Multi-element composite fertilizer and preparation method for same

Abstract

The invention discloses a multi-element composite fertilizer, which is prepared from the following raw materials in parts by weight: 120 to 130 parts of camellia seed shells, 10 to 12 parts of perlite, 2 to 3 parts of corundum powder, 2 to 3 parts of ceramsite, 1 to 2 parts of nanocarbon, 30 to 34 parts of urea, 20 to 23 parts of potassium chloride, 1 to 2 parts of magnesium oxide, 3 to 4 parts of magnesium sulfate, 1 to 2 parts of ferric sulfate, 2 to 3 parts of ammonium molybdate, 3 to 4 parts of EM agent, 4 to 6 parts of filming agent and a proper amount of water. According to the fertilizer, an organic fertilizer is mixed with an inorganic fertilizer, and the perlite, the corundum powder, the ceramsite, the nanocarbon and the like are added for reasonable blending, so that the formula is scientific and reasonable, and the fertilizer is wide in application range, and has strong and persistent fertilizer efficiency; the prepared fertilizer has certain nutritional value, and the growth and development of plants are promoted; the perlite, the corundum powder, the ceramsite, the nanocarbon and the like have remarkable improvement effects on the quality of soil, so that high quality and stable yield of various plants are ensured; due to the addition of the inorganic raw materials, the fertilizer contains multiple beneficial nutrient elements.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a multi-element compound fertilizer and a preparation method thereof. Background technique [0002] At present, my country's fertilizers are mainly chemical fertilizers composed of three inorganic elements, N, P, and K. This chemical fertilizer can meet the growth needs of crops in a short time. However, long-term use will damage the soil aggregate structure, which will easily cause soil compaction and soil hardening, which will affect the growth of crops and the decline in quality, resulting in a vicious circle. At the same time, although the organic fertilizer is rich in organic matter, the release of nutrients is slow, resulting in slow absorption of crops, low fertilizer efficiency, and no effective balance between various effective nutrients. Due to the unscientific fertilizer formula for crops, the yield of crops is not high and the quality is also low. Can't be improv...
