Water Requirement Calculation of Planted Fodder and Validity Examination
人工牧草需水量的模拟计算及其有效性检验

Simulation precision of crop water requirement is very important for water saving irrigation system design,irrigation and drainage system planning and scientific allocation of water resources.Common approaches used for simulating crop water requirement include FAO-56 dual crop coefficient approach,two source model of conservation of energy fluxes,and water balance model of root zone,and SWAP model.Before the calculated crop water requirement is applied in practice,its validity should be examined.The crop wa...
