矮沙冬青引种栽培试验研究

Experiments on Introduction and CuIture of Ammopiptanthus nanus

从矮沙冬青在民勤地区引种栽培的苗期表现看出，矮沙冬青在生长和发育诸方面都表现出对引种地民勤干旱荒漠气候的较强适应能力，对各种灾害性因子也有很强的抵御力；种植在保水性好的沙壤土上，不仅利于保苗，也有利于苗木的生长；播种前种子需用浓硫酸腐蚀处理３０分钟，合适的播种覆土厚度为２－３ｃｍ。

mmopiptanthus nanus showed a stronger adaptive capacity in growth and development etc to Minqin desert climate,in addition to stron-ger resistivity to various disastrous factors.It suits to plant in sandy loam with better water-holding capacity, this is not only good for preser-ing seedling but also helps to seedling growth. Its seeds should be treated for 30 minutes by concentrated H_2SO_4 prior to sowing suitable soil-coyer-ing thickness ranges from 2-3cm.
