Winter Wheat Water Consumption and Insufficient Irrigation System in Different Hydrological Years in North Henan Province
Abstract：The winter wheat water consumption in north Henan Province was studied in the paper,it was showed that stooling stage and booting stage were two peaks of whole growth stage water consumption,the latter was 65% of the whole water consumption.In the paper,Jensen model was solved by dynamic programming and insufficient irrigation system was established on the condition that different hydrological years and different irrigation norms in this area,it was show that jointing stage and filling stage should be irrigated firstly under the condition of water shortage,and when water was sufficient,the water of the seeding stage and turning green stage should be guaranteed.
