摘要
为了选择适于甘肃省中部的临夏州地区所需要的防风固沙、盐碱地改良的优质灌木树种,2013年开展了四翅滨藜引种造林试验。在引种区测定四翅滨藜的物候期、生物量,并与当地乡土树种进行引种成活率比较。试验结果显示,引种四翅滨藜造林苗木4月8日进入萌芽期,4月20—28日进入展叶期,5月18日进入开花始期,6月15日进入末花期,6月20日进入营养生长高峰期,10月中旬进入休眠期;引种造林的四翅滨藜当年苗木的根、枝、叶生物量分别为56.54g、251.90g、177.14g,单株的生物量最大达758.2g。研究表明:引种的四翅滨藜与乡土树种相比具有较强的适应性,表现出较高的造林成活率及较大的苗木生长量,适宜在甘肃省中部的临夏州地区推广应用。
In 2013,an experiment on introduction and forestation is conducted to choose good and suitable shrub species required for wind-break and sand-fixation and saline-alkali soil improvement in Linxia region of middle areas of Gansu.The introduction viability is compared with the native tree species to measure phenological phase and biomasses of Atriplex Canescens in the introduction areas.Forestation seedlings of introduction Atriplex Canescens enter germination stage from April 8th,leaf expansion stage from April20 th to 28 th,fist-flowering dates on May 18 th,last-flowering dates on June 15 th,vegetative growth peak stage from June 20 th,and dormant period from the middle of October.The biomasses of roots,branches and leaves of current forestation seedlings of introduction Atriplex Canescens are respectively 56.54 g,251.90 g and 177.14 g.The biggest individual biomasses is 758.2g.The result indicates that introduction Atriplex Canescens has a stronger adaption compared with native tree species,and shows a higher introduction viability and bigger seedling growth,which is proper to be popularized and applied in Linxia region of middle areas of Gansu.
