- The drip irrigation system saves water by 30% -40% compared with ground furrow irrigation, thereby saving the energy consumption of pumped oil and electricity.
- The drip irrigation water volume is small, and it is not a short-time irrigation, so the direct impact on the ground temperature is small. Moreover, drip irrigation is to irrigate the water in the underground root zone. The amount of ground evaporation water is small, reducing the soil evaporation heat consumption. Therefore, the ground temperature of drip irrigation vineyards is generally higher than that of traditional ground irrigation, so the grapes grow fast and mature early. This is even more significant in facility cultivation.
- Drip irrigation is to use drip infiltration to supply water to the soil without causing damage to the soil structure.
- Because the ground evaporation is greatly reduced, the relative humidity of the air around the canopy of the vineyard is reduced by about 10% compared with the ground irrigation, thereby greatly causing the occurrence and spread of pests and diseases.
- Reduced the chances of spreading and re-infecting certain diseases, especially root cancer, that are transmitted by irrigation water.
- Drip irrigation combined with top dressing and fertilizer application improves labor productivity. A facility fertilizer device is attached to the drip irrigation system, and the fertilizer is sent to the vicinity of the root zone along with the irrigation water, which not only saves fertilizer, but also improves fertilizer efficiency and saves fertilizer. Some pesticides used for soil disinfection and applied from the roots can also be applied to the soil by drip irrigation, thereby saving labor costs and improving the effect of medication.
- Drip irrigation is a semi-automatic mechanical irrigation method. The installed drip irrigation equipment, as long as the valve is opened and adjusted to the appropriate pressure, it can irrigate itself.
Through the above description, the drip irrigation system in the vineyard is more advantageous than the traditional furrow irrigation and sprinkler irrigation.
