Abstract

The invention relates to a method for improving soil in a saline-alkali land. The method is characterized by comprising the following steps: (1) punching the soil and improving the harden degree of the soil; (2) fertilizing; and (3) watering. A fertilizer applied to the method for improving the soil in the saline-alkali land adopts a formula containing a microorganism organic fertilizer after greening waste treatment, fine sand and a plant growth regulator at a volume ratio of (70-80):(19-29):1. The method has the technical effects and advantages that 1, the punching fertilizing excellently solves the phenomenon that a sloping lawn cannot normally absorb water fertilizer and causes the lawn to vigorously grow; 2, the border trees treated by taking a punching ventilating nutriment-replenishing measure are characterized in that the blade color is deeper, the blade is fat and the leaves are lush; 3, the harden soil is loosened and the water-holding and fertilizer-retaining capabilities of the soil are enhanced; 4, the soil is improved and fertilized; and 5, the environmental protection is benefited.
