preparation example Construction

[0033] The invention provides a kind of preparation method of olive pomace organic fertilizer, comprises the following steps:

[0034] (1) adding a nitrogen source substance to the olive pomace, adjusting the C / N ratio to 25:1-30:1 to obtain the olive pomace mixture;

[0035] (2) mixing the microbial starter, wheat bran and corn according to the mass ratio of 1:2.4 to 3:1.6 to 2 to obtain the starter mixture;

[0036] (3) According to the mass ratio of the olive pomace in the olive pomace mixture to the microbial starter in the starter mixture of 100:0.2 to 0.4, the olive pomace mixture is mixed with the starter mixture, and the water content is adjusted to 50 to 55%, Obtain fermentation raw materials;

[0037] (4) Composting and fermenting the fermented raw materials for 20-30 days under an environment of 18-28°C, humidity 10-15%, and oxygen content 8-15%, to obtain olive pomace organic fertilizer;

[0038] There is no time sequence limitation between the step (1) and the s...

Embodiment 1

[0067] Get 1 ton of olive pomace (water content 60%) and mix with urea 17.46kg, diammonium phosphate 22.4kg to obtain olive pomace mixture; get Gymboree fertilizer starter 4kg, wheat bran 9.6kg and corn 6.4kg to mix to obtain a fermentation mixture; The olive pomace mixture is completely mixed with the fermented mixture, and the water content is adjusted to 54 percent to obtain the fermented raw material.

[0068] Pile the fermentation raw materials into a pile with a height of 1.5m, and ferment in an environment of 20°C, humidity 10%, and oxygen content 8%. When the temperature is above 58-60°C, turn the pile once, and keep the water content of the fermentation raw materials at Between 50% and 55%; when the temperature of the fermented raw material heap starts to decrease from the high temperature period and enters the later stage of fermentation, the moisture content of the fermented raw material is controlled below 30% until the end of the fermentation, and a total of 20 day...

Abstract

The invention relates to the field of organic fertilizers, and provides a preparation method of an olive residue organic fertilizer. The method includes the steps: taking olive residue as a main fermenting raw material, adjusting the olive residue to C/N suitable for suitable fermentation before fermentation, enabling fermentation efficiency to be improved, premixing wheat bran, corn and microorganism fermentation agents to facilitate microorganisms in the fermentation agents to breed, mixing the materials according to ratio, and adjusting water content to reach 50-55% to obtain the fermentingraw material; performing compost fermentation on the fermenting raw material in the environments with the temperature of 18-28 DEG C, the humidity of 10-15% and the oxygen content of 8-15% for 20-30days to obtain the olive residue organic fertilizer. Organic matters in the olive residue organic fertilizer prepared by the method account for 68-80% of the total weight of the olive residue organicfertilizer, a total nutrient component of nitrogen, phosphorus and potassium accounts for 5-8.5% of the total weight of the olive residue organic fertilizer, water content is 20-28%, a pH (potential of hydrogen) value is 5.8-8.0, and the organic fertilizer granular. The prepared olive residue organic fertilizer can be applied to improvement of soil.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to an olive pomace organic fertilizer and a preparation method and application thereof. Background technique [0002] Olive [Canarium album (Lour.) Raeusch] is an evergreen tree belonging to the genus Canarium of the olive family (Burseraceae). With the continuous development of the olive processing industry, the production of olive juice, olive fruit wine and olive fruit vinegar and other products prepared from fresh olives is increasing, and the production of olive pomace, a by-product of its processing, is also increasing. The headed area produces about 2,300-3,000 tons of olive pomace, a by-product of olive oil, annually. [0003] China's olive oil and other production companies do not have a good method of processing olive pomace, so that a large amount of olive pomace is discarded, causing certain environmental pollution. Effective utilization of waste and environmental pr...
