云南水稻气候敏感性和栽培适应性

分析了低纬高原水稻生长独有的气候特点，将云南省不同地区的水稻产量与水稻生育期气象条件进行积分回归数植模拟分析，得出各地水稻气候敏感性综合数学表达式，区域划分指标以及空间分布规律。同时分析影响云南水稻产量的主要气候敏感因子和关键气候敏感期，并讨论了适应当地气候特点的水稻栽培要点。

STUDY ON CLIMATIC SENSITIVITY AND GROWTH ADAPTABILITY OF PADY RICE IN YUNNAN

This paper presents the climatic characteristics of paddy rice growth over theIow-latitude plateau of Yunnan,Integration-regression numerical modelling analysis of theyield and meteorology during the growth for various parts of the province gives integrativemathematic expressions for the growing rice sensitivity to the climate,indices of regionaliza-tion and space distribution characteristics for the different sections,together with the studyof major climate sensitivity factors with the critical period.On this basis,the rice-plantingschemes are presented for the different climates of the province.
