Manufacturing method of Albizzia julibrissin straw compound fertilizer

Abstract

The invention relates to a manufacturing method of an Albizzia julibrissin straw compound fertilizer, which comprises the following steps: selecting biogas slurry which normally has produced gas for one month; fermenting, cutting up dry straws, putting into a fermentation tank together with the biogas slurry and potassium dihydrogen phosphate, simultaneously adding Micromonospora and Polyangium cellulosum, uniformly stirring, performing aerobic fermentation, and fermenting for 30 days while the temperature in the fermentation tank is kept at 35-45 DEG C; opening the fermentation tank, adding Aspergillus flavus and urea, uniformly stirring, closing the fermentation tank, performing anaerobic fermentation, keeping the temperature in the fermentation tank at 45-50 DEG C in the first three days, raising the temperature in the fermentation tank to 73 DEG C from the 3<rd> day to the 5 day, and keeping the temperature in the fermentation tank at 40-45 DEG C from the 6 day to the 30 day; and after the temperature in the fermentation tank falls to room temperature, adding boric acid, chromium trichloride, manganese chloride and zinc sulfate, uniformly mixing, bagging, and packaging.

Description

technical field [0001] The invention relates to a method for making fertilizer, in particular to a method for making a compound fertilizer made of Albizia Julibrissin straw. Background technique [0002] Albizia julienne is also known as velvet tree and nocturnal flower. Native to my country and Japan. Deciduous tree with gray bark. Albizia julibrissin in full bloom has even-pinnate compound leaves with opposite leaflets that open during the day and close at night. Calyx and petals yellow-green, filaments pink, pods flat. Wood can be used for furniture. Also called lantana flower. It likes a warm, humid and sunny environment, and has strong adaptability to climate and soil. It should grow in well-drained and fertile soil, but it is also resistant to poor soil and arid climate. However, long-term single application of chemical fertilizers will cause long-term problems such as soil compaction, nutrient imbalance, and poor physical properties, and the production capacity w...

Problems solved by technology

However, long-term single application of chemical fertilizers will cause long-term problems such as soil compaction, nutrient imbalance, and poor physical properties, and the production capacity will drop significantly, and the fertilizer efficiency of organic fertilizers will be slow. Burn directly in the field to avoid affecting the cultivated land; although this treatment method is simple, it seriously damages the beneficial microorganisms in the soil and is not conducive to the growth of crops; in addition, the carbon in the straw accounts for the vast majority, followed by potassium, silicon, Calcium, magnesium, sulfur, phosphorus, the products after incineration mainly include CO 2 , CO, SO 2 , NO 2 and N 2 O, these harmful gases have caused serious environmental pollution after entering the atmosphere; if these straws are composted and returned to the field, they will become rich organic fertilizers to fertilize the soil and improve soil properties; microbial degradation of straw cellulose is through secretion into the cell External free cellulase, which degrades cellulose with hydrolase mechanism and oxidase mechanism; the use of microorganisms can finally decompose cellulose into CO 2 and H 2 0, and a large amount of bacterial protein can be produced through the growth of microorganisms themselves, so the use of microbial methods to treat straw can greatly improve its nutritional value
