Abstract

The invention discloses an attapulgite based fertilizer for improving soil. The attapulgite based fertilizer for improving the soil comprises the following components in percentage by mass: 12-18% of thifluzamide, 25% of superphosphate, 2.6-4.3% of a dispersing agent, 5.5% of sodium dodecyl benzene sulfonate, 15% of attapulgite, 2.2-4.5% of urea, 2% of a coolant, 0.5% of an antifoaming agent SAG622, and the balance of deionized water. The preparation method comprises the following steps: crushing, roasting and acidizing attapulgite; then mixing with the rest materials based on the mixing ratio; and finally transferring into a sanding cup to be sanded. According to the fertilizer prepared by the method, attapulgite clays are subjected to heat treatment to enable a disorderly-deposited bundle rod shaped structure to be loose and porous; the specific surface of an attapulgite crystal can be increased through the acid activation treatment, and thus the absorbing capacity can be effectively improved. The prepared attapulgite based fertilizer has the effects of performing sterilization and supplying nutrition to crop.
