The invention discloses a
biomass charcoal-based compound
fertilizer for wheat. The
biomass charcoal-based compound
fertilizer comprises the following components in parts by weight: 8 to 14 parts of
potash magnesium sulphate
fertilizer, 12 to 17 parts of
potassium chloride, 6 to 13 parts of fertilizer-level
calcium hydrophosphate, 13 to 21 parts of
urea phosphate, 30 to 40 parts of powdery
urea, 8 to 14 parts of soybean
straw powdered carbon, 2 to 7 parts of
sodium silicate, 1 to 4 parts of EDTA chelate Zn, 1 to 4 parts of EDTA chelate Fe, 1 to 5 parts of
ammonium molybdate and 3 to 7 parts of an auxiliary material. The invention further discloses a preparation method for the
biomass charcoal-based compound fertilizer special for the wheat. According to the invention, after the biomass charcoal-based compound fertilizer special for the wheat is applied, not only can soil be effectively improved and fertilized, the content of
soil organic matter can be increased, the volume weight of soil can be reduced, and the
water retention and fertilizer retention capabilities of the soil can be improved, but also the fertilizer
nutrient utilization efficiency is relatively high,
nutrient element release is coordinated and lasting,
nutrient can be supplied to the wheat relatively comprehensively and evenly, the output of the wheat can be obviously improved, the quality of the wheat can be improved, and obvious economic benefit can be achieved.
