摘要
以田间试验数据为基础,结合地理信息系统、优化算法和植物模拟软件,以长春市合心镇为例,在土壤地理信息数据库的基础上构建优化区域玉米水肥耦合制度。结果表明,依据植物模拟软件和遗传算法能有效求解优化的玉米膜下滴灌水肥耦合制度,地理信息系统的建立能为农民的田间管理提供参考依据。
Based on the experiment data and taking HexinTown,Changchun as an example,the soil information system database and optimization of water and fertilizer coupling system are established with the combination of geographic information systems,optimization algorithm and crop model.The results show that the optimization of water and fertilizer coupling system can be solved efficiently in terms of crop model and genetic algorithms.A theoretical basis can be provided by building ageographic information system.
