Abstract

The invention discloses a coated fertilizer for promoting the growth of a strawberry root system. The coated fertilizer is characterized by being prepared from the following raw materials in parts by weight: 19-26 parts of sauce residue powder, 14-19 parts of waste Chinese medicine residue powder, 0.4-1.0 part of ferrous sulfate, 0.3-0.5 part of manganese sulfate, 0.03-0.05 part of NAA, 0.06-0.2 part of compound sodium nitrophenolate, 3-5 parts of vermiculite powder, 10-13 parts of green grass powder, 12-15 parts of rice bran, 16-21 parts of rape seed cake, 15-19 parts of ammonium dihydrogen phosphate, 1-2 parts of dicyandiamide, 3-5 parts of tung oil, 13-16 parts of sweet wormwood extract, 7-14 parts of urea, 7-9 parts of EM bactericide, 9-12 parts of soil conditioner and a proper amount of water. Nutrient elements which are balanced in a nutrient formula and furthest meet the growth requirement of crops are designed according to low strawberry reproduction coefficient and low multiplication rate, and the fertilizer is released slowly, has the effects of protecting soil, killing pests and adsorbing harmful substances in soil, is rich in nutrients and provides a good growth environment for growth and multiplication.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a coated fertilizer for promoting the growth of strawberry roots and a preparation method thereof. Background technique [0002] Coated fertilizer is a kind of slow-release fertilizer made by coating other substances on the surface of fertilizer particles. The substances used for film formation include natural products and artificially synthesized polymers such as polyurethane, polyethylene, paraffin, and oil. , asphalt and sulfur, etc. After they form a film, they can reduce the direct contact between fertilizers and the outside world, control the release rate of nutrients in water-soluble fertilizer particles, and improve the physical and chemical properties of fertilizers. Basically, except for sulfur, most of the coating materials are non-plant nutrients, so the coating layer is not allowed to be too thick. But in order to form a complete sealing layer, it should not be too thin. ...
