中文摘要：

通过在2012年对滴灌春小麦的大田试验,研究了不同灌水次数对滴灌春小麦的生长和产量的影响。结果表明：多次灌水有利于小麦株高生长、叶面积系数增大,同时有利于小麦理论产量增加,灌水次数对中等定额灌溉处理春小麦生长影响最明显;在相同的灌溉定额条件下,增加灌水次数,有利于小麦增产,尤其对于中等定额灌溉处理时增加幅度相对较大,而对小及大定额灌溉处理产量的影响相对较小。

英文摘要：

The influence of different irrigation times on the growth and yield of spring wheat under drip irrigation was studied in northern Xinjiang in 2012.The results showed that several times irrigation was conducive to the growth of plant height,the increase of leaf area index and the theoretical yield of wheat;the influence of irrigation times on the growth of spring wheat under mediumscale irrigation quota was the most obvious.Under the same irrigation quota condition,the increase of irrigation times was conducive to the wheat yield.The increase rate was relatively high for the medium-scale irrigation quota,while the impact on the production of treatments under small and large scale irrigation quota was relatively small.
