摘要
[目的]探明江苏省高砂土地区及相近生态条件下洋葱的栽培技术。[方法]采用随机区组排列,设计8种栽培密度、6个施肥水平,研究不同密度和施肥量对洋葱产量及主要农艺性状的影响。[结果]密度和施肥量对紫阳洋葱产量、株高、假茎粗、一级鳞茎率有显著影响。[结论]紫阳洋葱在江苏省高砂土地区适宜种植密度为41万~47万穴/hm^(2);施硫基高钾复合肥(N∶P2O5∶K2O=17∶6∶25)1350.0~1575.0 kg/hm^(2)。
[Objective]To explore the cultivation techniques of onion in high sand area and similar ecological conditions in Jiangsu Province.[Method]Eight planting densities and six fertilization levels were designed to study the effects of different densities and fertilization rates on onion yield and main agronomic traits.[Result]The density and fertilization rate had significant effects on the yield,plant height,pseudostem diameter and first-class bulb rate of Ziyang onion.[Conclusion]The suitable planting density of Ziyang onion in high sandy soil area of Jiangsu Province is 410000-470000 holes/hm^(2),and the application of sulfur based high potassium compound fertilizer(N∶P2O5∶K2O=17∶6∶25)was 1350.0-1575.0 kg/hm^(2).
