Abstract: 【Objective】 To study the changes of dry matter accumulation and crude starch and crude protein content in edible lily of Lanzhou in different ecological regions and to explore the regional differences. 【Method】 The growth analysis method was used to detect the accumulation of dry matter and the changes of crude starch and crude protein content in lily bulbs. 【Results】 The cumulative growth of dry matter of lily bulbs in different growth years of Yongjing County (YJ), Weiyuan County (WY) and Lintao County ( LT) planting areas was different. Compared with the three planting areas, the differences in dry matter accumulation of lily bulbs reached extremely significant levels (P<0.01). The cumulative amount of dry matter of Lanzhou edible lily bulbs in triennial was: LT>WY>YJ. The crude starch content LT of lily bulb was higher than those of YJ (24.74%) and WY (68.02%). The order of crude starch content was: LT>YJ>WY; the crude protein content LT of lily bulb was higher than those of YJ (8.55%) and WY (11.09%), the order of crude protein content was: LT>YJ>WY. The triennial Lanzhou edible lily, the dry matter accumulation of the WY and LT eco-regions was significantly positively correlated with the crude protein content (0.99^**, 1.00^**, P<0.01). 【Conclusion】 The nutrient content of edible lily in different planting areas was different, and the difference between areas was significant.
