范县水稻种植气候适宜性分析

Analysis on climate suitability of rice planting in Fanxian

本文根据河南范县2013—2023年气候观测资料,对研究区近11年来的气候条件进行分析,从温度、水分和日照3个方面分析了该地区种植水稻的气候适宜性,和干旱、高温、暴雨和洪涝等气象灾害对水稻种植的影响。该地年平均温度14.6℃,平均降水量618.9mm,平均日照时数2041.5h;水稻生长期(5—10月)的平均温度在15.2~27.5℃,平均降水量521.5mm,平均日照时数1107.4h,其温度、降水及日照时数均满足水稻生长的需求。针对水稻提质增产,提出开展水稻专题气象服务,加强水稻田间管理等对策,为促进水稻产量和品质提高提供参考。
