土壤 作物模拟模型已成为向农业生产管理决策提供科学依据的一个有效工具 .APSIM (AgriculturalProductionSystemSimulator)模型是澳大利亚科学家开发研制的 ,用于模拟农业系统各生物过程 ,特别是气候风险下系统各组分生态和经济输出的机理模型 .APSIM已在温带大陆性气候、温带海洋性气候、亚热带干旱气候和地中海气候带下的粘土、胀缩土 (duplex)、变性土 (vertisol)、粉粒砂壤、粉粒壤土和粉粒粘壤土等土壤上进行了验证和应用 ,可以用于小麦等 2 0余种作物的模拟 .APSIM模型在作物结构和轮作序列调整、作物产量、质量预测和控制及不同种植方式下水土流失调控等方面具有良好的描述能力
Soil crop simulation model has become an effective tool to provide a scientific basis for agricultural production management decision-making.APSIM (Agricultural Production SystemSimulator) model developed by Australian scientists to simulate the biological processes in agricultural systems, especially the risk of climate system components ecosystem And the mechanism model of economic output.APSIM has been developed in temperate continental climate, temperate maritime climate, subtropical arid climate and the Mediterranean climate zone of the soil, the expansion of soil (duplex), vertisol, silt sand, powder Grained loam and silty clay loam so that it can be used to simulate more than 20 kinds of crops such as wheat.APSIM model is applied to crop structure and rotation sequence adjustment, crop yield, quality prediction and control and different planting methods Soil erosion control and other aspects of a good description of the ability
