How much water can be saved by using water-saving methods such as drip irrigation and sprinkler irrigation for agricultural irrigation? The difference between drip irrigation and sprinkler irrigation

Compared with traditional surface irrigation, sprinkler irrigation can save about 40-50% of water, and compared with sprinkler irrigation, drip irrigation can save about 33% of water. Compared with border irrigation, , can save about 81.6% of water. Differences: 1. Drip irrigation drips irrigation water directly into the soil, while sprinkler irrigation sprays irrigation water into the air to form water droplets that fall to the surface of plants and soil. 2. Compared with sprinkler irrigation, drip irrigation saves more water and electricity, and the water utilization rate is also higher. 3. Sprinkler irrigation is greatly affected by wind speed and climate.

1. How much water can be saved by using water-saving methods such as drip irrigation and sprinkler irrigation for agricultural irrigation?

1. Sprinkler irrigation

(1) Sprinkler irrigation mainly relies on pipes. Sprinklers spray water for irrigation onto the soil surface and onto plants.

(2) Compared with traditional surface irrigation, sprinkler irrigation can save about 40-50% of water.

2. Drip irrigation

(1) Drip irrigation mainly uses special pipeline systems and equipment to deliver water to the irrigation area, and then slowly and evenly drips the water into the soil at the roots of the crops.

(2) Compared with sprinkler irrigation, drip irrigation can save about 33% of water, and compared with border irrigation, it can save about 81.6% of water.

3. Water transmission and irrigation through anti-seepage channels

Changing the earthen channels that transport irrigation water into anti-seepage channels can save about 20% of water.

4. Pipe irrigation

Laying pipes on the ground or underground, and then transporting irrigation water to the fields through the pipes, can save 30-50% of water compared with earth canal water irrigation. %about.

2. The difference between drip irrigation and sprinkler irrigation

1. Drip irrigation uses pipes to drip irrigation water directly into the soil, while sprinkler irrigation sprays irrigation water into the air to form water droplets. Lands on plants and soil surfaces.

2. Compared with sprinkler irrigation, drip irrigation is more water-saving (approximately 33% water saving), energy-saving (approximately 41.3% electricity saving), and the water utilization rate is also higher (drip irrigation, water The utilization rate is about 95%, for sprinkler irrigation, the water utilization rate is about 80%).

3. Sprinkler irrigation is greatly affected by wind speed and climate. When the wind speed is greater than 5.5m/s, the water droplets will be blown away, reducing the uniformity of sprinkler irrigation, thereby affecting the effect of sprinkler irrigation. In addition, when the weather is very dry, the loss of water droplets sprayed into the air is greater, which will also reduce the effect of sprinkler irrigation.

4. Sprinkler irrigation is an intermittent water supply, while drip irrigation is a continuous water supply, and compared with drip irrigation, sprinkler irrigation is more likely to cause an increase in air humidity.
