摘要
为了丰富秦皇岛地区的柽柳种质资源,从山东和新疆等地引种了12个种(品种),与普通中国柽柳进行了适生性比较,对其扦插成活率、第2年保存率、株高和地径进行测量,评价不同柽柳种(品种)在秦皇岛地区的适生性。结果表明:柽柳不同种(品种)间的苗木保存率差异显著,且中国柽柳系列(红叶柽柳、中柽1号、中柽3号、中柽4号、中柽5号、中国柽柳、松柏柽柳)和甘蒙柽柳的保存率较好,为80.55%~93.11%,显著高于甘肃柽柳(68.26%)、白花柽柳(33.01%)、刚毛柽柳(21.44%)、密花柽柳(0%)和短穗柽柳(0%)。白花柽柳、刚毛柽柳和密花柽柳越冬后地上部分死亡,需要重新萌发生长。进一步对柽柳保存率较高的9个种(品种)的成活率、株高和地径进行综合分析,得到柽柳不同种(品种)在秦皇岛地区的适生性顺序为:中国柽柳>中柽4号>中柽3号>甘蒙柽柳>中柽5号>中柽1号>松柏柽柳>红叶柽柳>白花柽柳。这为冀东滨海盐碱地区的柽柳引种提供了一定的理论依据。
Twelve species were introduced from Shandong and Xinjiang provinces to enrich Tamarix germplasm resources and provide more breeding plants for Qinhuangdao.Survival rate of cuttings,keeping rate in second year,height and basal diameter of these 9 Tamarix chinensis species were conducted to evaluate their suitability for Qinhuangdao.Results showed that there were significant differences in keeping rate in second year between 9 Tamarix chinensis species introduced from Shandong and Xinjiang.Keeping rate of Tamarix chinensis(Tamarix chinensis Red.,Tamarix chinensis 1,3,4,5,Tamarix spp.,80.55%~93.11%)and Tamarixaus tromongolica were higher than Tamarix gansuensis(68.26%),Tamarix androssowii(33.01%),Tamarix hispida(21.44%),Tamarixar ceuthoides(0%)and Tamarix laxa(0%).The stems of Tamarix gansuensis,Tamarix androssowii and Tamarix hispida died after overwintering,and they needed to germinate and grow again in next spring.Suitability for Qinhuangdao was analyzed from survival rate of cuttings,height and basal diameter of these 9 Tamarix chinensis species,namely Tamarix chinensis>Tamarix chinensis 4>Tamarix chinensis 3>Tamarix austromongolica>Tamarix chinensis 5>Tamarix chinensis 1>Tamarix spp.>Tamarix chinensis Red.>Tamarix androssowii.This provides a theoretical basis for the introduction of Tamarix in Heibei east coastal saline areas.
