What advantages does a center-pivot sprinkler irrigation machine have compared with traditional sprinkler irrigation machines?
The center-pivot sprinkler irrigation machine is a type of sprinkler irrigation, a simple sprinkler irrigation machine that can be driven either electrically or hydraulically, and is widely used in areas with relatively extensive cultivated land. It is a multifunctional self-propelled sprinkler irrigation machine. So what advantages does the center-pivot sprinkler irrigation machine have compared with traditional sprinkler irrigation machines?
1. Saves water
Because the water conveyance loss of a sprinkler irrigation system is extremely small, it can control the irrigation intensity and irrigation volume well, irrigate evenly, and achieve a high water utilization rate. The irrigation uniformity of sprinkler irrigation can generally reach 80%-85%, the effective utilization rate of water is above 80%, and the water consumption is 30%-50% less than that of surface irrigation.
2. Saves labor
Because the sprinkler irrigation system is highly mechanized, it does not require manual construction of ridges or canal repair, can greatly reduce the labor intensity of irrigation, and saves a large amount of labor. Compared with surface irrigation methods, it can increase efficiency by 20-30 times.
3. Increases crop yield
Because irrigation water is transported and distributed to the field through various sprinkler irrigation devices, all of which operate under controlled conditions, precise water supply can be carried out according to water supply conditions and crop water requirements. In addition, sprinkler irrigation can also regulate the field microclimate. Using sprinkler irrigation in dry-hot wind seasons to increase air humidity and lower air temperature can achieve good results; in early spring, sprinkler irrigation can be used to prevent frost. Practice shows that sprinkler irrigation can increase yield by 15%-25% compared with surface irrigation.
4. Has strong adaptability
A prominent advantage of sprinkler irrigation is that it can be used for various types of soil and crops and is subject to little restriction from terrain conditions. For example, sprinkler irrigation can be used on sandy soil or where the terrain slope reaches 5% and surface irrigation is difficult. In areas with a high groundwater table, surface irrigation makes the soil too wet and easily causes soil salinization, while sprinkler irrigation can be used to regulate the moisture status of the upper soil layer and avoid the occurrence of salinization. Because sprinkler irrigation has low requirements for terrain, it can save a large amount of engineering work for leveling farmland.
5. Improves cultivated land utilization rate
The use of sprinkler irrigation can greatly reduce the land occupied by internal field ditches and ridges, increase the actual sown area, and increase the cultivated land utilization rate by 7%-15%.
