[0017] The fertilizer of the present invention can be applied to the following crops in field experiments, and its use methods and effects are as follows:

[0018]

[0019]

Embodiment 1

[0021] A biological soil conditioner using oyster shells to extract calcium ions from marine organisms, prepared from the following raw materials by weight:

[0022] 6-8 parts of oyster shell, 6-8 parts of fermented fishmeal fertilizer, 1-2 parts of anti-recropping fungus, 1-4 parts of bentonite, 3-4 parts of nitrogen, phosphorus and potassium fertilizer, 0.1-0.5 parts of medium and trace element fertilizer, shell calcium ion 1-4 parts, chitin 1-4 parts, chitosan 1-4 parts.

Embodiment 2

[0024] The above-mentioned preparation process of using oyster shells to extract marine biological calcium ion biofertilizer specifically includes the following steps:

[0025] (1) Raw material pretreatment: After cleaning the oyster shells, perform high-temperature and high-pressure cooking, keeping the pressure at 1.2~1.5MPa, and the temperature at 150℃~200℃, and cooking for 2 hours; the high temperature and high pressure cooking of the oyster shells not only achieves disinfection The purpose of bacteria is to remove harmful substances and release calcium in oyster shells;

[0026] (2) Drying and crushing: drying and crushing the oyster shells obtained in step (1), crushing to 500 meshes to obtain oyster shell powder; extracting shell calcium ions, chitin and chitosan from them.

[0027] (3) Biological fermentation: The oyster shell powder obtained in step (2) is mixed with fermented fish meal fertilizer, anti-recropping fungus, bentonite, shell calcium ion, chitin, and chitosan in...

Abstract

The invention discloses a biological soil conditioner containing marine biological calcium ions extracted from oyster shells and a preparation process of the biological soil conditioner. The biological soil conditioner is prepared from 6-8 parts of oyster shells, 6-8 parts of fermented fish meal fertilizer, 1-2 parts of continuous cropping resistant fungicide, 1-4 parts of bentonite, 3-4 parts of azophoska, 0.1-0.5 part of medium trace element fertilizer, 1-4 parts of shell calcium ions, 1-4 parts of chitin and 1-4 parts of chitosan. The preparation method includes the steps of steam disinfecting, drying, smashing, grinding, screening, mixing, granulating, canning and the like. The biological soil conditioner has the advantages that the biological soil conditioner obtained through the method can sufficiently release nutrients of oyster shells, is suitable for planting, soil repairing, poultry breeding and aquaculture, reaches the aim of supplementing shell ionized calcium, can be easily absorbed by crops, is high in fertilizer efficiency and remarkable in increase effect, and can have disease prevention and sterilization effects, and meanwhile economic benefits are improved.

Description

Technical field [0001] The invention relates to a preparation process of marine biological calcium, in particular to a biological soil conditioner that uses oyster shells to extract marine biological calcium ions and a preparation process thereof. It is suitable for aquaculture and soil restoration functions, and achieves ionized calcium supplementation in shells. The purpose belongs to the field of fertilizer preparation. Background technique [0002] Oyster, also known as oyster, also known as oyster yellow and sea oyster. In the classification of animals, it belongs to the class Pelobranchia, Oysteridae, and the Latin Ostrea. Oysters are shellfish, and there are more than 100 species in the world. There are about 20 species produced along the coast of my country. At present, the artificially cultivated oysters mainly include Oyster oyster, Pacific oyster, Pleurotus ostreatus and Pacific oyster. The main component of the husk is calcium carbonate, which accounts for about 90%...
