喷灌对各种地形适应性强
喷灌对各种地形适应性强，不需要像地面灌溉那样整平土地，在坡地和起伏不平的地面均可进行喷灌。特别是在土层薄、透水性强的沙质土，非常适合采用喷灌。此外，喷灌不仅适应所有大田作物，而且对于各种经济作物、蔬菜、草场都可以获得很好的经济效果。 喷灌具有好多优点，但是也有缺点。主要是投资费用大，就目前条件移动式喷灌系统最便宜，亩投资也需要20-50元/亩。另外是受风速和气候的影响大，当风速大于5.5米/秒时 (相当于4级风)，就能吹散雨滴，降低喷灌均匀性,不宜进行喷灌。其次，在气候十分干燥时,蒸发损失增大，也会降低效果。
Sprinkler irrigation has strong adaptability to various topographies. It does not need to levelize the land like surface irrigation. Sprinkler irrigation can be carried out on sloping land and undulating ground. Especially in sandy soil with thin soil layer and strong permeability, sprinkler irrigation is very suitable. In addition, sprinkler irrigation not only adapts to all field crops, but also achieves good economic results for various cash crops, vegetables and grasslands. Sprinkler irrigation has many advantages, but it also has disadvantages. Mainly because of the high investment cost, the mobile sprinkler irrigation system is the cheapest at present, and the investment per mu also needs 20-50 yuan per mu. In addition, it is greatly influenced by wind speed and climate. When the wind speed is greater than 5.5 m/sec (equivalent to 4-grade wind), raindrops can be blown away, and the uniformity of sprinkler irrigation can be reduced, so it is not suitable for sprinkler irrigation. Secondly, when the climate is very dry, the evaporation loss will increase and the effect will be reduced.
