Problems solved by technology
During the early planting and production of melons, vegetables, and flowers, farmyard manure is often used. Although it can meet the growth needs of the above-mentioned crops to a certain extent, it cannot meet the needs of large-scale agricultural production for large amounts of fertilizers and high crop yields.
[0003] Modern agriculture mostly uses instant chemical fertilizers. Although they can meet the requirements of high crop yield and large demand, the above two commonly used fertilizers do not have the function of improving the quality of melons, vegetables, and flowers, nor can they satisfy people's desire for melons. On the basis of maintaining the original characteristics, fruits, vegetables and flowers have better color, aroma and taste characteristics or more ornamental requirements
Long-term use of instant chemical fertilizers will also cause soil compaction, deteriorate soil quality, and pollute water sources

Embodiment
[0015] Embodiment: the formula of the present invention is as follows:
[0016] More than 95% purity magnesium oxide (MgO) 20%
[0017] Monoammonium Phosphate (NH 4 h 2 PO 4 ) 60%
[0018] Potassium dihydrogen phosphate (KH 2 PO 4 ) 19%
[0019] water (H 2 O) 1%
[0020] Process of the present invention is as follows:
[0021] Put water equal to the total amount of each component of the formula into the reactor, then add 20% magnesium oxide (MgO) with a purity of more than 95%, stir for 15 minutes, heat the reactor system to 50°C, at this time, While stirring and heating continuously, add 60% monoammonium phosphate (NH 4 h 2 PO 4 ) and 19% potassium dihydrogen phosphate KH 2 PO 4 , continue to heat the reactor to 85°C, and stir for 2 hours to obtain 6 magnesium ammonium phosphate potassium double salts of crystal water ((NH 4 MGPO 4 ·6H 2 O) 4 · KMgPO 4 ·6H 2 0), then naturally cool down to 30°C, the reactant is removed from the reactor, and after solidi...

The invention discloses a production method of magnesium ammonium potassium phosphate full-nutrient slow-acting fertilizer used in the cultivation and production of melons, vegetables and flowers. The formula of the present invention is as follows: more than 95% purity magnesium oxide (MgO) 15-22%, monoammonium phosphate (NH 4 h 2 PO 4 )55-65%, potassium dihydrogen phosphate (KH 2 PO 4 )18-22%, water (H 2 O) 0.5-1.5%, after the finished product, the final proportioning ratio of each component combination should be 100%; the fertilizer effect of magnesium ammonium potassium phosphate fertilizer produced by the present invention can reach 1-2 years, clean, odorless and tasteless, not hurting the root system, crops It can absorb as much as needed, does not allow water loss, does not pollute the environment, promotes root development, enhances crop resistance, and has comprehensive and rich nutrition.
Description
technical field [0001] The invention discloses a production method of magnesium ammonium potassium phosphate full-nutrient slow-acting fertilizer used in the cultivation and production of melons, vegetables and flowers. Background technique [0002] Fruits, vegetables, and flowers need sunlight, water, and fertilizers during their growth. When fruits, vegetables, and flowers are planted and produced in the early stage, farmyard manure is often used. Although it can meet the needs of the above-mentioned crops to some extent, it cannot meet the needs of large-scale agricultural production for large amounts of fertilizers and high crop yields. [0003] Modern agriculture mostly uses instant chemical fertilizers. Although they can meet the requirements of high crop yield and large demand, the above two commonly used fertilizers do not have the function of improving the quality of melons, vegetables, and flowers, nor can they satisfy people's desire for melons. Fruits, vegetable...
