Study On Twelve Kinds Of Landscape Plant’s Drought Resistance

Garden plants is the most important part of the landscape.China’s freshwater resources per capita is limited. How to scientific develop urban landscape in arid,semi-arid area is very import. Coordinate urban garden plants and the water requirement conflicts become a important topic.This experiment selected twelve garden plants of Ordos area, including iris lacteal var.,Hylotelephium spectabile,Sedum aizoon L.,Ulmus pumila cv. Jinye is common garden plant in the Ordos;Ammopiptanthus mongolicus,Amygdalus mongoulica, Berberis caroli,Ampelopsis acnitifolia leaves is from the Ordos wild plants acclimatization garden plant; Monarda didyma, Lavandula dentate, Lavandula angustifolia, Lavandula dentate is a fragrant valuable garden plant which is introduced from abroad.The order of drought resistance is all from strong to weak.and The following conclusions are drawn from the experiment.:(1) 2 weeks later:Hylotelephium spectabile, Lavandula angustifolia, Lavandula dentate, lavandula latifolia, Iris lactea var., sedum aizoon, Ulmus pumila cv. Jinye, Ammopiptanthus mongolicus, Amygdalus mongoulica. Ampelopsis acnitifolia.Berberis caroli,Monarda didyma.4 weeks later:Hylotelephium spectabile,sedum aizoon,Iris lactea var.,Lavandula dentate.Ammopiptanthus mongolicus,Lavandula angustifolia,Ulmus pumila cv. Jinye,lavandula latifolia,Amygdalus mongoulica,Ampelopsis acnitifolia,Berberis caroli,Monarda didyma.6 weeks later:Hylotelephium spectabile,Iris lactea var.sedum aizoon,Ulmus pumila cv. Jinye,Lavandula angustifolia,lavandula latifolia.Lavandula dentate.Ampelopsis acnitifolia,Ammopiptanthus mongolicus,Amygdalus mongoulica,Berberis caroli,Monarda didyma.(2) 2 weeks later:Hylotelephium spectabile, sedum aizoon, Ammopiptanthus mongolicus, Iris lactea var.,Lavandula dentate, Lavandula angustifolia, lavandula latifolia, Ampelopsis acnitifolia, Berberis caroli, Amygdalus mongoulica, Ulmus pumila cv. Jinye, Monarda didyma.4 weeks later:Hylotelephium spectabile,sedum aizoon.Ammopiptanthus mongolicus.Lavandula angustifolia,Iris lactea var.,Berberis caroli, Ampelopsis acnitifolia,Ulmus pumila cv. Jinye,Amygdalus mongoulica,lavandula latifolia,Lavandula dentate,Monarda didyma.6 weeks later:Hylotelephium spectabile,sedum aizoon,Ammopiptanthus mongolicus,Iris lactea var.,Lavandula angustifolia,Amygdalus mongoulica.Ulmus pumila cv. Jinye.Others all die.(3) 2 weeks later:Hylotelephium spectabile.Iris lactea var.,sedum aizoon,Lavandula angustifolia,Ulmus pumila cv. Jinye,Ammopiptanthus mongolicus,lavandula latifolia.Lavandula dentate.Ampelopsis acnitifolia,Amygdalus mongoulica,Berberis caroli,Monarda didyma.4 weeks later:Hylotelephium spectabile, sedum aizoon, Lavandula angustifolia, Ammopiptanthus mongolicus,Iris lactea var., Amygdalus mongoulica, Ampelopsis acnitifolia,Berberis caroli,Monarda didyma,Ulmus pumila cv. Jinye,Lavandula dentate,lavandula latifolia.6 weeks later:Hylotelephium spectabile, sedum aizoon, Ammopiptanthus mongolicus,Iris lactea var.,Lavandula angustifolia,Monarda didyma. Others all die.(4) 2 weeks later,12 kinds of garden plant as a whole drought resistance rank: Hylotelephium spectabile,Iris lactea var.,sedum aizoon,Lavandula angustifolia,Lavandula dentate.Ammopiptanthus mongolicus.lavandula latifolia,Ampelopsis acnitifolia,Amygdalus mongoulica,Berberis caroli,Monarda didyma,Ulmus pumila cv. Jinye.(5) 4 weeks later,]2 kinds of garden plant as a whole drought resistance rank: Hylotelephium spectabile.sedum aizoon,Lavandula angustifolia,Ammopiptanthus mongolicus.Iris lactea var.,Amygdalus mongoulica.Ampelopsis acnitifolia,Ulmus pumila cv. Jinye,Berberis caroli,Lavandula dentate,lavandula latifolia,Monarda didyma.(6) 6 weeks later,12 kinds of garden plant as a whole drought resistance rank: Hylotelephium spectabile,sedum aizoon,Ammopiptanthus mongolicus,Iris lactea var.,Lavandula angustifolia,Ulmus pumila cv. Jinye,lavandula latifolia,Lavandula dentate,Ampelopsis acnitifolia,Amygdalus mongoulica,Berberis caroli,Monarda didyma.
