摘　　要：以湿地芦苇生产区为研究背景,基于数理统计方法讨论了不同灌溉模式对芦苇主要生理指标:株高、茎粗、单位面积株数、产量的影响。研究发现苇田的干湿程度是影响芦苇生长的重要指标,晒田程度对芦苇株高、单位面积株数、产量影响显著,但对芦苇的茎粗影响不显著,苇田采用水层深20cm,自然落干后晒田5d,补水至20cm的浅、湿、干灌溉模式比较理想。Taking the reed production areas in wetland as research background, the influences of different irrigation modes on the main physiological indexes, including the plant height, the stem diameter, the yield and the number of plant in unit area, are discussed on the basis of the mathematical statistic theory. The results indicate that soil moisture is an important index influencing the growth of reed; the field drying degree has significant effect on the plant height, the yield of r.eed and the number of plant in unit area, but influence on the stem diameter is not significant. The shallow-wet-dry irrigation mode, in which the water depth is 20 cm originally, then the field sunsfor 5 days after naturally and then the water depth is supplemented to 20 cm, is suitable for the growth of reed.
