中文摘要: 利用旬雨量与历史同期产量资料,使用积分回归和多元回归等方法,分析自然降雨量与水稻产量的关系,以证实人工增雨对水稻产量提高所起的作用。结果表明,全省早稻亩产量随旬雨量增加平均为0.164kg/mm,晚稻亩产量增加平均为0.11kg/mm。
Abstract:By use of the dekad rainfall and isochronal yield data,the relationship between natural rainfall and the rice yield was analysed by the integral regression and multiple regression equations. The results confirm that the increament of early rice yield and late rice yield by the artificial rain enhancement may by averaged to per mu 2. 46kg/mm. ha-1 and 1. 65kg/mm. ha-1,respectively.
