Study on Jensen Model at Each Growing Stage for Main Crops in China
Zugui Liu · Jieshui guan'gai · 2008
Through analysis of the water production function at each growing stage of crops,it is indicated that Jensen models has good expression in the relationship between water consumption at each growing stag(?) and yields.Based on it,the Jensen models for main crops in many areas of China are established by using the relevant irrigation scheduling data from the database of national irriga- tion experiment and some irrigation experimental stations.In addition,the characteristics of the models and problems possibly exist- ing in the application of the models are discussed.
