Method for preventing fertilizers of terraces from being polluted

The invention provides a method for preventing fertilizers of terraces from being polluted. The method for preventing the fertilizers of the terraces from being polluted is used for applying soil structure conditioners, soil water-holding agents and plant antitranspirants to fruit trees planted in the terraces. On odd number-step terraces (1, 3, 5), the soil structure conditioners are evenly spread within the whole farmland range. On even number-step terraces (2, 4, 6), the soil structure conditioners are evenly spread to a zonal land surface from 1 / 3 to 2 / 3 of the vertical projection radius of the canopy of each fruit tree. According to the method provided by the invention, through comprehensively controlling multiple migration paths, such as infiltration, holding, leaching, uptake and utilization of liquid fertilizers of the terraces with different steps, through functions of reducing leaching leakage and evaporation and the transpiration loss of the liquid fertilizers, holding the liquid fertilizers at root layers of crops and promoting crop physiology functions, the efficient utilization of the liquid fertilizers of terrace orchards is realized. The method provided by the invention is fewer in input, easy in operation and high in applicability and is suitable for being popularized and applied to the terrace orchards. As the utilization rate of the liquid fertilizers and the crop physiology functions are improved, the environmental pollution level is lower.
