祁连山东端北麓地区不同沙棘品种引种和适应性筛选

Introduction and Adaptive Screening of Different Sea-buckthorn in Eastern End and Northern Foot of Qilian Mountain Area

为了筛选出高产优质沙棘栽培品种,在祁连山东端北麓地区引进5个大果沙棘品种,研究了不同品种间栽植成活率、保存率、枝梢生长量、品质和产量差异。结果表明:不同品种中深秋红的栽植成活率、保存率、百果重、果柄长、维生素C、胡萝卜素、总黄酮含量和折合产量均最高,综合适应性最强,建议在祁连山东端北麓地区沙棘产业构建中优先发展,乌兰沙林的以上指标均次于深秋红,可作为候补品种。

In order to screen high yield and high quality sea-buckthorn cultivated varieties in eastern end and northern foot of Qilian Mountain area,the five big fruit sea-buckthorn varieties were introduced,the difference of survival rate,preservation rate,shoot growth amount,quality and yield among different varieties were studied.The result showed that the survival rate,preservation rate,hundred fruits weight,fruit stalk length,vitamin C,carotene,total flavone content and equivalent yield of autumn red were highest in all varieties,the comprehensive adaptability was first,which should be used in sea-buckthorn industry firstly in eastern end and northern foot of Qilian Mountain area,the above index of wulansalin was second,which should be used as alternative varieties.
