摘要
对850试验区进行了降水、积温的限制因子分析,得出降水是作物产量主要限制因子,且该实验区旱涝频繁交替发生。利用建立的作物预测模型,得出小麦、玉米、大豆优化理论产量的气象因子数值。
This paper analyzed factors-precipitation, long-stand temperature in the experiment district in No. 850 Farm that precipitation was the main factor which effect the output of crops, and the experiment district frequently suffered drought and excessive rain. We invented a crop calculating model, and on the basis of this model, we found the meteorological factors which could lead to the theoretical optimum output of wheat, corn and rice.
