(1) Sprinkler irrigation: suitable for mountain, slope, and unfinished grass orchards. There are two types of sprinkler irrigation: fixed or mobile. The height of the nozzle is above the crown, the center of the crown, and around the trunk. The advantage of this method is to save water and save labor. In addition to irrigation, it also takes into account some spraying, fertilizing and hormonal operation, and can prevent frost in spring and high temperature in summer, which will increase fruit production by 5~10%. The use of this method requires special equipment, and the investment is more. The facility stays in the orchard for a long time, and it is difficult to take care of it. In recent years, the application has become less and less.

(2) Drip irrigation: It is a new type of water-saving irrigation method worth promoting. Drip irrigation can provide continuous water supply for local roots, soil structure is maintained well, and water status is stable. This method is more water-saving and labor-saving than sprinkler irrigation, and has a significant effect on preventing secondary salinization of soil, which can increase production by 20-30%. Especially for droughts, orchards with severe water shortages are more suitable. The drip irrigation system consists of a pump, a filter, a pressure regulating valve, a flow regulator, a water channel, and a dripper. The number of drip irrigations and the amount of water are determined by soil moisture and water requirements of the fruit trees. In the spring drought, it can be drip every day, usually once every 2~3 days. Each irrigation is 3 to 6 hours, and each drip is dripped 2 kg per hour. The first drip irrigation will make the soil moisture saturated, and the soil moisture will be kept at about 70% of the maximum water holding capacity in the field.
