本文应用生长分析法，系统研究了食用百合干物质积累、分配、运转的规律。结果表明干物质积累是“Ｓ”型曲线，ｙ＝９９．３５ｅ０．０２２４Ｘｒ＝０．９６６９。干物质分配中心有３个：即枞形前为茎叶；枞形到开花为茎、叶与鳞茎；开花后为鳞茎。两年生百合单株茎叶贮存性物质运转量为２．３～４．２ｇ，相当于鳞茎重的８．９％～１６．１％。并提出了不同产量水平干物质积累模式，可在生产中监测群体发展动态，预测产量和采取相应调控措施。 In this paper, the law of dry matter accumulation, distribution and operation of Edible Lily was systematically studied by using the method of growth analysis. The results showed that dry matter accumulation was “S” curve with y = 99.35e0.0224Xr = 0.9669. There are three dry matter distribution centers: the fronds are stems and fronds; fronds are flowering stems, leaves and bulbs; blooms are bulbs. Bili per plant stem leaf storage material operation capacity of 2.3 ~ 4.2g, equivalent to bulb weight of 8.9% to 16.1%. And put forward the pattern of dry matter accumulation at different production levels. It can monitor the development of population in production, forecast the yield and take corresponding control measures.
