Set forth its advantage and application below in conjunction with content of the present invention: functional fertilizer of the present invention is made up of A, B, three groups of potassium phosphate salts of C.Potassium phosphate salt is not only a kind of phosphorus, potassium binary compound fertilizer of high-quality, is again typical pH value buffer system simultaneously, is molten stablizer and the sustained release dosage of depositing dioxide peroxide; Be a kind of phosphorus, potassium binary compound fertilizer that contains high density, high-quality, can for a long time, stably slowly discharge the dioxide peroxide active substance of sterilization and disinfestation simultaneously again.
A group potassium phosphate salt is made up of the dipotassium hydrogen phosphate that contains three crystal water and chlorite, and chlorite is the parent that generates dioxide peroxide, and dipotassium hydrogen phosphate is not only phosphorus, potassium binary compound fertilizer fertilizer, still chloritic stablizer.
Chlorite is Textone or potassium chlorite, for avoiding can be farm crop again potassium element is provided because there is the risk that causes the soil salinization in sodium ion, therefore preferred potassium chlorite.
B group potassium phosphate salt is made up of the dipotassium hydrogen phosphate that contains three crystal water and chlorated fulminuric acid compounds, the chlorated fulminuric acid compounds is hypochlorous donor, hypochlorous acid is the exciting agent that chlorite generates dioxide peroxide, dipotassium hydrogen phosphate is not only phosphorus, potassium two-nutrient compound fertilizer, or the stablizer of chlorated fulminuric acid salt compounds.
The chlorated fulminuric acid salt compounds is mainly Surchlor GR 60, sodium trichloro-isocyanurate.Wherein Surchlor GR 60 is soluble in water, and sodium trichloro-isocyanurate is water-soluble relatively poor, therefore preferred Surchlor GR 60.
C group potassium phosphate salt is made up of the dipotassium hydrogen phosphate that contains three crystal water and potassium primary phosphate, be one group of pH value, 6.5 to 7.0 phosphate buffers, it is the main body of functional potassium phosphate salt fertilizer, be the pH value conditioning agent of A, two groups of alkaline phosphatase sylvite of B, also moltenly deposit, carrier and the buffer system of slowly-releasing chlorine dioxide.
Medicament as sterilization and disinfestation on the agricultural, its pH value is more suitable with slightly acidic or neutrality, can not cause the chemistry injury to farm crop, with the dipotassium hydrogen phosphate of three crystal water and the ratio prescription of potassium primary phosphate 1: 1～3, control its pH value in 6.5～7.0 main bodys as functional potassium phosphate salt fertilizer, the parent-chlorite that adds chlorine dioxide generating agent more namely becomes the phosphoric acid potash fertilizer that can discharge Fungicidal active substance.
If only use weakly acidic phosphoric acid salt as chloritic souring agent, because of its H that obtains
+Concentration therefore only have the chlorite of small part to be generated dioxide peroxide by acidifying, and most chlorite fails to be utilized very little.If make most of chlorite acidifying generate dioxide peroxide, the pH value must be regulated≤3.0, high like this acidity can cause serious injury farm crop.
Hypochlorous acid, hypochlorite can promote chlorite to generate dioxide peroxide, but when hypochlorous acid solution or hypochlorite solutions interact with the chlorite solution, the potential of hydrogen difference of reaction medium, also difference of the reaction product that produces.
