1. Water saving
Sprinkler irrigation can control the amount of water spray and uniformity of irrigation, avoiding the loss of surface runoff and deep leakage easily generated during ground irrigation, thus improving water use efficiency and saving irrigation water.
2. Increase production
Sprinkler irrigation can use shallow irrigation quota to carry out shallow pouring and digging of crops, which is convenient for strictly controlling soil moisture and making it more suitable for crop growth. Sprinkler irrigation does not cause mechanical damage to the soil of cultivated layer, and can maintain the structure of soil aggregates. Soil loose, porous, good ventilation conditions, promote nutrient decomposition, microbial activity, improve soil fertility; sprinkler irrigation can adjust field microclimate, increase near surface temperature, cool in summer, frost in winter, and can also wash on stems and leaves Dust, promotes breathing and photosynthesis, thus creating a good living environment for crops, promoting crop growth and development, and achieving the goal of increasing production.
3. Labor saving
Sprinkler irrigation can achieve a high degree of mechanization, greatly improving production efficiency, especially with the automatic operation of the sprinkler irrigation system, which can save a lot of labor. Sprinkler irrigation eliminates the water ditches in the field, reduces weed growth, eliminates the need to renovate ditches and remove weeds; sprinkler irrigation can also be combined with chemical fertilizers and pesticides, and can also save a lot of labor.
4. Provincial land
Sprinkler irrigation pipelines do not require irrigation ditches and rafts in the field. Under normal circumstances, dry, branch, bucket, agricultural, and furrows cover about 10-15% of the land. Compared with sprinkler irrigation, arable land can increase 7-10% of cultivated land.
5. Improve product quality
Practice in many places has proven that sprinkler irrigation not only increases production, but also improves product quality. Such as tea sprinkler irrigation, not only the production is improved, but the grade can also be improved. Sprinkling irrigation of fruit trees can greatly increase the proportion of primary and secondary fruits.
