| Abstract: | Based on winter wheat growth rule in Henan province and application experience of optimal irrigation technique for winter wheat, the computer model of soil water prediction and optimal irrigation of winter wheat was set up according to soil water balance equation. Soil water can be predicted in one month ahead accurately with this model. Then irrigation suggestions according to wheat growth period can be given with the aims of obtaining the maximum yield and the optimal economic benefit. |
