摘要
为满足新疆膜下滴灌棉花生产管理需要,研究开发了滴灌棉花灌溉决策支持系统。主要包含了数据库管理、实时墒情诊断、灌溉实时决策、生产管理决策等功能。使用水量平衡方法及消退系数法进行土壤墒情预报,使用泰森多边形等方法计算平均含水率,使用模糊综合评判进行灌溉实时决策。在实际使用中,能较准确的预测土壤墒情并实时指导田间灌溉,取得了预期的效果。
To satisfy the need of yield management of Xinjiang drip irrigation under plastic films on cotton,an irrigation decision support system for drip irration cotton is developed.It includes functions such as database management,realtime soil moisture diagnosis,irrigation realtime decision,production management and decision.Based on the water balance method and the fade index method to forcast soil moisture,Thiessen polygon method is used to calculate average moisture.Fuzzy synthesis judge method is used to make realtime irriation decision.In practice,an exact forcast result of soil moisture is gained and anticipative effect is gotten.
