摘要:

为了明确栽插方式对甘薯生长及产量的影响。以‘泰紫薯1号’和‘泰薯15’为试验材料,研究直栽、斜栽、平栽3种不同栽插方式对2种类型甘薯品种的茎叶生长、T/R值、块根膨大速率、产量及其构成因素、商品薯率的影响。研究结果表明,2个品种鲜薯产量和薯干产量均表现为平栽方式>斜栽方式>直栽方式;在斜栽和平栽方式下2个品种T/R值无显著差异,但显著低于直栽方式;2个品种甘薯块根膨大速率均表现为平栽方式>斜栽方式>直栽方式;平栽与斜栽方式2个品种块根商品薯率均高于直栽方式,平栽方式结薯数和薯块均匀度优于斜栽方式。综上所述,平栽和斜栽方式优于直栽方式,能够提高甘薯鲜薯产量及商品性,其中平栽方式较适用于鲜食型甘薯,淀粉型甘薯可根据种植条件选择适宜的栽插方式。

Abstract:

The aim was to clarify the effects of planting methods on the growth and yield of sweetpotato. ‘Taizishu No.1’and ‘Taishu 15’ were used as experimental materials to study the effects of straight, oblique and flat planting methods on the growth of stem and leaf, T/R value, the root expanding velocity, yield and its constituent factors, and marketing tuber ratio of the two types of sweetpotato varieties. The results showed that the fresh yield and dry yield of the storage root of the two varieties were shown as flag planting > oblique planting > straight planting. There was no significant difference in T/R value between the two varieties under oblique planting and flat planting, but it was significantly lower than that of straight planting. Among the different planting methods, the storage root expansion rate of sweetpotato of the two varieties was shown as flat planting > oblique planting > straight planting. The marketing tuber ratio of the two sweetpotato varieties under flat and oblique planting was higher than that of straight planting, and the root number per plant and the evenness of the sweetpotato roots under flat planting were better than those under oblique planting. In conclusion, flat planting and oblique planting were better than straight planting, which could improve the yield and marketability of fresh-edible sweetpotato. Flat planting was more suitable for fresh-edible sweetpotato, and the suitable planting method for starch sweet potato can be selected according to the planting conditions.
