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500 mm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166.7~171.5 mm,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1800 MJ/(m^(2)·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6 h天数达19~23 d,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。
In the past 10 years(2011-2020),the average precipitation during the crop growth season in Lingdong Zhalantun City,Arong Banner,and Molidawa Banner of Hulunbuir City has exceeded 500 millimeters,which is very beneficial for promoting soybean and corn belt composite planting.However,the distribution of precipitation is uneven.The precipitation during the critical water period from mid July to early August is 166.7~171.5 millimeters,accounting for about 30%of the total precipitation during the growth period,which is lower than the ideal precipitation,There is a negative impact on the yield increase effect of soybean and maize belt composite planting;The total solar radiation in summer is above 1800 MJ/(m^(2)•a),which belongs to a region with abundant solar energy resources.The number of days with sunshine hours greater than 6 hours during the crop growth season can reach 19~23 days.The lighting conditions are very favorable for promoting soybean and corn belt composite planting.Meteorological disasters such as heavy summer rainfall,hail,and periodic droughts have a significant adverse impact on soybean and corn belt composite planting.
