This invention relates to the field of water-saving and fertilizer-retaining technology for fruit trees, and discloses a water-saving, fertilizer-retaining, and frost-resistant cultivation device for fruit trees. The device includes a pipe buried 80-120cm apart at a depth of 50cm in the planting row spacing of the fruit trees. The outer surface of the pipe has several absorption holes for draining water and fertilizer from the pipe. The top of the pipe is covered with a layer of sand and gravel and kraft paper to cover the absorption holes. This water-saving, fertilizer-retaining, and frost-resistant cultivation device and its method of use, by burying the nutrient trough precisely where most of the fruit tree's root system is located, only requires a small amount of water and fertilizer or nutrient solution to be injected. This avoids the large amount of fertilizer that accumulates in the soil and is not well absorbed and utilized by the roots, resulting in fertilizer waste and soil pollution, which is a consequence of trenching and spraying fertilization. It also saves water wasted on surface irrigation, achieving a good water-saving and fertilizer-retaining effect, and effectively prevents the serious impact of early spring frost on fruit tree flowering.
