| Abstract: | This paper, based on the water balance principle of farmland soil, makes a dynamic simulation and analysis on moisture content changes of farmland in Hexi Oasis irrigation district in Gansu. The precision of simulating result is very high. The moisture content exponent is used to estimate actual situation of soil moisture content, and the exact date of irrigation is ascertained. The results provide a scientific basis for controlling soil moisture content, improving moisture content efficiency, and realizing water-saving and high-efficiency. |
