生态优新树种在宁夏地区引种栽培初探

Introduction and Cultivation of New Tree Species in Ningxia Region

随着美丽宁夏建设的不断推进,生态优新观花观果树种以其较强的观赏价值较受关注,市场需求量较大,但宁夏地区存在树种单一,森林经济价值低的问题。为此,于2018年春开始陆续引种了不同品种丝绵木和文冠果4个树种,通过物候期和生长适应性观测,结果表明:引种的4个树种均生长良好,能够在宁夏地区安全越冬和越夏,具有较强适应性,适宜在宁夏银川市环境因子差异不大的地区种植,能够丰富宁夏地区树种资源,此外,可以通过提高森林质量来提高森林的生物多样性和经济效益。

With the development of Ningxia's ecological construction,the tree species with strong ornamental values are drawing people's attention and winning increasing market demands.However,there are problems in single tree species and lower economic values of forests in Ningxia regions.Under such background,4 tree species have been introduced since 2018,including Euonymus bungeanus and Xanthoce sorbifolia Bunge.Their ornamental values were illustrated based on observations in phenological and growth periods,which is useful for their popularization and application in Ningxia regions.It was proposed that the improvement of forest quality could enhance biodiversity and economic benefits.
