摘要
在新疆准噶尔盆地荒漠区进行了4个地理种源的梭梭植苗造林试验,结果表明:吐鲁番白梭梭和精河梭梭的苗木高、径生长要好于吐鲁番梭梭和奇台梭梭。由此初步确定吐鲁番白梭梭和精河梭梭是优良的表现型,可作为干旱区大面积营造防风固沙林的梭梭树林种源推广应用;而在造林中施用GGR生长调节剂处理苗木根系可以促进梭梭苗木的径生长。
Tree planting experiment of Haloxylon Bge of four provenances was conducted at Junggar Basin of Xinjiang Uygur Autonomous Region. The results showed the height and diameter growth of Turpan Haloxylon persicumand Jinghe Haloxylon ammodendron were better than that of Turpan Haloxylon ammodendron and Qitai Haloxylon ammodendron. It was preliminarily concluded that Turpan Haloxylon persicum and Jinghe Haloxylon ammodendron had superior performance, and could be used as the plant materials for windbreak and dunefixing forest construction at dry areas. The results also indicated that the growth of Haloxylon Bge plants could be promoted by treating the root system with plant growth regulator GGR.
