Mulberry compound fertilizer and preparation method thereof

Abstract

The invention discloses a mulberry compound fertilizer, which is prepared from the following raw materials in parts by weight: 20-23 parts of urea, 24-28 parts of calcium superphosphate, 12-15 parts of humic acid, 13-16 parts of kieselguhr, 8-10 parts of tea shell powder, 3-4 parts of azedarach powder, 2-3 parts of garlic powder, 4-5 parts of carboxymethyl starch, 4-5 parts of calcium bicarbonate, 3-4 parts of ammonium molybdate, 5-6 parts of ferrous sulfate, 2-3 parts of copper sulfate, 1-2 parts of guar gum, 1-2 parts of zirconium oxide, 1-2 parts of methylcellulose, 3-4 parts of EM (effective microorganism) fungicide, 4-6 parts of film coating agent, and proper water. The fertilizer disclosed by the invention has the effects of inorganic and organic fertilizers; the nutrient elements required in the growth and development processes of mulberry can be reasonably configured, the growth requirements of the mulberry are met; the yield and the quality of the mulberry are improved, and the prepared fertilizer is not only quick to take effect, but also can slowly release the elements in the fertilizer; the property of the soil can be effectively improved by the added fungicide, and the utilization rate of the fertilizer is increased.

Description

[0001] technical field [0002] The invention relates to the technical field of fertilizers, in particular to a mulberry compound fertilizer and a preparation method thereof. Background technique [0003] 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 i...

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. not improved
