【摘要】 樟子松(Pinus sylvestris var.mongolica)是内蒙古自治区中西部人工造林的主要树种之一,在物种保存、科学研究、生态和经济效益等方面,都具备研究和保护的价值。本研究以la生樟子松菌根苗和轻基质营养袋苗为研究对象,在不同栽植环境下对这两种樟子松幼苗的生长情况进行了研究,并得出了以下结论:1.智能温室中理想的生长环境能较大程度提高两种樟子松幼苗的成活率、生长量及苗木生物量。2.在智能温室和露天空地中樟子松菌根苗优于轻基质营养袋苗,其移栽成活率、生长量及苗木生物量大;在太阳能电池板下,移栽成活率表现为樟子松菌根苗优于轻基质营养袋苗,但生长量及苗木生物量表现为樟子松轻基质营养袋苗优于菌根苗。3.在相同的生长环境下,樟子松菌根苗比樟子松轻基质营养袋苗对环境适应性更强。更多还原

【Abstract】 Pinus sylvestris var.mongolica is one of the main tree species in Midwest of the Inner Mongolia Autonomous Region plantation,in terms of species conservation,scientific research,ecological and economic benefits,have research value and protection-In this study,la of Pinus sylvestris var.mongolica mycorrhizal and light matrix nutrition bag seedlings as the research object,made study on the growth of different planting environment of these two kinds of Pinus sylvestris var.mongolica seedlings,and reached the following conclusions:1.Intelligent greenhouse can provide an ideal growing environment for improving largely survival rate,growth and seedling biomass of the two kinds of Pinus sylvestris var.mongolica.2.Pinus sylvestris var.mongolica mycorrhizal.seedlings are superior to the light matrix nutrition bag seedlings in the intelligent greenhouses and open space,where transplanting survival rate,growth and large biomass of seedlings are higher.Under solar panels light,the transplanting survival rate shows that the Pinus sylvestris var.mongolica mycorrhizal seedlings are superior to the light matrix nutrition bag seedlings,but the growth capacity and seedling biomass are light matrix nutrition bag seedlings are superior to the light matrix nutrition bag seedlings.3.In the same growth environment,the environmental adaptability of Pinus sylvestris var.mongolica seedlings is better environmental adaptability than the light matrix nutrition bag seedlings.更多还原
