侯马地区玉米生育期气象条件分析

Meteorological Conditions Analysis of Corn Growth period in Houma

本文通过对比侯马地区玉米生长发育的气象指标和玉米生育期H照、温度、降水等气象条件，分析侯马地区春、夏玉米不同生育阶段的光照、热量及降水等气候资源及其对春玉米和夏玉米不同生长发育时期的影响。分析结果显示，侯马地区春玉米的适宜生长期较长，除苗期日照时数略有不足外，温度、降水等气候资源与春玉米的生育需求较为吻合；夏玉米的适宜生长期较短，日照时数略低，生长后期温度降低，不利于淀粉转化和物质积累，生育阶段较易遭受‘初夏旱’、‘卡脖旱’等气象灾害。春玉米的种植可以选用早、中熟甚至晚熟品种，夏玉米种植应尽量选用生长期短的早熟品种，抢收抢种。生长需水时期应充分利用汾河浍河水系及时进行灌溉。

By comparing the meteorological indicators and the sunshine, temperature, precipitation and other meteorological conditions in corn growing and development in Houma, the effect of light, heat and precipitation in different growth stages of sprint and summer corn was analyzed. The results show that the spring corn in Houma is suitable for longer growing season. The number of hours of sunshine is less slightly in the seedling stage. The temperature and precipitation and other climate resource satisfied with the need of spring corn in Houma. The summer corn in Houma is suitable for shorter growing season.
