Problems solved by technology

[0004] The main method of controlling soil acidification disasters at home and abroad is lime spreading, but combining the positive and negative effects of lime spreading, lime spreading is effective in a short period of time in some places, but has no effect in a long period of time, and has no effect in most places

Embodiment 1

[0042] Embodiment 1: a kind of high-efficiency alkaline organic phosphorus compound fertilizer that is used for acidifying soil, first produces 10000g alkaline organic phosphorus fertilizer, and its manufacture method is: (1) choose 8000g to process organic matter through high-temperature aerobic fermentation, and it contains humic acid Fulvic acid, polysaccharides, amino acids, enzymes, microorganisms and other organic matter, with soil flavor, no odor, 1000g of alkali metal salt (potassium sulfate), 1000g of phosphate rock powder, mix and stir until the pH value is 8, and the water content is 50%. C / N is 1 / 30;

[0043] (2) At a temperature of 75°C, after aerobic fermentation treatment, the cycle is 30 days,

[0044] (3) The fermented material is pulverized, followed by coarse and fine separation, and the coarse particles are vibrated and ground to produce alkaline organic phosphate fertilizer;

[0045] Reproduce 10000g high-efficiency alkaline organic phosphorus compound fe...

Embodiment 2

[0046] Embodiment 2: (1) at first produce 10000g alkaline organic phosphate fertilizer, choose 9000g grass coal, peat, lignite, the humic acid class organic matter that forms after activation treatment, 1000g calcium magnesium phosphate fertilizer is stirred and mixed, fully adsorbed each other, Dissolve until PH value 7-9, moisture 15-30%,

[0047] (2) aging for 25 hours,

[0048] (3) crushing, coarse and fine separation, coarse particles through vibrating mill 60 order fine powder, produce alkaline organic phosphate fertilizer;

[0049] Reproduce 10000g high-efficiency alkaline organic phosphorus compound fertilizer, select the alkaline organic phosphorus fertilizer that 7000g above-mentioned method produces and 100g trace element (CuSO 4 , ZnSO 4 , (NH4) 2 MoO 4 , FeSO 4 , MnSO 4 , MgSO 4 、CoCl 3or boric acid each 12.5g) mixed and stirred, then granulated, dried, cooled, sieved, mixed with 2900g of ordinary calcium superphosphate, and output finished product togethe...

Abstract

Disclosed is a high efficiency alkaline organic phosphorus compound fertilizer for acidifying soil, characterized in that it comprises 60-95 mass% of alkaline organic phosphorus fertilizer, 0.1-1 mass% of microelement and 5-39 mass% of fertilizer. The advantages of the invention includes: 1 supplying phosphor element in the soil; 2 the alkaline organic phosphorus fertilizer has high pH value, can damp and regulate pH value of soil and eliminate poisoning of Al3+; 3 highly efficient, and hard to be fixed by soil, acidifying major element urgently needed by the soil plant; 4 hard to be washed out by rain; 5 regulating damping capacity and pH value of the soil, and improving soil aggregate structure.

Description

[0001] Field [0002] The invention belongs to a compound fertilizer, in particular to a high-efficiency alkaline organic phosphorus compound fertilizer for acidifying soil. Background technique [0003] my country's agriculture has continuously applied chemical fertilizers for more than 20 years, especially a large amount of acidic chemical fertilizers. Farmland soil is generally compacted, organic matter is reduced, and soil acidification is significant. The soil pH value in many areas is <5.5, and the soil pH value in some areas is around 4. , Fujian, the amount of chemical fertilizer per unit area ranks first in the country. In many areas, the farmland soil is seriously acidified, and the pH value is between 4 and 5. Experiments have proved that chemical fertilizers lead to soil acidification. One is to apply a small amount of (NH 4 ) 2 SO 4 22kg / ha, the soil pH value dropped from 6 to 3.53, the reason is that NH 4 -N is nitrified in the soil, releasing 2 moles of H ...
