Several irrigation techniques for northern wheat.

There are four ways of wheat drip irrigation:

1, surface irrigation: border irrigation in wheat field is an irrigation method created by working people in China. Generally, the boundary length is 30-50m, the boundary width is 2-3m, and the flow rate of each boundary width is 3-6L.

2. Sprinkler irrigation: compared with surface irrigation, it saves 20-40% water, does not destroy soil structure, and has a wide application range.

3. Drip irrigation: The advantage is water and energy saving. Not much is used for irrigation of wheat planting.

4. Underground pipeline water delivery and pipeline irrigation: the water delivery speed is fast, evaporation is reduced, cost is reduced, and land and labor are saved.
