Background The south hilly area in China is the main production area of special fruits, but the problems of high underground water level, high air humidity, high soil viscosity and low mechanization level are commonly existed, and the industrial upgrading is seriously restricted. The existing orchard generally adopts open ditch drainage, although the drainage can be achieved, the ditches can not pass through agricultural machinery vertically and horizontally, the mechanical accessibility is less than 35%, the labor cost is high, and the requirements of mechanized development of fruit tree planting are contrary. The conventional concealed pipe drainage only aims at drainage, has no gas exchange function, is easy to cause anoxic decay of root systems of fruit trees due to long-term anoxic of deep soil in plum rainy seasons, and is difficult to popularize in mountain areas due to the fact that the conventional active oxygen supply technology depends on electric power, complex equipment and high operation and maintenance cost. The rainwater of the traditional system is directly discharged, cannot be recycled, causes water resource waste, and forms contradiction with the irrigation requirement in dry seasons. Meanwhile, the existing single-layer pipe network is difficult to adapt to the water-gas gradient requirements of the deep root fruit trees such as kiwi fruits and the like for different deep root systems, and the water-gas cooperative regulation and control of the whole root layer cannot be realized.
