Embodiment 1

[0044] A kind of alkaline fertilizer proportioning is made up of following raw material by weight percentage: urea (pH7.0) 84.8%, potassium pyrophosphate (pH10.5) 14.3%, EDTA calcium (pH7.5) 0.8%, sodium molybdate ( pH9.0) 0.1%. The various nutrient contents of the alkaline fertilizer are: nitrogen 39%, phosphorus pentoxide 6%, potassium oxide 8%, calcium 0.08%, molybdenum 0.04%, and the pH value of the product is 7.5. All kinds of raw materials can be crushed, measured, mixed, weighed and packaged.

[0045] The pH value of the alkaline fertilizer=7*84.8%+10.5*14.3%+8*0.8%+9*0.1%=7.5

Embodiment 2

[0047] A kind of alkaline fertilizer proportioning is made up of following raw material by weight percentage: urea (pH7.0) 1.0%, diammonium phosphate (pH8.0) 69.3%, potassium pyrophosphate (pH10.5) 26.8%, EDTA magnesium (pH7 .0) 2.7%, sodium octaborate tetrahydrate (pH9.0) 0.2%. The various nutrient contents of the alkaline fertilizer are as follows: 15% of nitrogen, 48% of phosphorus pentoxide, 15% of potassium oxide, 0.16% of magnesium, 0.04% of boron, and the pH value of the product is 8.6. All kinds of raw materials can be crushed, measured, mixed, weighed and packaged.

[0048] pH=7*1.0%+8.0*69.3%+10.5*26.8%+7.0*2.7%+9.0*0.2%=8.6

Embodiment 3

[0050] A kind of alkaline fertilizer ratio is composed of the following raw materials by weight percentage: urea (pH7.0) 1.1%, potassium pyrophosphate (pH10.5) 9.5%, potassium nitrate (pH7.0) 70.2%, potassium carbonate (pH11. 6) 15.5%, calcium EDTA (pH7.5) 2.8%, borax (pH9.0) 0.75%, sodium molybdate (pH9.0) 0.15%. The various nutrient contents of the alkaline fertilizer are: 10% of nitrogen, 5% of phosphorus pentoxide, 50% of potassium oxide, 0.28% of calcium, 0.08% of boron, 0.05% of molybdenum, and the pH value of the product is 8.1. All kinds of raw materials can be crushed, measured, mixed, weighed and packaged.

[0051] PH value=7*1.1%+10.5*9.5%+7*70.2+11.6*15.5%+8*2.8%

[0052] +9*0.75%+9*0.15=8.1

Abstract

The invention discloses an alkaline fertilizer composed of the following components in percentage by weight: 31-99.4% of macroelements, 0.5-50% of medium elements, 0.1-15% of microelements and 0-50% of synergic components, wherein the macroelements include two and even more selected from urea, diammonium phosphate, ammonium polyphosphate, dipotassium phosphate, tripotassium phosphate, potassium pyrophosphate, potassium tripolyphosphate, potassium nitrate, potassium carbonate, potassium sulfate, potassium chloride, potassium formate, potassium silicate and potassium hydroxide; the medium elements are one or more selected from calcium nitrate, calcium chloride, magnesium chloride, magnesium sulfate, EDTA calcium and EDTA magnesium; the microelements are one or more selected from ferrous sulfate, zinc sulfate, manganese sulfate, copper sulfate or an EDTA chelate of iron, zinc, manganese and copper, EDDHA iron, borax, disodium octaborate tetrahydrate and sodium molybdate; and the synergic components include one or more selected from sodium humate, potassium humate, sodium fulvate, potassium fulvate, sodium alginate, potassium alginate and a plant growth regulator.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an alkaline fertilizer with the effects of inhibiting soil acidification and improving acidic soil and having a pH value greater than 7.0. Background technique [0002] The nutrients needed by plants include macroelements (such as nitrogen, phosphorus, potassium), secondary elements (such as calcium, magnesium, sulfur), microelements (such as boron, zinc, iron, copper, manganese, molybdenum, chlorine) and beneficial elements ( Such as silicon, selenium, chromium, etc.), except for a small amount of elemental fertilizers, most of the nutrients are often in the form of salts, and these salts are collectively referred to as chemical fertilizers. [0003] Fertilizer itself has acidity and alkalinity, and different metal ions are combined with different acid radicals. Because of the different combinations of strong alkalinity and weak alkalinity of metal ions and strong acidity an...
