With the aim to improve the production of saffron, key technologies for high yield cultivation were developed. The influence of different factors including seed treatment modes, fertilizer composition, planting time, planting density and bulb size on saffron productivity and bulb yield were investigated. The results showed that higher yield in saffron production could be obtained in the condition of complete bulb with outside flakes but not unwanted side-buds, the appropriate fertilizer of N 450 kg ? Hm-2, P2O5 225 kg ? Hm-2 and K2O 225 kg ? Hm-2 and the big-size bulb planted in the density of 10 cm x 10 cm in late November and early December after fine management.%通过探索长三角地区西红花栽培的高产关键技术,更好地指导生产.试验研究了不同种球处理方式、不同肥料配比及栽种时间、种植密度和球茎大小等因素对西红花生产和球茎产量的影响.试验结果表明,最适种球处理方式为整球茎保留膜质鳞片并去除多余侧芽；肥料施用以N450 kg·hm-2,P2O5 225 kg·hm-2和K2O 225 kg·hm-2为宜；栽植选用大球茎,最适种植密度为10 cm×10 cm,最佳栽种时间为11月下旬至12月初,采用精细管理,可获得较高的球茎产量.
