通过对有豫南地区典型代表性的驻马店市夏玉米主要生育时段近30 a气象资料分析,找出了气候特点及对玉米生育阶段的影响,明确了降雨、积温、光照等气象因子对玉米生长发育的关系,得出豫南地区气候条件完全能够满足夏玉米生长发育的需要,只是年度间气象要素时空分布与玉米生育阶段的需要有时不相吻合而影响其产量的结论,并提出了可采取的应对措施,为促进豫南地区夏玉米生产提供了一定的科学依据.

Studies on the effects of main climate condition on summer maize growth and development in southern Henan and northern Henan, found the climate reason why the yield of southern Henan maize was lower than northern Henan maize. Taking southern Henan as emphasis and setting Zhumadian as typical representative of southern Henan and Xinxiang as typical representative of northern Henan, we compared and analyzed nearly 30 years meteorological datas between Zhumadian and Xinxiang during summer maize growth period, found the climate features of two locations and its influence on maize diffrent growth stages, and also found the relation between them. This article concluded that the climate condition of southern Henan could surely meet the needs of summer maize growth. But sometimes the output of summer maize was decreased by disaccord between the distribution of meteorological factors in time and space and the needs of maize different growth stages. Flooding,water logging, lacking of illumination, were main limiting factors in southern Henan. The ordering of restrict effect on maize high yield for southern Henan was rainfall, sunlight and temperature. So some countmeasure will be effectual, as veriaty choice,sowing data, clutivation and management, etc. These countmeasure will minimize the loss of maize production under adverse weather conditions.

在河南驻马店市对玉米新品种驻玉309分6个播期进行播期试验,通过对不同播期的生育期、株高、干物质积累、主要经济性状、产量分析比较,初步得出该品种在豫南地区的适宜播期为5月26日至6月20日,为该品种在豫南的高产栽培及大面积推广应用提供了一些科学依据。
