Limited Irrigation System of Spring Maize in a Semi-Arid Area of Northeast China

Abstract:

Article Preview

To improve the spring maizes water use efficiency (WUE) in a semi-arid of northeast, the research of limited supplementary irrigation system was carried out. It turned out that the increased production effects in the same amount of irrigation during single irrigation stage, filling stage was best, tasseling stage was better, jointing stage was good in the precipitation conditions of experiment period. The yield effects were different in the same amount of irrigation during two stages of equivalent for irrigation. It was best in tasseling stage and filling stage. It was better in the jointing stage and filling stage. And it was good in the jointing stage and tasseling stage. The yield effects during three stages of equivalent for irrigation was next to the irrigation of tasseling stage and filling stage, It was better than the irrigation of jointing stage and filling stage. Irrigation quota was 675 m3hm-2, irrigation was in filling stage, the amount was 675 m3hm-2.Keyword: spring maize; limited supplementary irrigation; production; water consumption; water use efficiency.
