文章编号：1673-887X(2023)05-0169-03呼伦贝尔市气候条件对大豆玉米带状复合种植的影响分析赵岳冀（呼伦贝尔市气象局，内蒙古自治区呼伦贝尔021000）摘要2011年—2020年呼伦贝尔市岭东扎兰屯市、阿荣旗和莫力达瓦旗作物生长季降水量平均值达500mm以上，对推广大豆玉米带状复合种植十分有利，但降水分布不均，7月中旬—8月上旬水分临界期降水量在166.7~171.5mm，约占生育期总降水量的30%，低于理想降水量，对大豆玉米带状复合种植的增产效果有不利影响；夏季太阳总辐射在1800MJ/(m2·a)以上，属于太阳能资源很丰富区，作物生长季日照时数大于6h天数达19~23d，光照条件对于推广大豆玉米带状复合种植十分有利；夏季强降水、冰雹和阶段性干旱等气象灾害对大豆玉米带状复合种植的不利影响较大。关键词呼伦贝尔市；大豆；玉米；带状复合种植；气象灾害中图分类号S513；S565.1S344.3文献标志码Adoi:10.3969/j.issn.1673-887X.2023.05.064AnalysisoftheImpactofClimaticConditionsonSoybeanandMaizeBeltCompoundPlantinginHulunbuirCityZhaoYueji(HulunbuirMeteorologicalBureau,Hulunbuir021000,InnerMongoliaAutonomousRegion,China)AbstractAbstract：Inthepast10years(2011-2020),theaverageprecipitationduringthecropgrowthseasoninLingdongZhalantunCity,ArongBanner,andMolidawaBannerofHulunbuirCityhasexceeded500millimeters,whichisverybeneficialforpromotingsoy‐beanandcornbeltcompositeplanting.However,thedistributionofprecipitationisuneven.Theprecipitationduringthecriticalwa‐terperiodfrommidJulytoearlyAugustis166.7~171.5millimeters,accountingforabout30%ofthetotalprecipitationduringthegrowthperiod,whichislowerthantheidealprecipitation,Thereisanegativeimpactontheyieldincreaseeffectofsoybeanandmaizebeltcompositeplanting;Thetotalsolarradiationinsummerisabove1800MJ/(m2•a),whichbelongstoaregionwithabun‐dantsolarenergyresources.Thenumberofdayswithsunshinehoursgreaterthan6hoursduringthecropgrowthseasoncanreach19~23days.Thelightingconditionsareveryfavorableforpromotingsoybeanandcornbeltcompositeplanting.Meteorologicaldi‐sasterssuchasheavysummerrainfall,hail,andperiodicdroughtshaveasignificantadverseimpactonsoybeanandcornbeltcom‐positeplanting.Keywords：HulunbuirCity,...
