共和盆地营造柽柳林因沙技术的研究

Research on Tamarix chinensis Afforestation for Dune in Gonghe Basin

选择多雨年份突击造林,对造林的成功具有重要意义。柽柳是(Tamarixchinensis)荒漠化治理中的先锋植物之一,既耐生理干旱,也耐大气干旱,具有极强的抗干旱能力,在沙地栽植后立即平茬复壮,可提高成活率,沙丘背风坡和丘间地是柽柳生长最好的地段,在降水250mm的共和盆地半干旱沙地均可栽植柽柳,几年后可形成柽柳群丛,恢复植被,达到控制流沙,固定沙丘的作用。

It is considered by afforestation for dunes fixation,that it’s very importance to rush silviculture during rainy days.Tamarix chinensis is one of the pioneer plant on afforestation for dunes fixation.It is either resistance physiological drought,or resistance atmospheric drought.The most suitable growing site for T.chinensis is more situated at the lee of dunes and interdune area.All of the placelike Gonghe Basin which it's principitation is about 250mm,Association of them will be formed after several years,so the shifting sand will be controlled,the migratory dunes will be fixed gradually.
