| 摘 要： | 采用田间试验与室内分析相结合的方法，对冀东地区冬小麦京冬8号晚播高产（8111．52kg／hm^2）水平下植株的生长动态进行了研究。结果表明：出苗后植株鲜重、干重不断增加，分别在开花后24d，成熟时达一生最大值。其中，植株鲜重以拔节至挑旗增长速度最快（占最大值的42．13％），干重以挑旗至开花增长速度最快（占最大值的36．73％）。开花后，子粒鲜重、干重开始逐渐增加，成熟时达最大值，期间，以开花后12-24d子粒鲜重、干重增长速度最快，分别占最大值的51．11％和50．48％；出苗至挑旗，植株干物质的分配以叶片、叶鞘为主；挑旗至开花后12d，植株干物质分配以茎秆为主；此后，干物质向子粒中的分配迅速增加，成熟时，植株积累的干物质主要贮存在籽粒、茎秆中，分别占植株总干物重的36．93％和36．86％。 |

| Abstract: | Combining field experiment with indoor analysis,the growth trend of plants of late sowed high-yield winter wheat(Jingdong 8,8 111.52 kg/hm2) was studied.The results showed that after seedling emergence,the fresh weight and dry weight of the plant continuously increased.They reached their maximum value after 24 d and at maturation time.The fresh weight of the plant increased fastest from jointing stage to flagging stage,reaching 42.13% of the maximum value,while the dry weight increased fastest from flagging... |
