我区是中外闻名的“西北黄花菜”主要产区,除社、队大面积栽培外,社员个人在房前屋后、田边地角、路旁山坡大量种植。黄花菜在本地表现耐早、耐寒,且具有个大、肉厚、色亮、质优等特点。每年的出口量占全国总出口数的14％以上。由于黄花菜主要靠种苗(俗称黄花根)分根繁殖(取自然蘖),1亩地需用种苗600—1,000斤,1亩老株大约能供6—8亩地的种苗,繁殖系数较低,远远不能满足种用和市场供应的需要。黄花菜也能用种子繁殖,但由于陇东无霜期短,结籽不易而少,其优良种性不易保持稳定。另外,还要经过收晒籽种、整地育苗、移栽定植等环节,比较麻烦,群众也很少采用。
My area is the famous “Northwest Daylily” main producing areas, in addition to community, team large-scale cultivation, members of the individual in front of the house, Tanabe corner, a large number of roadside hillsides. Lily early in the local performance of resistance, cold, and has a large, fleshy, bright color, high quality and so on. Annual exports account for more than 14% of the country’s total exports. Because lily mainly by seedlings (commonly known as rhizome) rooting (take natural tillering), 1 mu of land need to use 600-1,000 pounds of seedlings, 1 mu of old strains of about 6-8 acres of land for seedlings, breeding Coefficient lower, far from meeting the needs of species and market supply. Day lily can also be used for seed multiplication, but due to the short frost-free period in eastern Gansu, it is not easy to produce seeds and less, and its superiority is not easy to maintain its stability. In addition, but also through the sun-sun seed, soil preparation seedlings, transplanting and planting and other aspects of the more trouble, the masses rarely used.
