Tree tray watering method
Open a clear ditch on one side of the tree tray and water the tree tray one by one. This method is suitable for areas with sufficient water source, and the water consumption is large, but it is easy to be poured and the effect is better.
2. Acupoint irrigation
This method should be used in places where water is inconvenient and watering is difficult. Dig 6 to 10 small holes under the canopy, the depth of the hole is 30 to 50 cm, the upper mouth is 30 cm in diameter, and the lower mouth is 40 cm in diameter. After filling the water, cover the mulch in the tree tray, or use the fallen leaves or weeds to cover the irrigation hole so that it can be used for the next refill or interception of rainwater.
3. Sprinkler irrigation
(1) Benefits of sprinkler irrigation: Sprinkler irrigation is a major reform and development of traditional ground irrigation methods. Since the 1950s, countries around the world have been widely used. Advantages of sprinkler irrigation
1 convenient. It is not limited by topography and climatic conditions, and has a wide range of applications. It is especially suitable for hilly areas with water shortage and drought, large soil water permeability and complex terrain.
2 province water. Sprinkler irrigation saves 30% to 50% of water compared to surface irrigation, and sandy soils save more water without destroying soil structure. 3 provincial workers. Sprinkler irrigation can be combined with fertilization and spraying, which saves a lot of labor. Under the same conditions, it is generally only about 25% of the amount of ground irrigation labor.
4 provinces. Sprinkler irrigation can save the field irrigation channels, and make full use of the land. Compared with the flood irrigation, it can save about 5%. In addition, it is also conducive to the mechanization of the orchard.
5 is also used. Adjust the microclimate of the orchard, prevent frost damage, promote fruit coloring, and control certain pests and diseases. In short, the comprehensive utilization of sprinkler irrigation projects will produce greater economic benefits.
(2) Sprinkler Irrigation System: The sprinkler irrigation system consists of water source, inlet pipe, water pump (power), water delivery pipe, vertical pipe (vertical short pipe connecting nozzle), pipeline accessories and nozzle. The water pump takes water from the water source and pressurizes it, and sends it to the orchard through the water pipeline system, and sprays water from the nozzle. The water pipeline can be divided into two grades and three grades. The second grade is the branch pipe (the pipe connecting the vertical pipe and the nozzle) and the main pipe (the pipe directly entering the source water), and the third level is the dry pipe, the dry pipe and the branch pipe. .
