摘要
掌握适宜土壤水分,做到既节水又高产,是玉米非饱和灌溉技术关键。由桶测试验表明:控制土壤水分为田间持水量的70%,当灌溉水量为4 680 m3/hm2时,为玉米的最佳非饱和灌溉水量。
Key technology of unsaturated irrigatiml is to control suitable soil moisture and achieve both water saving and high yield. The bucket test showed that control soil moisture accounts for 70% of field capacity, the best corn unsaturated irrigation water was 4 680 m^3/hm^2.
