Organic fertilizer and its production process

Abstract

The present invention belongs to the field of organic fertilizer producing technology. Organic fertilizer is produced with fruit slag, assistant, complex enzyme and water and the material may contain some nitrogen fertilizer. The production process includes producing composite enzyme preparation containing cellulase, hemicellulase and pectase with selected aerobic bacteria strain; mixing fruit slag, assistant, complex enzyme and water in certain proportion; and fermentation inside a sealed fermenting bin via temperature raising stage, high temperature stage, temperature lowering stage and fertilizer maintaining stage to produce the organic fertilizer. During the production, lime is used to neutralize acid fruit slag and increase calcium in the fertilizer, and artificial semi-earth compost fermentation technique is utilized to lower production cost.

Description

1. Technical field:

[0001] The invention belongs to the technical field of agricultural chemical fertilizers, especially the technical field of organic fertilizers. 2. Background technology:

[0002] Pomace is the residue after apple juice is squeezed. Due to the lack of timely and effective treatment for a long time, fruit flies breed and odor is emitted, which seriously pollutes the surrounding environment. Domestic research on apple waste began in the late 1980s, mainly to study the production of feed (pigs, cattle, etc.) from apple waste, and then apply livestock manure to the soil to achieve ecological cycle balance. However, apple waste cannot be directly made into feed. It must be mixed with corn and other grains to make feed that pigs and cattle like to eat, which consumes a lot of grain. 3. Contents of the invention:

[0003] Pomace is the waste after concentrated fruit juice, which can generally account for 87.5% of the weight of processed apples, with a solid c...

Examples

Embodiment 1

[0040] Embodiment 1, a kind of organic fertilizer, take pomace as base material, contain 30 parts of pomace, 10 parts of auxiliary agent, 0.1 part of compound enzyme, 59.9 parts of water by weight.

[0041] The additive is obtained by mixing lime and slag, contains 15-20% of Ca, and contains mineral elements such as Fe, Mg, Si, etc., and is mainly used to neutralize organic acids in pomace, and react with organic acids to form organic acid calcium. And the acidity and alkalinity of pomace can be adjusted to the pH value required by compound enzyme fermentation. At the same time, crushing the additives to 20-80 meshes as a filler can also provide sufficient space for the fermentation of pomace, reduce the negative impact of pomace viscosity, and ensure that pomace can be fully fermented under aerobic conditions. The organic acid calcium formed after fermentation can provide sufficient calcium sources for crops and prevent various calcium deficiency physiological diseases such a...

Embodiment 2

[0078] Embodiment 2, an organic fertilizer, with pomace as a base material, contains 44 parts of pomace, 4 parts of auxiliary agent, 0.07 part of compound enzyme, and 51.93 parts of water by weight.

Embodiment 3

[0079] Embodiment 3, a kind of organic fertilizer, take pomace as base material, contain 50 parts of pomace, 5.98 parts of auxiliary agent, 0.02 part of compound enzyme, 44 parts of water by weight.
