Abstract
Disclosed is a fertilizer prepared from oyster shells. A main technical point is to prepare the fertilizer from the oyster shells. The fertilizer includes following components, by weight: 28-78% of oyster shell powder, 30-70% of a chemical fertilizer and the balanced deionized water. Before preparation of the fertilizer from the oyster shells, the oyster shells needs to be activated and to be prepared into granules in 50-180 meshes and then the oyster shells is blended with other raw materials to form the fertilizer.
Description
Technical field
The present invention relates to one oyster shells and make fertilizer, belong to the fertilizer science technical field relevant with plant nutrition.
Background technology
In the utilization ratio of China's chemical fertilizer, nitrogen is about 30% ~ 35%, and phosphorus is about 10% ~ 25%, and potassium is about 35% ~ 50%, well below World Developed Countries level.Utilization rate of fertilizer not high major reason is caused to be the loss of fertilizer, especially nitrogen and potash fertilizer.A large amount of losses of fertilizer not only cause huge financial loss, and cause huge pollution to environment, bring very large impact to Sustainable development, form very large threat, caused the great attention of China to the health of the mankind.
With the fertilizer that oyster is made, the loss of fertilizer nutrient can be reduced, improve fertilizer efficiency, weaken the pollution of fertilizer to soil; The volatilization of moisture can also be reduced, play water retention.The fertilizer that oyster shells is made, be according to oyster shells physique be stratum corneum, prismatic layer, nacreous layer composition, major portion is prismatic layer, and bladed structure has very strong adsorptive power.
Summary of the invention
Technical solution of the present invention is as follows:
Fertilizer formula is made as follows: (weight percent %) with oyster shells
Oyster shell powder 28% ~ 78% chemical fertilizer 30% ~ 70% deionized water surplus
With oyster make fertilizer be adopt oyster shells activated after 50 ~ 180 order particles
The treatment process steps of oyster shells is as follows:
Oyster carried out select, wash, alkali bubble, air-dry rear flour, after 50 ~ 180 mesh sieves screenings, deliver in High Temperature Furnaces Heating Apparatus and be heated to 100 DEG C ~ 160 DEG C, be incubated and come out of the stove after 1 hour, the oyster shell powder after coming out of the stove drops to after normal temperature through wind, and threading plastics bag is for subsequent use.
The processing step making fertilizer with oyster shells is as follows:
(1) oyster shells is processed;
(2) through high temperature 250 DEG C ~ 300 DEG C activation treatment 10 hours;
(3) chemical fertilizer, deionized water are made into the aqueous solution;
(4) preparation in (2) is absorbed the aqueous solution in (3), leave standstill about 3d, namely drying and packaging obtains product.
Compared with existing technology, the present invention has following beneficial effect:
(1) make fertilizer with oyster shells, the loss of the nutrient in fertilizer can be reduced, improve fertilizer efficiency, weaken the pollution of fertilizer to soil; The volatilization of moisture can also be reduced, play water retention.
(2) ostreae testa pulverata has very strong adsorptive power.
(3) Beihai Fisheries Base Guangxi Province has large-scale farming oyster base, and oyster shells is thick on the ground, and production cost is very low, and oyster shells can be made to turn waste into wealth.
The specific embodiment of the present invention:

Two, the processing step of fertilizer is made with oyster shells as follows:
(1) oyster shells is processed;
(2) ostreae testa pulverata 350kg is got through high temperature 250 DEG C ~ 300 DEG C activation treatment 10 hours;
(3) chemical fertilizer 300kg, deionized water 350kg are made into the aqueous solution;
(4) preparation in (2) is absorbed the aqueous solution in (3), leave standstill about 3d, namely drying and packaging obtains product.
Embodiment 2
One, the treatment process steps of oyster shell powder is as follows:
Oyster carried out select, wash, alkali bubble, air-dry rear flour, after 80 mesh sieves screenings, deliver in High Temperature Furnaces Heating Apparatus and be heated to 100 DEG C ~ 160 DEG C, be incubated and come out of the stove after 1 hour, the oyster shell powder after coming out of the stove drops to after normal temperature through wind, and threading plastics bag is for subsequent use.
Two, the processing step of fertilizer is made with oyster shells as follows:
(1) oyster shells is processed;
(2) ostreae testa pulverata 300kg is got through high temperature 250 DEG C ~ 300 DEG C activation treatment 10 hours;
(3) chemical fertilizer 350kg, deionized water 400kg are made into the aqueous solution;
(4) preparation in (2) is absorbed the aqueous solution in (3), leave standstill about 3d, namely drying and packaging obtains product.
Embodiment 3
One, the treatment process steps of oyster shell powder is as follows:
Oyster carried out select, wash, alkali bubble, air-dry rear flour, after 120 mesh sieves screenings, deliver in High Temperature Furnaces Heating Apparatus and be heated to 100 DEG C ~ 160 DEG C, be incubated and come out of the stove after 1 hour, the oyster shell powder after coming out of the stove drops to after normal temperature through wind, and threading plastics bag is for subsequent use.
Two, the processing step of fertilizer is made with oyster shells as follows:
(1) oyster shells is processed;
