preparation example Construction

[0037] (1) Preparation of nitro humic acid crude material: first make concentrated nitric acid into 25%-30% nitric acid solution, then add weathered coal (humic acid content 40%-50% according to the mass ratio of coal acid ratio 0.5-0.8) ), after stirring for 30-40min, obtain the nitrohumic acid crude material;

[0038] (2) Preparation of nitrohumic acid calcium magnesium: 100 parts (dry basis) of the nitrohumic acid crude material prepared above and 50 parts (dry basis) of calcined dolomite crushed to 60 meshes, while adding the former The water with a total weight of 70%-80% is uniformly stirred by a mixer and then reacted at 90° C. for 4 hours to obtain calcium magnesium nitrohumate after aging.

[0039] The sugar residue is the waste residue produced after starch saccharification in the production process of monosodium glutamate; the dry cake is rapeseed cake or peanut cake, which is cake-shaped residue after oil extraction from rapeseed or peanut seeds; the pig manure bas...

Embodiment 1-5

[0057] Embodiment 1-5 relates to a kind of high fertilizer efficiency organic fertilizer, and its preparation method is as follows:

[0058] The calcium magnesium nitrohumate, sugar residue, dry cake and pig manure-based vermicompost are fully mixed in proportion to obtain a mixed material system. Grinding the mixed material system to obtain a mixed material system with a particle size of 0.25 mm, then adding binder and water to the mixed material system, mixing to make a honeycomb coal shape with a circular cross section, and then heating at 50°C Dried, that is.

[0059] Among them, the addition amount of calcium magnesium nitrohumate, sugar slag, dry cake, pig manure-based vermicompost and binder are shown in Table 1;

Embodiment 6

[0066] The only difference between this embodiment and Example 3 is that, in this embodiment, the organic fertilizer is prepared according to the following steps:

[0067] Fully mix calcium magnesium nitrohumate, sugar residue, dry cake, pig manure-based vermicompost and binder in proportion to obtain a mixed material system, crush and grind the mixed material system to obtain a mixed material with a particle size of 0.25mm system, and then dried at 50°C to obtain powdered organic fertilizer.

Abstract

The invention relates to the field of organic fertilizers, in particular to a high-fertilizer-efficiency organic fertilizerand a preparation method and application thereof. Based on the total mass ofthe organic fertilizer, the organic fertilizer comprises the following raw materials in parts by weight: 13 to 22 parts of nitro humic acid calcium magnesium; 15 to 21 parts by weight of sugar residue; 18 to 33 parts by weight of dried cake; 35 to 45 parts by weight of pig manure-based wormcast. Nitro humic acid calcium magnesium, sugar residues, dried cakes and pig manure-based wormcast are mixedaccording to specific compatibility so that the content of nitrogen, calcium and magnesium nutrient elements in the obtained high-fertilizer-efficiency organic fertilizer is higher than that of a traditional organic fertilizer, the proportion is more reasonable, the citrus growth requirement can be met, and citrus growth is facilitated.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a high-efficiency organic fertilizer and its preparation method and application. Background technique [0002] Citrus is the most important economic tree species in southern my country. Because citrus fruits are sweet, delicious and nutritious, they can not only be eaten fresh, but also be processed into fruit juice, jam, canned food, fruit wine, etc.; essential oils, pectin and citric acid extracted from citrus are widely used in food processing and medicine and other industries. Therefore, high-quality and high-yield citrus plays an important role in the construction of new countryside. [0003] Fertilizer is a major invention and creation of plant nutrition in modern agriculture, and has made outstanding contributions to the promotion of agricultural modernization and high-quality agricultural products. Scientific and rational application of chemical fertilizers can not o...
