| 摘 要： | 选择毕节地区主推品种威芋3号微型薯(大小为每粒11～20 g)开展不同种植密度对一级原种繁殖的影响试验。结果表明:在品种和粒级相同的情况下,原原种扩繁一级原种时晚疫病发生轻重与种植密度不相关;每667 m2种植密度从4 500粒增加至6 500粒,各处理间产量不存在显著差异性。综合单位成本、产量、大中薯比例等分析,在选择粒级为每粒11～20 g的原原种进行栽种时,每667 m2种植密度以4 500～5 500粒较适宜。

| Abstract: | The relationship between elite seed multiplication and planting density of minitubers(size range was 11-20 g) was studied in a field trial using cv.Weiyu 3 as plant material.The results showed that incidence of late blight was not correlated with planting density and there was no significant difference in yields of elite seed among planting densities of minituber from 4 500 to 6 500 hills on 667 m2 of land.Based on integrated analysis on cost,yield and tuber size distribution,the planting density of minitub... |
