以1990—2004年湖北省中稻区域试验汇总资料及武汉、荆州、襄阳气象站的气象要素测报资料为依据,分析了各气象要素与杂交中籼稻年度间产量的相关性。结果表明,各气象要素均对杂交中籼稻产量产生了不同程度的影响,从气象要素与杂交中籼稻产量的相关性分析结果可以看出,高产年份要求杂交中籼稻在生殖期间日平均日照时间不少于6.4 h,日平均蒸发量不低于5.5 mm,日平均地温在30.0~32.5℃,日平均气温在27.0~28.3℃,日平均昼夜温差大于7.5℃,日平均空气相对湿度在70%~80%,累计降雨量应在100~220 mm范围内。高产年份必须是各种气象要素都处在适宜范围的最佳组合,若一项或多项气象要素指标没有达到上述适宜范围就会导致低产或中产。
Based on the data of the regional experiment of middle rice in 1990-2004 in Hubei Province and the meteorological elements of Wuhan, Jingzhou and Xiangyang meteorological stations, the correlation between each meteorological element and the annual yield of indica hybrid rice was analyzed. The results showed that all the meteorological elements affected the yield of hybrid mid-season indica rice to varying degrees. According to the correlation analysis between the meteorological elements and the yield of mid-indica hybrid rice, the average daily sunshine time of indica hybrid rice during the high-yielding year The average daily temperature is 30.0 ~ 32.5 ℃, the daily average temperature is 27.0 ~ 28.3 ℃, the average daily temperature difference is more than 7.5 ℃, the average daily relative humidity is between 70% ~ 80%, the cumulative rainfall should be in the range of 100 ~ 220 mm. High-yielding years must be the best combination of meteorological elements in the right range, with one or more of the meteorological elements failing to reach the above-mentioned ranges, resulting in low or medium yields.
