黄花菜(Hemerocallis citrina),又名金针菜,系百合科萱草属宿根多年生草本植物,是我国的特产蔬菜。黄花菜适应性强,耐旱耐瘠薄,既是优良的经济植物,又是理想的水土保持植物。 在通常情况下,黄花菜繁殖多采用营养繁殖,即分蘖(分蔸)、切片(切根)、短缩茎切割和花苔腋芽繁殖,近期也有采用组织培养繁殖的。种子繁殖通常采用种子点播育苗。营养繁殖的秧苗,虽能保持品种性状的稳定性,但繁殖系数低,大面积推广栽植受到限制;组织培养繁殖,对技术、设备条件要求高,在生产上有局限性;常规的种子点播育苗,土地利用率低,产苗量小,既浪费工时,又推迟栽植时间。黄花菜经济效益高,适宜栽培区域 Daylily (Hemerocallis citrina), also known as lily, lily Hemerocallis perennial perennial herb, is China’s specialty vegetables. Day lily adaptable, drought-resistant infertility, both good economic plants, but also the ideal soil and water conservation plants. Under normal circumstances, the use of reproductive lily nutrition reproduction, that is, tillering (division), slicing (cutting), shortening stem cuttings and flowers moss axillary buds, but also recently adopted tissue culture and reproduction. Seed breeding is usually seed-based seedling breeding. Although vegetatively propagated seedlings can maintain the stability of variety traits, the propagation coefficient is low and there is a limit to large-scale popularization and cultivation. Tissue culture and propagation require high technical and equipment conditions and have limitations in production. Conventional seed-based seedling nurseries , Low land utilization rate and small seedling production amount of waste of working hours and postpone planting time. Day lily high economic efficiency, suitable for cultivation area
