Embodiment 1
[0027] Organic fertilizer composition by weight: organic material (the present embodiment is sawdust) 15%, calcium cyanamide 3% (in the present embodiment, by weight percentage, nitrogen-containing 20%, containing calcium oxide 45%, all the other are Impurities, pH 11.0~12.5), natural zeolite 4%, vegetable waste (by dry weight) 78% (this embodiment is the remaining root and leaf waste in the process of making Chinese cabbage to clean vegetables).
[0028] Choose a relatively flat bare ground as a vegetable waste dump, spread a layer of 15cm thick organic materials, and spread a 40cm thick vegetable waste on the organic materials, and evenly sprinkle calcium cyanamide total amount according to the weight percentage. 50% of the weight, then spread 15cm thick vegetable waste, evenly sprinkle 50% of the total weight of natural zeolite powder by weight percentage, then spread 40cm thick vegetable waste, and evenly sprinkle calcium cyanamide by weight percentage 50% of the total wei...
Embodiment 2～12
[0030] The difference from Example 1 is that the proportioning of raw materials and the height of material stacking are different (Table 1), and the preparation method is the same as in Example 1.

[0032] make up
[0033] In the above table, materials refer to organic materials, vegetable waste refers to the residues in the vegetable production and sales process, calcium cyanide refers to calcium cyanamide, and zeolite refers to natural zeolite powder. Vegetable waste in Examples 2-12 adopts vegetable production base greenhouse or field to produce leafy vegetables (cabbage, scallion, lettuce, rape, celery, potherb mustard, coriander, Chrysanthemum chrysanthemum, spinach, amaranth, etc.), solanaceous fruits (tomato, Eggplant, pepper, etc.), melons (cucumber, pumpkin, wax gourd, zucchini, loofah, bitter gourd, etc.) or legumes (kidney beans, lentils, cowpea, broad beans, etc.) If the vegetable waste is vegetable seedlings, vines, vines, roots, or ste...

Abstract
The invention relates to an organic fertilizer and a treatment technique of wastes in the planting industry, in particular to a vegetable waste organic fertilizer and a preparation method thereof. The preparation method adopts calcium cyanamide, natural zeolite and organic materials as additive materials, and adds the materials in vegetable wastes for piling up and fermentation so as to prepare the organic fertilizer; the method has simple process and low cost, and solves the problems of environmental pollution caused by the vegetable wastes and resource utilization. The components in percentage by weight of the organic fertilizer are: 73 to 84 percent of vegetable wastes, 10 to 20 percent of organic materials, 2 to 4 percent of calcium cyanamide and 3 to 5 percent of natural zeolite. Thepreparation method comprises the following steps: piling up the organic materials, the vegetable wastes, the calcium cyanamide and the natural zeolite in layers in proportion; scattering the organic materials on the outer layer; closing the organic materials by a plastic sheet to carry out fermentation for 7 to 10 days; carrying out mechanical or manual pile turning and then closing the organic materials by the plastic sheet to carry out fermentation for 7 to 10 days again; and obtaining the organic fertilizer after drying the materials in the sun. The vegetable waste organic fertilizer has reasonable formulation, good fertilizer reservation effect and easy implement, and is suitable to be used as fertilizer for producing green vegetables.
Description
technical field [0001] The invention relates to an organic fertilizer and planting industry waste treatment and disposal technology, in particular to a vegetable waste organic fertilizer and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of intensive vegetable production, the area of vegetable bases has become larger and larger. In the process of vegetable production and sales, a large amount of vegetable waste is generated. Especially in greenhouse vegetable production bases, due to the high intensity and high frequency of use of the vegetable field, a large amount of plant residues will be produced during the up and down stubble. In the greenhouse vegetable production area, you will always see vegetables, melons and fruit stems, old leaves, dead leaves, diseased leaves, diseased fruits, diseased plants, etc. piled up everywhere in the village, in front of the shed, on the roadside, and beside the ditch. The main ...
