- Abstract:
-
To explore the corn water production function suitability in central Guizhou, we combined with the test data of water consumption and maize yield under different irrigation treatments, and 5 kinds of water production function models including Jensen model, Minhas model, Blank model, Stewart model and Singh model are compared and analyzed. The results show that sequence λi of multiplication model Minhas model and maize water physiological characteristics do not match each other, the Ai of the addition of Blank model is the highest in the second stage, for the Stewart model, the Bi is the highest at 2 stage > 4 stages, at stage 3 and stage 5, the Ci in Singh model begins to turn to negative, which conflicts with the physiological characteristics of water and irrigation practice of corn, but calculating the water phase sensitive sequence and the corn moisture physiological characteristics and practical experience to irrigation by using Jensen model are accorded, Therefore, we determine that Jensen model is the most suitable model for corn water production function in central Guizhou.
