| 摘 要： | 为了掌握制种玉米适宜灌水量，用不同灌水量处理，研究其生长状况及生理变化。结果表明：不同灌水量对玉米净同化率、干物质有明显影响，灌水多，净同化率大，干物质积累多；对叶面积、株高、产量的影响以灌水量为5250 m3/hm2的条件下叶面积大、株高生长快、高度最高，水分对产量的贡献率大，可获得较高产量。在干旱缺水地区玉米全生育期灌水量在5250 m3/hm2可作为当地适宜节水灌溉量。

Influence of Irrigation Quantity to Dry Matter Accumulation and Yield of Corn |
| |
| Abstract: | Growth status and physiological changes of corn were studied with different irrigation quantity in order to research suitable irrigation amount of seed corn. The results showed that: different irrigation quantity had obvious effect to net assimilation rate and dry treatment seed material of corn, net assimilation rate was big and dry matter accumulation was much because irrigation quantity is much. Leaf area was big, plant growth was fast, height was the highest and contribution rate of water on yield was big, higher yield could be obtained in the irrigation times 5250 m3/hm2 conditions. Irrigation water 5250 m3/hm2 of corn whole growth period can be used as appropriate amount of water saving irrigation quantity in water shortage. |
