通过建立冬小麦的气温适播期模型、土壤湿度模型和机器可下地作业模型等3个定量化模拟模型,对山西省临汾地区的冬小麦机械播种情况进行了实例模拟,结果与实际符合较好。 Three quantitative simulation models were established for winter wheat such as temperature suitable sowing date, soil moisture model and machine subsoil operation model. The mechanical sowing of winter wheat in Linfen, Shanxi Province was simulated. The results are in good agreement with the actual situation.
