盐碱地种植耐盐植物经济效益分析

Analysis of Economical Efficacy of Planting Halophytes in Salt-affected Soils

在盐碱地上人工区域化种植翅碱蓬、柽柳、芦苇、甘草4种耐盐植物,根据植物生长习性不同选择不同的种植方式,翅碱蓬和甘草使用种子繁殖,柽柳采用扦插繁殖,芦苇采用地下茎切段繁殖,通过2～3a的种植,计算其生物产量和经济效益。结果表明:4种耐盐植物都具有较高的效益,其中翅碱蓬的效益最大,1hm^2可获得12万元左右的经济收益,证明在盐碱地上种植耐盐植物前景广阔。

Four Halophytes(Suaeda heteroptera Kitagawa,Tamarix chinensis Lour.,Phragmitas australis(Cav.)Trin ex Stend,Glycyrrhiza uralensis Fisch.)were planted in Salt-affected Soils.Choose different plangting way(Planting Suaeda heteroptera Kitagawa and Glycyrrhiza uralensis Fisch.by sowing seeds,planting Tamarix chinensis Lour,in branches of tree,Planting Phragmitas australis(Cav.)Trin ex Stend.in stems under land)based on grow temperament.Analyzed their output and economical efficacy after two-three years.Economical efficacy of these Halophytes was very high.The highest was Suaeda heteroptera Kitagawa,its economical efficacy was$120 000/hm^2 in one year.Planting Halophytes in salt-affected soils hade wide vista.
