毛乌素沙地樟子松抗旱造林关键技术研究

Key Technologies of Drought-resistant Afforestation with Pinus sylvestris var.mongolica in Maowusu Sandland

以榆林沙区为试验研究区,应用抗旱造林配套技术,在不同立地类型上营造樟子松示范林,对其成效进行分析。研究了深栽、容器大苗、GGR粉灌根、覆膜抗旱措施对樟子松造林成活率、保存率、生长量的影响,提出毛乌素沙地樟子松造林的关键技术,解决了沙区樟子松造林成活率低的问题。

Key technologies of drought-resistant afforestation with Pinus sylvestris var.mongolica in Maowusu sandland were investigated.Impacts of different measures,such as deep planting,adopting container seedlings,watering root with GGR powder,film covering,on the survival and preserving rates,and growth were determinated.Key technologies with P.sylvestris var.mongolica was developed to solve the problems of low survival rate of afforestation with P.sylvestris var.mongolica in sand area.
