PVC lay flat hose has been welcomed by consumers repeatedly in the market. With the advent of spring, it is the most sensitive period for fruit trees to need water. In view of the fact that most of the orchards in the north have no irrigation conditions and the orchards in the South have abundant water but poor irrigation conditions, it is urgent to adopt water-saving irrigation. Popularizing the technique of storing fertilizer and water in caves is to dig round soil caves under tree crowns after thawing in spring, and to apply fertilizer, water and cover the plastic film. Infiltration irrigation is an irrigation method for pipeline seepage from the ground to the soil. It is a water-saving technology with less investment, less labor and high efficiency. The application cost of drip irrigation is low, labor-saving and simple. Drip irrigation, sprinkler irrigation and micro-sprinkler irrigation should be developed in mountain orchards according to local conditions, and irrigation methods should be carried out with the help of PVC lay flat hose and other irrigation tools. Dry well drilling technology has the effect of “summer rain and spring use”, and is also one of the common water-saving irrigation methods. Water-saving irrigation methods for orchard planting should not be simply limited, and irrigation tools such as PVC lay flat hose should also be improved and innovated in the development of demand.
