One kind of special long-acting slow-release fertilizer sugarcane

One kind of special long-acting slow-release fertilizer sugarcane, as slow-release fertilizer containing nitrogen, the ratio of P and K is N: P: K 20: 12: 5, by mass ratio of the raw materials: containing an amount of 49% and P2O5 MAP containing an amount of 9% N 96-190; P2O5 containing an amount of 18% FCMP 149-405; containing an amount of 46% N urea 398-416; K2O containing an amount of 83 to 60% potassium chloride; filler 0 -180. Clay filler and the dry mud filter press (3-7) :( 7-3) mixed mass ratio; dry water content of the mud filtrate 5% -10%. The present invention can effectively improve the germination rate of sugarcane, plant height and tillering, significantly increase the yield of sugar cane and sugar yield agriculture, tests showed yield increase sugar yield in sugar cane and sugar cane; cane significantly improve the quality, more suitable in southern China sugarcane field of application of fertilizer on the soil moderate tropical and subtropical.
