| 摘 要： | 在临泽绿洲耕作层保水能力较差的新垦沙地进行了春玉米有限灌溉试验研究,结果表明,灌水最少的WT1处理在耗水量最少的情况下产量不会降低,反而比灌水多的WT2,WT3,WT4,WT5和CK产量要高,增幅分别为23.6%,15.6%,44.0%,16.5%和8.7%;在苗期和拔节期,处理WT1,WT2,WT3与WT4,WT5和CK之间叶面积指数存在显著性差异,尤其是WT1与CK之间显著性差异最大,WT1比CK叶面积分别降低21.4%,12.4%;在苗期、抽雄期、吐丝期、灌浆期,WT1比CK株高分别降低11.9%,15.2%,6.1%,7.8%;所有处理及CK在灌浆期间灌浆强度基本不存在显著性差异;处理WT1,WT2,WT3与WT4,WT5及CK之间千粒质量存在显著差异,尤以WT1与WT4间差异最显著,WT1比WT4增加26.9%。

| Abstract: | Experimental study was conducted in Linze oasis irrigation region which has poor water retention capacity.The result indicated that the highest grain yield was obtained in WT1 with the least water consuming and its grain yield increased by 23.6%,15.6%,44.0%,16.5% and 8.7% than those in WT2,WT3,WT4,WT5 and CK respectively.Significant differences were found among some treatments and CK at some stages,especially between CK and WT1.The LAI increased by 21.4% and 12.4% in CK than in WT1 at the seedling stage and... |
