Based on common by used crop water production function models, such as Doorenbos model, Jensen Model and Blank Model, equations used to estimate all types of SI are derived. The variation of the sensitive indies is also analyzed with experimental data. 关键词: crop sensitive index crop water ...
In this paper, crop water-production functions, namely crop water-yield models, of wheat, maize and cotton were analyzed and intrinsic relations among the different models advanced. Models of water-production function of different crops were fitted based on least-square theory using field experimental...
