Easy-to-absorb and pollution-free fertilizer prepared from pig manure and preparation method of fertilizer

Abstract

The invention discloses easy-to-absorb and pollution-free fertilizer prepared from pig manure and a preparation method of the fertilizer. The fertilizer is liquid fertilizer and contains, in percentage by mass, 10%-15% of water-soluble amino acid, 7%-8% of water-soluble polysaccharide, 3%-5% of free nitrogen, 2%-2.8% of free phosphorus, 0.5%-0.9% of free potassium, rhodomicrobium vannielii with mass concentration being 1*10<7> cfu / g-2*10<8> cfu / g, desulfotomaculum nigrificans with mass concentration being 3*10<6> cfu / g-1*10<8> cfu / g, phosphorus-dissolving bacillus megatherium with mass concentration being 3*10<6> cfu / g-1*10<8> cfu / g and nocardia with mass concentration being 6*10<6> cfu / g-2*10<8> cfu / g. The fertilizer is high in recovery rate, good in plant absorptivity, capable of utilizing waste, reasonable in nutrition proportion and free of manure odor.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a kind of easy-absorbable pollution-free fertilizer for treating pig manure and a manufacturing method thereof. Background technique [0002] Pig manure contains only 15% organic matter, of which protein accounts for about 10% of the total weight of manure. Pig manure is finer in texture and contains more organic matter and nitrogen, phosphorus and potassium nutrients. However, pig manure treatment is a key environmental protection technology, otherwise it will cause environmental pollution. However, in the prior art, pig manure is generally retting and used directly as fertilizer for planting and planting. The manure smell is obvious and the plant absorption rate is low, mainly because the organic matter in the pig manure is untreated, it is difficult for plants to absorb, and nutrients are released at the same time. At the same time, because a large amount of organic matte...

Problems solved by technology

However, in the prior art, pig manure is generally retting and used directly as fertilizer for planting and planting. The manure smell is obvious and the plant absorption rate is low, mainly because the organic matter in the pig manure is untreated, it is difficult for plants to absorb, and nutrients are released at the same time. At the same time, because a large amount of organic matter still exists, it will be decomposed by microorganisms in the land to produce environmentally harmful gas-ammonia, and the smell of manure is also a major factor restricting this fertilizer.
