摘　　要：利用在田间用设置温度计,定点定时观测的方法,研究了5cm、10cm水层及池田边的水温和气温变化对水稻生长发育的影响。分析了6月份水稻分蘖期浅水(5cm水层)灌溉有利于促进低节位分蘖的原因;指出孕穗期深水灌溉是防御障碍性冷害的重要措施。utilized thermometer to observe water and air temperature change on every certain time ,then studied the influence of the temperature of5cm?10cm water layers and side of field to rice.Analyze the reason that cause shallow(5cm water layer)irrigation improved low node tillering in June rice tillering stage.Moreover,deep water irrigation in booting stage is an important defensive countermeasure of cold harm.
