适宜平凉幼龄果园间作的马铃薯品种筛选

Selection of Potato Cultivars Suitable for Young Orchard Intercropping in Pingliang City

为了改善平凉地区马铃薯品种结构,实现马铃薯早、中、晚熟品种合理搭配,筛选出适宜平凉地区幼龄果园间作的马铃薯新品种,2018年在平凉市庄浪县进行了适宜幼龄果园间作的马铃薯品种筛选试验。结果表明:早熟品种中,LK99和冀张薯12号,产量高,商品性好,且LK99生育期最短,仅为91d,能提早上市,可在当地幼龄果园中大面积推广种植。中晚熟品种中,中薯19号、陇薯12号、L08104-12产量高,商品性好,经济性状优良,综合表现好于当地主栽品种庄薯3号,适宜在庄浪县区域内种植。试验筛选出了早熟品种LK99和冀张薯12号、中熟品种中薯19号、晚熟品种陇薯12号和L08104-12,为实现当地马铃薯的早、中、晚熟合理搭配提供了依据。

In order to improve the local potato cultivar structure,make sure that the potato cultivars with early,medium and late ripening are combined reasonably,and screen out new potato cultivars suitable for young orchard intercropping in Pingliang area,the selection test was conducted in Zhuanglang county,Pingliang city in 2018.The results showed that’LK99’and’Jizhang No.12’had high yield and good commodity quality,’LK99’had the shortest growth period of 91 days,it could be earlier for market with good economic benefits,which could be widely cultivated.Among the cultivars of medium and late ripening,’Zhongshu No.19’’Longshu No.12’and’L08104-12’had high yield,good commodity quality,excellent economic performance,and their comprehensive performances were better than the local main cultivar’Zhuangshu No.3’,which were suitable for planting in Zhuanglang county.The selecting of early maturing potato cultivar’LK99’and’Jizhang No.12’,medium maturing potato cultivar’Zhongshu No.19’and late maturing potato cultivar’Longshu No.12’and’L08104-12’provided a scientific basis for the reasonable combination of early,medium and late ripening of local potatoes.
