早稻后期的水浆管理是生产上有争论的问题之一。为了明确两熟制早稻广陆矮4号后期水浆管理对产量的影响,设置了后期灌深水、间歇灌溉和一灌到底三种方式比较试验,以探索后期合理的灌溉技术。三种方式是: (1)后期灌深水:前期深水护苗,浅水发棵,中期(5月30日到6月12日)烤田,齐穗后灌深水2.5～3寸,收割前5天排干。 (2)后期干干湿湿:前期和中期与(1)相同,齐穗后间歇灌溉,田面干干湿湿。
Late rice water slurry management is one of the controversial issues in production. In order to clarify the effect of late-stage watering and paddy management on the yield of early maturing rice in Guanglu Dazao of early maturing stage, a comparative experiment was set up for the later period of deep-irrigation, intermittent irrigation and one-irrigation in the end to explore reasonable irrigation techniques in the later stage. Three ways are: (1) late irrigation deep water: the early deep-water nursing, shallow water trees, mid-term (May 30 to June 12) grilled fields, full heading irrigation deep water 2.5 to 3 inches, 5 days before harvest Drain. (2) Drying and drying at the later stage: In the early stage and in the middle stage, same as (1), intermittent irrigation after heading stage and wet and dry field.
