Embodiment 1

[0036] A kind of preparation method of the organic mineral fertilizer containing PAL bioremediation preparation, carries out successively according to following steps:

[0037] Step 1: take the lignite and air-dry it, crush and sieve it so that the water content of the lignite is ≤20%, take plant ash powder, fish meal and air-dried lignite and mix evenly, add water to the mixed powder and water in a ratio of 1:10, put Boil in a pot for 15 to 20 minutes, and get the original solution A and residue A after cooling;

[0038] Step 2: Air-dry the pig manure to make the water content ≤ 40%, crush and sieve the PAL porous composite material, stir and mix with earthworm, crop straw, wine tank, vinegar tank, egg shell, residue A and pig manure evenly, Add probiotic strains and stock solution A while stirring to mix all materials evenly, and prepare the mixture for fermentation under certain conditions. The conditions for the fermentation are that the fermentation start temperature is ...

Embodiment 2

[0047] Compared with Example 1, the conditions for the fermentation in step 2 in this example are that the fermentation start temperature is 17°C, the fermentation temperature is controlled at 60°C, the fermentation time is 8 days, and the pressure in step c) is 15t, less The particle size of the balls was 10mm, and the sintering temperature was 750°C. The concentration of the dilute acid solution in step d) is 2.5%, placed at a temperature of 70°C for 2.5 hours, and dried at a temperature of 120°C. The temperature in step e) is 100°C. The particle size of the PAL porous composite material is 1000mm, the porosity is 50%, the pore diameter is 400nm, and the specific surface area is 500㎡ / g. The rest of the process and equipment used are the same as those in Embodiment 1, and will not be described again.

Embodiment 3

[0049] Compared with Example 1, the conditions for the fermentation in step 2 in this example are that the fermentation start temperature is 20°C, the fermentation temperature is controlled at 65°C, the fermentation time is 10 days, and the pressure in step c) is 20t, less The particle size of the balls is 15mm, and the sintering temperature is 1000°C. The concentration of the dilute acid solution in step d) is 5%, placed at a temperature of 90° C. for 5 hours, and dried at a temperature of 150° C. The temperature in step e) is 150°C. The particle size of the PAL porous composite material is 2000mm, the porosity is 80%, the pore diameter is 800nm, and the specific surface area is 1000㎡ / g. The rest of the process and equipment used are the same as those in Embodiment 1, and will not be described again.

Abstract

The invention relates to a preparation method of an organic functional fertilizer containing a PAL biological repairing preparation, and belongs to the technical field of fertilizers. The preparation method comprises the following steps of step I, taking lignite, drying the taken lignite, crushing the dried lignite, screening the crushed lignite, taking plant ash powder and fish meal, uniformly mixing the taken plant ash powder and the taken fish meal with the lignite so as to obtain powder, adding water to the powder in the proportion of the power to water being 1 to 10, putting the water and the powder in a pot for boiling over for 15-20 minutes, and then performing cooling so as to obtain a stock solution A and residues A; and step II, drying pig manure, taking a PAL porous composite, crushing the taken PAL porous composite, screening the crushed PAL porous composite, uniformly mixing the screened PAL porous composite with lumbricus, crop straw, vinasse, vinegar dregs, eggshells, the residues A and the pig manure, adding probiotics and the stock solution A during stirring, so that all of the materials are uniformly mixed to form a mixture, fermenting the prepared mixture under a certain condition, extruding the mixture fermented in the step II, performing granulation and performing packaging, so as to obtain the organic functional fertilizer. Adsorptivity combination can be formed, relative-polymeric structure beneficial ingredients are easy to absorb by crops, and have favorable release control effects, and the crops can be adjusted to uniformly grow, so that the quality of the crops is improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a preparation method of an organic functional fertilizer containing a PAL bioremediation preparation. Background technique [0002] 1. Current status of chemical fertilizer use in China [0003] China is a country with a large population. Since ancient times, natural farming has been mainly used as a labor method. Among them, food production occupies an important position in the development of agricultural production. Fertilization can not only improve soil fertility, but also an important measure to increase crop yield per unit area. Fertilizer is the most basic and most important material input in agricultural production. According to the statistics of the Food and Agriculture Organization of the United Nations (FAO), chemical fertilizers account for about 40% to 60% of the total increase in crop production. China can feed 22% of the world's population with ...
