景电灌区农耕地枸杞引种试验研究

Introduction of Lycium barbarum Cultivars to Jingdian Irrigated Farmland

从宁夏、内蒙引进10个枸杞品种,在甘肃省景电灌区农耕地上开展了品种栽培对比试验。采用单因素多重比较(LSD)法、合理-满意度和多维价值理论的并合规则,对各品种幼树在生长量、产量、果实品质和抗逆性4方面进行量化比较和评价筛选。结果表明:0901、宁杞7号、宁杞5号、宁杞4号、宁杞3号均表现出适应性强、生长快、抗性强、丰产、果粒大、圆果型等特性,其中0901、宁杞7号、宁杞5号为早熟品种,宁杞7号、0901、宁杞4号的甜菜碱、类胡萝卜素及16种氨基酸含量较高,这5个品种适宜在景电灌区乃至甘肃枸杞人工栽培区农耕地上大力推广,0901为最佳品种;扁果枸杞表现出树势中庸、抗性强、果粒大、长扁果型、果粒外观品质佳、多糖及还原型维C含量高等特性,适宜作为辅助品种适当发展。

Ten cultivars of Lycium barbarum from Ningxia and Inner Mongolia were introduced to Jingdian irrigated farmland in Gansu,China.By using single factor multiple comparison（LSD） method and the combination rules of reasonable-satisfaction and multidimensional value theory,the introduced cultivars were compared and screened from the aspects of growth characteristics,yield,fruit quality and stress resistance.The results showed that 5 cultivars,such as 0901,Ningqi No.7,Ningqi No.5,Ningqi No.4,Ningqi No.3 all demonstrated strong adaptability,fast growth,strong resistance,high yield,big fruit grain,and round fruit type.Cultivar 0901,Ningqi No.7,Ningqi No.5 were early-mature varieties.High contents of betaine,carotenoids and 16 amino acids were found in cultivar Ningqi No.7,0901,and Ningqi No.4.All 5 cultivars could be popularized in the test area,in which cultivar 0901 was the best variety.Bianguogouqi showed middle vigor of growth,strong resistance,big and long flat fruit grain,better appearance quality of fruit grain,higher content of polysaccharide and vitamin C,it could be considered as auxiliary variety to be popularized.
