芹峰淮山栽培密度试验

Experiments on Cultivation Density of Dioscorea Opposita Thunb Variety Qinfeng

以淮山品种芹峰淮山为试验材料,设置行数单行垄植、双行垄植2个水平,株距8、16、24 cm 3个水平,进行两因素随机区组试验,探讨该品种的最佳栽培密度组合。结果表明:本试验条件下,单行垄植、株距8 cm组合条件下,即种植密度82 500株·hm^(-2),既可获得高产,又可取得较高的单株块茎重。

Taking Qinfeng, a Dioscorea Opposita Thunb variety, as the experimental material, single and double row cultivation were set up, and the plant spacing were 8 cm, 16 cm and 24 cm. Two-factor random block experiment was conducted to explore the best combination of cultivation density. The results showed that under the condition of single row cultivation and 8cm plant spacing, 82 500 plants per hectare could not only obtain high yield, but also obtain high tuber weight per plant.
