Paddy-upland rotation high-standard farmland control drainage design method and system based on DRAINMOD
The invention discloses a DRAINMOD-based paddy-upland rotation high-standard farmland control drainage design method, which comprises the following steps: performing field soil investigation, and determining a field arrangement condition and key soil parameters; constructing a DRAINMOD field hydrological model based on a soil survey result and designing a drainage system; based on the field hydrological model, a drainage system scheme meeting the mechanical harvesting requirement and a drainage system scheme eliminating farmland waterlogging in the wheat period are screened; determining a wheat season drainage system design scheme on the basis of meeting mechanical harvesting and wheat period waterlogging reduction requirements; and according to the wheat season drainage system design scheme and the rice season water management requirements, a drainage control operation mode is determined. By comprehensively considering the mechanical harvesting condition, the wheat season waterlogging reduction requirement and the rice season water resource management requirement, a set of drainage system operation mode capable of regulating and controlling the drainage intensity is provided, and the drainage intensity can be regulated and controlled while the waterlogging drainage and waterlogging reduction requirements in the harvesting season and the wheat season are met. The drainage intensity can be dynamically adjusted according to the water demand characteristic in the rice season, and the excessive irrigation water resource demand in the rice season is reduced.
本发明公开了基于DRAINMOD的水旱轮作高标准农田控制排水设计方法，包括：进行实地土壤调查，确定田间布置情况和关键土壤参数；基于土壤调查结果构建DRAINMOD田间水文模型并设计排水系统；基于田间水文模型筛选满足机械收割需求的排水系统方案和排除麦期农田渍害的排水系统方案；基于满足机械收割和麦期降渍需求确定麦季排水系统设计方案；根据麦季排水系统设计方案和稻季水管理要求确定控制排水运行模式。本发明通过综合考虑机械收割条件、麦季降渍需求与稻季水资源管理要求，提出一套可以调控排水强度的排水系统运行模式，在满足收割季和麦季的排涝降渍需求的同时，还能够根据稻季需水特点来动态调整排水强度、减少稻季的过度灌溉水资源需求。
