非充分灌溉
On the basis of spring-wheat requiring-water regulation,referring to deficient irrigation experiment data of spring-wheat,and using dynamic programming theory,this thesis develops the optimization model of spring-wheat irrigation system. The aim of model is to reduce the irrigation quota during growing-period.
根据春小麦的需水规律，应用动态规划理论和非充分灌溉原理，参照灌区春小麦的非充分灌溉实验资料，以减小生育期的灌溉定额为目的，建立了春小麦灌溉制度优化模型。
