Beschreibung
Zusammenfassung:	The invention discloses a salix straw biomass carbon-based fertilizer and a preparation method thereof. The biomass carbon-based fertilizer comprises the following raw materials in weight part: 10-40 parts of salix straw biomass carbon, 20-50 parts of NPK compound fertilizer, 5-20 parts of grass carbon, 5-20 parts of faeces and 5-20 parts of bentonite. The salix straw biomass carbon heats salix straws from the normal temperature to 110-130 DEG C under the protection effect of nitrogen, then remains the temperature to be constant at 110-130 DEG C for 25-35 minutes, heats till the temperature to be 250-270 DEG C, remains the temperature to be constant at 250-270 DEG C for 25-35 minutes, heats till the temperature to be 390-410 DEG C, remains the temperature to be constant at 390-410 DEG C for 25-35 minutes, heats till the temperature to be 440-460 DEG C, remains the temperature to be constant at 440-460 DEG C for 25-35 minutes, cools till the temperature to be 250-270 DEG C, remains the temperature to be consta
