摘  要：
为探明不同灌水量对玉米生长动态与子粒灌浆特征的影响,研究分析了不同灌水量下绿洲春玉米不同生育期株高、干物质积累和干物质生产率变化动态及子粒灌浆特征。结果表明,不同灌水处理玉米株高均随生长而增加,但其生长速度有所不同,进入灌浆期玉米株高增加明显减慢,且随灌水量的增加而增加。合理有效的限量灌水不仅有利于玉米干物质积累并保持较高的干物质生产率,而且玉米籽粒平均灌浆时间相对缩短,平均灌浆速率相应增加。

摘  要：
In order to investigate the effect of different irrigation amounts on crop growth and grain filling characteristics of spring maize,an experiment was conducted to analyze the plant height,dry matter accumulation and dry matter production rate dynamics as well as grain filling characteristics performance of spring maize in oasis field under different irrigation amounts. The results showed that the plant height was increased with maize growth under different irrigation regimes,but their growth rates were quite different. The plant height increase slowed down obviously during grain filling stage,and increased with the increase of irrigation amount. The high dry matter accumulation and production rates were maintained under reasonable and efficient limited irrigation. The average grain filling duration was relatively shortened in maize under different irrigation amounts,but the average filling rates were improved correspondingly.
