为筛选出贵州省习水县海拔1 300m左右地区适宜推广应用的马铃薯品种,指导大面积生产,2015年开展了马铃薯不同品种产量与经济性状分析试验,结果表明:宣薯2号、青薯9号、会-2、威芋5号等四个品种均能正常成熟,生育期98~106d;产量均比当地白花洋芋(CK)显著增产,增幅在12.3%~30.8%之间。单株结薯数最多的是宣薯2号达7.7个,单株薯重最高的是会-2达0.365kg,商品薯率最高的是青薯9号达89.3%。综合分析比较,会-2、威芋5号、青薯9号、宣薯2号这四个品种均适宜习水县海拔1 300m左右地区大面积生产上推广应用。
In order to screen out the suitable potato varieties for promotion and application in Xishui County, Guizhou Province, about 130m above sea level, the large-scale production was guided. In 2015, the yield and economic traits of different varieties of potato were tested. The results showed that: No.2, No.5 and so on. All the four cultivars could mature normally with the growth period of 98-106 days. The yield of the four varieties all increased significantly from 12.3% to 30.8% compared with that of the local white flower potato (CK). The highest number of tuber tuber per plant was 7.7 on Xuanshu 2, the highest on single potato was -2.36kg, and the highest on potato was 89.3% of that on No.9. Comprehensive analysis and comparison, will -2, Konjac 5, Qingshu 9, Xuan Shu 2 are suitable for these four varieties Xishui County elevation of about 1 300m large-scale production on the promotion and application.
