摘要
以灌水量、灌水次数、灌水时间为变量因素,通过测产测墒的方式,对盐池县玉米水肥一体化灌水规律进行试验研究。结果表明:沙质土壤、降水量为282.8 mm、灌水次数为10次的条件下,3 750 m^3/hm^2灌水量为当地最佳灌溉量;在同为3 000 m^3/hm^2灌水量的条件下,灌水12次为最佳灌溉次数;膜下滴灌为最佳灌溉方式。
Study on maize irrigation system of integration of water and fertilizer in Yanehi County was carried out in this pa- per with irrigation amount, irrigation frequency and irrigation time as variable factors. Results showed that under the condi- tion of 282.8 mm rainfall, 10 times irrigation, the most suitable irrigation amount was 3 750 m3/hm2. Under the irrigation amount of 3 000 m3/hm2, 12 times of irrigation was the best frequency. Drip irrigation beneath the film was the best planting mode.
