| 摘 要： | 根据栽培地的热量资源及玉米生育期所需的热量指标。确定不同品种在不同地区的成熟度；利用概率决策方法，计算同一气候条件下不同品种的成熟度和品种间的产量差异。来确定当地的主栽品种；采用线性规划方法综合考虑栽培地区的热量年际波动状况，对当地不同熟型玉米品种种植比例进行了搭配，以充分合理利用当地热量资源，优化玉米品种布局，达到主动防御低温冷害的目的。

| Abstract: | The maturity degree was determined according to the developmental stages and heat index of different maize varieties and temporal heat resource. Because of the maturity degree of different varieties under the same climate condition and the yield difference between varieties, the main planting variety was determined by using probability decision. Using linear programming,the inter annual fluctuation of regional heat was considered comprehensively. The planting rate of different maturity varieties were arranged to reach fully and reasonable use heat resource. Making a better maize varieties structure is the aim of active defending to chilling damage. |
