Embodiment 1

[0020] First, weigh 10 parts of diammonium phosphate and add it to the stirring device to stir and dissolve, stir for 10-20mmin to filter, then put 2 parts of dicyandiamide into the stirring device to dissolve, take a small amount of water for injection, and then weigh 20 parts of urea Put one part into the stirring device to dissolve, then take a small amount of water for injection, then weigh 2 parts of ferrous sulfate and put it into the stirring device to dissolve, then take a small amount of water for injection, then weigh 4 parts of calcium oxide and put it into the stirring device At the same time, put 3 parts of magnesium sulfate and 2 parts of elemental salt for mixing and dissolving to obtain a compound fertilizer, and finally put 110 parts of nutrient solution for mixing and dissolving, mix the nutrient solution and compound fertilizer, and use Stir with a stirrer for 15-17 minutes, react at a constant temperature until the solution is clear, and obtain a special liq...

Embodiment 2

[0022] First, weigh 12 parts of diammonium phosphate and add it to the stirring device to stir and dissolve, stir for 10-20 minutes to filter, then put 3 parts of dicyandiamide into the stirring device to dissolve, take a small amount of water for injection, and then weigh 25 parts of urea Put one part into the stirring device to dissolve, then take a small amount of water for injection, then weigh 4 parts of ferrous sulfate and put it into the stirring device to dissolve, then take a small amount of water for injection, then weigh 5 parts of calcium oxide and put it into the stirring device At the same time, put 4 parts of magnesium sulfate and 3 parts of elemental salt to mix and dissolve to obtain a compound fertilizer, and finally put 125 parts of nutrient solution to mix and dissolve, mix the nutrient solution and compound fertilizer, and use a machine with a rotation speed of 340-360r / min Stir with a stirrer for 15-17 minutes, react at a constant temperature until the sol...

Embodiment 3

[0024] First, weigh 14 parts of diammonium phosphate and add it to the stirring device to stir and dissolve, stir for 10-20 minutes to filter, then put 4 parts of dicyandiamide into the stirring device to dissolve, take a small amount of water for injection, and then weigh 30 parts of urea Put one part into the stirring device to dissolve, then take a small amount of water for injection, then weigh 6 parts of ferrous sulfate and put it into the stirring device to dissolve, then take a small amount of water for injection, then weigh 6 parts of calcium oxide and put it into the stirring device At the same time, put 5 parts of magnesium sulfate and 4 parts of elemental salt to mix and dissolve to obtain a compound fertilizer, and finally put in 140 parts of nutrient solution to mix and dissolve, and mix the nutrient solution with the compound fertilizer. Stir with a stirrer for 15-17 minutes, react at a constant temperature until the solution is clear, and obtain a special liquid ...

Abstract

The invention relates to the technical field of liquid fertilizer manufacturing, and discloses a special liquid fertilizer for a greenhouse. The special liquid fertilizer is prepared from the following ingredients including 110 to 140 parts of nutrition solution, 10 to 14 parts of diammonium phosphate, 2 to 4 parts of dicyandiamide, 20 to 30 parts of urea, 2 to 6 parts of ferrous sulfate, 4 to 6 parts of calcium oxide, 3 to 5 parts of magnesium sulfate, 2 to 4 parts of element slat and the balance of water. The special liquid fertilizer for the greenhouse and a application method thereof havethe advantages that the nutrition liquid is used, so that the nutrition ingredients of the liquid fertilizer can be improved; meanwhile, chemical ingredients in the fertilizer can also be reduced, sothat the effect of the liquid fertilizer during the fertilization on crops can be greatly improved; then, through the mixing of the nutrition liquid and the composite fertilizer, the liquid fertilizercan be prepared; the prepared liquid fertilizer can promote the crop growth; meanwhile, the yield of the crops can be effectively improved; therefore the quality of the crops can be improved; the residue of chemical fertilizers and pesticide in the crops can be reduced; the eating safety of the crops can be ensured.

Description

technical field [0001] The invention relates to the technical field of liquid fertilizer production, in particular to a special liquid fertilizer for greenhouses and an application method thereof. Background technique [0002] Greenhouses, also known as greenhouses, can transmit light, keep warm (or heat), and are used to cultivate crops. In seasons that are not suitable for crop growth, they can provide greenhouse growth periods and increase production. They are mostly used for temperature-loving vegetables and flowers in low-temperature seasons. There are many types of greenhouses, which can be divided into many types according to different roof truss materials, lighting materials, shapes and heating conditions. The types of greenhouses include planting greenhouses, breeding greenhouses, exhibition greenhouses, experimental Greenhouse, catering greenhouse, entertainment greenhouse, etc.; the design of the greenhouse system includes heating system, heat preservation system,...
