贺兰山东麓洪积扇区5种适生灌木对比试验研究OA
Comparative Experimental Study on Five Suitable Shrubs in Alluvial Sector at Eastern Foot of Helan Mountain
在干旱荒漠区实施生态修复,首要任务是筛选适应极端环境的植物种类.适宜树种的筛选和应用是贺兰山洪积扇区生态修复的关键.为解决贺兰山东麓洪积扇区生态修复中因植物选择不当导致造林成活率不高的问题,以蒙古扁桃、红花多枝柽柳、酸枣、霸王、杠柳5种灌木为试验材料,在贺兰山东麓永宁县井子泉、平罗县大水沟开展试验,通过统计成活率、生长量,筛选出贺兰山东麓洪积扇区适宜栽植的灌木树种,以期为该区域生态修复苗木选择提供实践依据.结果表明:①5种灌木2年生容器苗造林当年成活率从高到低依次为酸枣、红花多枝柽柳、霸王、杠柳、蒙古扁桃;新梢生长量从大到小依次为红花多枝柽柳、霸王、杠柳、酸枣、蒙古扁桃.②2024年,酸枣、霸王、蒙古扁桃、杠柳2年生容器苗在大水沟的成活率高于井子泉,红花多枝柽柳则相反,其中酸枣在大水沟成活率最高(90%),蒙古扁桃与杠柳在井子泉成活率最低(80.67%).因此,在贺兰山东麓永宁县井子泉、平罗县大水沟周边区域适宜采用客土栽植酸枣、红花多枝柽柳等2年生容器苗.
In the implementation of ecological restoration in arid and desert areas,the primary task is to select suitable plant species that can adapt to extreme environments.The selection and application of suitable tree species are the key to the ecological restoration in the alluvial sector of Helan Mountain.To address the problem of low survival rate of afforestation caused by improper plant selection in the ecological restoration of the alluvial sector of Helan Mountain,using five shrubs,namely Amygdalus mongolica(Maxim.)Ricker,Tamarix gallica,Ziziphus jujube var.Spinosa,Zygophyllum xanthoxylon,and Periploca sepium Bunge,as experimental materials,experiments were conducted in Jingziquan in Yongning County and Dashuigou in Pingluo County.Through observation and statistics of survival rate and growth volume,suitable shrub tree species for afforestation in the alluvial sector of Helan Mountain were selected,with the aim of providing practical basis for the selection of tree seedlings for ecological restoration in the alluvial sector at eastern foot of Helan Mountain.The results showed:① The survival rate of 2-year-old container seedlings of the five shrubs in the current year,from high to low,was:Ziziphus jujube var.Spinosa,Tamarix gallica,Zygophyllum xanthoxylon,Periploca sepium Bunge,Amygdalus mongolica(Maxim.)Ricker;the growth volume of new shoots,from high to low,was:Tamarix gallica,Zygophyllum xanthoxylon,Periploca sepium Bunge,Ziziphus jujube var.Spinosa,Amygdalus mongolica(Maxim.)Ricker.② In 2024,the survival rate of 2-year-old container seedlings of Ziziphus jujube var.Spinosa,Zygophyllum xanthoxylon,Amygdalus mongolica(Maxim.)Ricker,and Periploca sepium Bunge in Dashuigou was higher than that in Jingziquan,while Tamarix gallica was the opposite.Among them,the survival rate of Ziziphus jujube var.Spinosa was the highest(90%),and the survival rates of Amygdalus mongolica(Maxim.)Ricker and Periploca sepium Bunge were the lowest(80.67%).Therefore,in the surrounding areas of Jingziquan in Yongning County and Dashuigou in Pingluo County on the eastern foot of Helan Mountain,it is advisable to adopt soil transplantation to plant 2-year-old container seedlings of Ziziphus jujube var.Spinosa,Tamarix gallica,etc.
