利用黑龙江垦区玉米生长期的观测资料和垦区气象资料数据,对垦区玉米整个生长期的温度.日照.降水与气候产量进行通经与相关性分析,得出玉米产量与光.热.水三大要素关系数据,玉米的高产取决于单株粒重和果穗长度,气象因子在不同玉米发育期对果穗长度和粒重影响不同,在抽雄前平均气温和降水起直接作用;日照时数在播种后起直接作用;成熟期各气象因子起的作用较小。合理密植与加强田间管理也是使玉米高产的关键。
Based on the observation data of corn growing season and the reclamation area meteorological data of Heilongjiang reclamation area, the temperature, sunshine, precipitation and climate yield of reclamation area were analyzed and the correlations were analyzed. According to the data of elemental relationships, the high yield of maize depends on the grain weight per plant and ear length. The meteorological factors have different effects on ear length and grain weight at different stages of maize development, and have a direct effect on the average air temperature and precipitation before tasseling. After sunshine hours Play a direct role; meteorological factors play a minor role in maturity. Proper close planting and strengthening of field management are also the key to high yield of corn.
