1976年是历史上温度较低的一年,全年生育期积温3348度(锦县),较1975年少331.8度,较常年少86.3度,日照吋数1343.9小时,较1975年少217.8小吋,较常年少33.6小时。如按今年生育期平均气温18.7℃折算,较1975年缩短生育日数17.7天,较常年缩短4.6天。特別是1976年的低温主要低在夏播作物生育期,因此对夏播作物的成熟是很不利的。
The year 1976 witnessed a historically low temperature. The accumulated annual temperature of 3348 degrees Centigrade (Jin County) during the year was 331.8 degrees less than in 1975, 86.3 degrees less than usual and the number of insoles was 1,343.9 hours, 217.7 inches less than in 1975. Perennial less 33.6 hours. For instance, according to the average temperature of 18.7 ℃ during the growth period of this year, it will be 17.7 days shorter than the number of birth days in 1975, 4.6 days shorter than that of the normal year. In particular, the low temperature in 1976 is mainly lower in summer sowing crop growth period, so the summer sowing of crops is very unfavorable.
