The planting method comprises the following steps of greenhouse seedling raising, land preparation, field planting, small arched greenhouse erection, fertilizer and water management, timely picking, melon vine returning to fields and peach tree management. According to the method, the white gourds are interplanted, water, soil, light and heat resources in the peach orchard are fully utilized, ventilation and light transmitting of peach trees are not affected, the peach trees shade the white gourds and prevent burning, the white gourds can increase land cover and inhibit weed growth, and meanwhile the activity of soil enzyme is improved. Soil organic matter is increased for melon vine returning to the fields, the application amount of herbicides and fertilizers is decreased, the quality of peaches is ensured, and the economic benefits of the peach orchard are increased. By adopting the planting method, input is small, effect taking is quick, the economic benefits are obtained, the input of chemicals can be also decreased, and meanwhile the problem that the input is large and no return is obtained at an earlier stage of the peach orchard, and the earnings at middle and later stages are single is solved.
