摘要
文章在分析气象因子与水稻生长发育关系基础上,充分考虑黑龙江省的气候形势、地域特征及耕作制度,利用1971～2000年的气象资料,计算黑龙江省稳定通过18℃的天数、≥10℃积温及稻田干燥度指数等。通过指标对比分析,提出黑龙江省水稻区划细划的初步结论,为黑龙江省充分利用气候资源、发展高产优质农业提供参考依据。
Based on analysis of relationship between climatic factors and rice development. The paper adequately considers climate condition, region characteristic and cultivation system in Heilongjiang Province. Meteorological data is used to calculate number of days that temperature is steadily over 18 centigrade, and temperature accumulation that temperature is over 10 centigrade or equal to 10 centigrade, and dry index of rice fields in 1971-2000, and so on, which is compared to determinate index, then it comes to a conclusion about rice region division which provides reference basis for using climate resource, obtaining agriculture of high yield and high quality in Heilongjiang Province.
