修文县马铃薯新品种适宜垄作方式及密度探索

Study of Suitable Ridge Cultivation Methods and Density of New Potato Varieties in Xiuwen

为筛选出适宜修文县种植的马铃薯新品种及合理的种植规格,在小箐镇开展了费乌瑞它、青薯9号、威芋5号、黔芋8号的垄作方式及密度配置试验。结果表明,4个品种在产量、单株结薯数、单株薯重、单株小薯数上存在极显著或显著差异,同一品种在单垄单行或单垄双行垄作方式下,在行距相同而株距不同时产量表现亦存在区别。黔芋8号产量潜力和商品率均比较高且适应性较强,可以进行生产示范,且以单垄单行+行距60cm+株距28cm种植方式效果最好。

In order to screen out new potato varieties suitable for cultivation in Xiuwen County and reasonable planting specifications, a ridge cultivation method and density distribution test of Feiwuruita, Qingshu No.9, Weiyu No.5 and Qianyu No.8 were carried out in Xiaojing town. The results showed that there were significant or very significant differences in yield, number of potatoes per plant, weight of single potato, and number of small potatoes per plant, in the single ridge single row or single ridge double row ridge mode, the same variety has different yield performance when the row spacing is the same and the plant spacing is different. Qianyu No. 8 yield potential and commodity rate were relatively higher and adaptable stronger, in addition, the best planting method of Qianyu No.5 is to use single ridge single row + row spacing 60cm + plant spacing 28cm.
