Abstract: With two dif ferent cult ivat ion models, the accumulat ion and part ition of dry materials and function to g rains in fox tail millet are studied. The result s show ed that there are 3 periods for accumulat ion of dry materials in the w hole grow th period, slow ly increasing period, linear increas ing period and repeated slow ly increasing period during the grow ing period of foxtail millet . In dif ferent period, the distribut ion center of dry materials is various. In total dry materials, the accumu lat ion quant ity is about 55%~ 60% before blooming. T he cont ribut ion of photosynthesis product s to ear g rain w as about 8%~ 10% . During the later grow th period, dry w eight of vegetat ive organ rose ag ain. As for cult ivat ion models the total dry materials amount is affected. The total dry w eight of high yielding model is obviously higher than that of medium yielding model w ith large difference presenting in dry materials of leaf and ear w eight.
