Improving the irrigation technology and integrated water saving modes, The main technique is farmland alteration, the irrigation area of each farmland decreased to about 0.3mu, can save water 4.39billion m~3.
Using the fuzzy evaluation method to Sanhe agricultural experiment fields,Hebei Province,the water-saving(benefit) was evaluated from three ways including direct water-saving effect,direct water-saving economic benefit and social influence. The results indicate that the pattern of pea+spring corn has the highest score,then the pattern of spring corn and spring corn+winter wheat+summer corn,the(synthetic) pattern Ⅲ and Ⅳ have obvious water-(saving) benefit.
Five comprehensive water-saving models were integrated based on long-term experiments on different single water-saving measures for maize and winter wheat in the high yielding area of Hebei Plain. The five comprehensive models include water transportation through soil ditch+minimum tillage and mulching+regulated deficit irrigation scheduling; water transportation through main pipe line+minimum tillage and mulching+regulated deficit irrigation scheduling; water transportation through main pipe line and gat...
