秋来斯红树莓在山西地区的引种试验初探

Preliminary Study on the Introduction Experiment of Red Raspberry Varieties Qiulaisi in Shanxi Region

2017年至2020年,在山西地区选取3个地点,对从辽宁地区引进的秋来斯红树莓品种进行区域试验,并与3个本地树莓品种进行对比。结果表明,秋来斯红树莓在山西地区于4月上旬萌芽,7月上旬开始开花,8月上旬果实开始成熟,采果期较其他品种长。定植第2年,秋来斯红树莓的株高最大,平均值为170 cm,且生长情况较好。经测定,秋来斯红树莓的平均单果重和聚合果数量均大于其他品种,营养物质含量也均高于其他品种。2017年至2020年,秋来斯红树莓的年产量均高于其他3个树莓品种,且年产量呈逐年增长的趋势。

From 2017 to 2020,3 locations in the Shanxi region were selected to conduct regional trials on the introduced red raspberry varieties Qiulaisi from Liaoning,and compared with 3 local raspberry varieties.The results showed that the red raspberry varieties Qiulaisi sprouted in early April in Shanxi region,bloomed in early July and matured in early August.The fruit picking period was longer than other varieties.In the second year of planting,the height of the red raspberry varieties Qiulaisi was the highest with an average of 170 cm,and its growth was better.According to measurements,the average single fruit weight and number of aggregated fruits of the red raspberry varieties Qiulaisi were higher than those of other varieties,and the nutrient content was also higher than other varieties.From 2017 to 2020,the annual production of the red raspberry varieties Qiulaisi was higher than that of the other 3 raspberry varieties,and the annual production showed a trend of increasing year by year.
