Computer Simulation of Irrigation Water Requirement for Paddy Rice

Irrigation management is of importance in agriculture, especially in the present since the lack of water resources. Automatic irrigation is a key part of modern agriculture resulting a higher production and lower water consuming. Water requirement estimation is the base of the determination of the irrigation regulation. Based on the information of climate, water and soil, a computer modelling of water requirement for paddy rice estimation was carried out and performed well in Qishitan Irrigation District, Guangxi.
