根据姜黄器官生长的变化特点，可将姜黄个体发育过程划分为３个时期。姜黄一生形成１３０叶，以苗期形成叶最多，共形成８０叶。叶面积在苗期较小，至９月下旬达最大值３３０２９ｃｍ２／株，叶面积指数（ＬＡＩ）４９５。净同化率（ＮＡＲ）在根状茎充实期最高３５４ｇ／ｍ２·ｄ。在苗期，干物质主要分配到叶部；在根状茎充实期，干物质主要分配到子姜。姜黄一生中发生２次生长中心的转移；当子姜生长率（ＣＧＲｒ）与叶生长率（ＣＧＲｔ）曲线相交时，可作为生长中心由叶向子姜转移的依据。
According to the characteristics of the growth of turmeric organs, turmeric individual development process can be divided into three periods. Turmeric formed 13 0 leaves, the formation of leaves at seedling stage up to a total of 8 0 leaves. Leaf area in the seedling stage is small, until late September up to a maximum of 3302 9cm2 / strain, leaf area index (LAI) 4 95. The net assimilation rate (NAR) was 3.54 g / m 2 · d at rhizome filling stage. At the seedling stage, the dry matter was mainly distributed in the leaves; in the rhizome filling stage, the dry matter was mainly distributed in the Ginger. Turmeric metastasis occurred in two growth centers during the lifetime of the turfgrass. When the CGRr and the CGRt curve intersected, it could be used as the basis for the growth center to be transferred from the leaves of Grifola frondosa.
