中文摘要: 对杂交籼稻旱育抛栽适期分析表明:3月下旬连续5天平均气温在86℃以上或4月上旬气温在80℃以上时,可作为该时段保温旱育秧适宜播期的起点温度;适宜抛栽期以日平均气温稳定通过16℃的保证率>80%为起点,考虑高产秧龄和安全齐穗因素,依当年天气预报、苗情和茬口确定。
Abstract:The favourate date for Raising Seedling and transplanting of Hybrid Rice is analyzed. It is showed that the temperature of start seeding date is above 86℃ of five day sequence mean temperature in the third dekad of March and is above 80℃ in the first dekad of April.The temperature of start transplanting date is that of the assurance rate is above 80% of mean daily temperature steadily passing through 16℃ with the consideration of high product rice age and the factor of secure blooming. It is ultimately determineded according to local weather forcasting,rice growing and the former crops harvesting.
