Embodiment 1
[0027] Embodiment one: a kind of method utilizing vegetable tail vegetable to prepare solid organic fertilizer comprises the following steps:
[0028] (1) Pretreatment of tail vegetables: cut the cabbage tail vegetables with a water content of 92% into 3-5cm chunks, and perform extrusion dehydration treatment on them, the vegetable cells are destroyed after being squeezed, and the intracellular water is released come out, and then realize solid-liquid separation through centrifugal filtration, and the moisture content of the obtained solid tail vegetable residue is about 50-65%;
[0029] (2) Wetting of sawdust: spray tail vegetable juice on the rice husk with an initial moisture content of about 18-25% (if not enough, replace it with water), so that the final moisture content is controlled at 40-50%;
[0030] (3) Then mix tail vegetable residue, moistened sawdust and chicken manure (moisture content 40-60%) in a mass ratio of 4:3:3, and add 2-5‰ aerobic compost of the total ma...
Embodiment 2
[0034] Embodiment two: a kind of method utilizing vegetable tail dish to prepare solid organic fertilizer comprises the following steps:
[0035] (1) Pretreatment of tail vegetables: cut the cabbage tail vegetables with a water content of 92% into 3-5cm chunks, and perform extrusion dehydration treatment on them, the vegetable cells are destroyed after being squeezed, and the intracellular water is released come out, and then realize solid-liquid separation through centrifugal filtration, and the moisture content of the obtained solid tail vegetable residue is about 50-65%;
[0036] (2) Wetting of rice husk: spray moisture (chlorine-free) to rice husk with an initial moisture content of about 12-16%, so that the final moisture content is controlled at 40-50%;
[0037] (3) Then mix tail vegetable residue, wet rice husk and pig manure (moisture content 40-65%) in a mass ratio of 4:2:4, and add 2-5‰ of the total material mass for aerobic composting fermentation Bacteria, after s...

Abstract
The invention provides a method for producing organic fertilizer from rotten vegetable leaves as well as straw, rice husk, livestock and poultry manure and other agricultural waste. The method comprises steps as follows: (1) the rotten vegetable leaves are cut into blocks which are 2-10 cm long and the straw and other auxiliaries are crushed; (2) the cut rotten vegetable leaves are dehydrated, the dehydrated rotten vegetable leaves with the water content being 50%-65% are obtained, water removed from the rotten vegetable leaves through squeezing is collected and used for wetting straw particles, rice husk and other dry materials; (3) the dehydrated rotten vegetable leaves, the wetted straw or rice husk materials, the livestock and poultry manure and other materials with the adjusted water content are stirred uniformly in a certain proportion; (4) an aerobic composting microbial inoculant is added, aerobic fermentation is performed, and the organic fertilizer is obtained. The rotten vegetable leaves and other agricultural waste can be utilized fully and can be used for producing the organic fertilizer, the purposes of recycling and harmless and circulating treatment of the agricultural waste are achieved, and the method has remarkable effects on improvement of the quality and the yield of crops, reduction of agricultural waste pollution and the like.
Description
technical field [0001] The invention relates to a method for resourceful processing of vegetable tails and prepares solid and liquid organic fertilizers. It specifically involves that the solid residue obtained after dehydration of vegetable tails is mixed with agricultural waste such as straw, rice husk, and livestock and poultry manure with a pre-adjusted moisture content to produce solid organic fertilizers, so that vegetable tails can be fully resourced and harmless. processing. Background technique [0002] With the continuous advancement of my country's "Vegetable Basket Project", the rapid development of the vegetable industry has not only enriched the dishes on the table of ordinary people, but also brought huge economic benefits to vegetable farmers and some rural areas. However, the ensuing problem is how to harmlessly dispose of the ever-increasing vegetable tails. The so-called "tail vegetables" refer to the old vegetable leaves that must be removed when vegeta...
