赤峰市西部沙樱育苗技术及栽培表现

Cultivating techniquesand growth performance of western sand cherry seedlings in Chifeng city

西部沙樱(Prunus pumila var.besseyi)是原产于美国的阳性旱生灌木。自2008年引入赤峰市以来,西部沙樱在科尔沁沙地治沙造林中表现较好。然而,在观赏灌木培育中,常出现大量枯死枝夹杂在新萌生枝条中的现象,因此不宜用于园林绿化。首次发现3种害虫危害西部沙樱,其中黄褐天幕毛虫(Malacosoma neustria testacea)和苹毛丽金龟(Proagopertha lucidula)取食叶片,白星花金龟(Protaetia brevitarsis)取食果实。文章介绍了赤峰市西部沙樱育苗技术和栽培表现,提出了防控虫害建议。

Western sand cherry （Prunus purnila var. besseyi） is a shrub species originating in North America. In 2008, the shrubs were introduced into Chifeng City and grow well in Horqin sandy land as afforestation species. However, the shrubs of- ten had many dead branches among new ones that were not suit for landscaping. To our knowledge, three pest insects of the shrubs were first found that included Tent caterpillar （Malacosoma neustria testacea） and Proagopertha lucidula eating their leaves and White--spotted flower chafer beetle （Protaetia brevitarsis） eating their fruits. The cultivating seedling techniques and growth performance of the shrubs in the city Chifeng were described and some advice was given on the measures that should be taken to control the three new pest insects.
