Effects of Different Irrigation Treatments on Maize Water Consumption, Growth and Yield under Film Hole Irrigation

Abstract:

Through film hole irrigation test-pit experiments,the effects of different irrigation treatments on water consumption,growth characteristics and maize yield were studied.The result showed that the jointing stage and heading stage were the key stages of water requirement of maize.Water consumption increased with the increased irrigation quota at the same number of irrigation.Effect of irrigation treatment on maize biological index was significant in less irrigation times and less irrigation quota.Water production efficiency increased 23.3% and yield increased 15.9% under film hole irrigation than that of border irrigation.Water consumption of the maximum yield was 3410m³/hm² under film hole irrigation.
