Abstract
The invention discloses a slow release fertilizer prepared by oyster shell. The technical proposal is that the slow release fertilizer is prepared by oyster shell, the formula (weight percentage) is that: 30 percent to 80 percent ofoyster shell powder, 20 percent to 80 percent of fertilizer and the rest percent of deionized water. When the oyster shell is used to prepare the slow release fertilizer, the oyster shell must be activated at first and is produced into particles of 60 to 200 meshes, and then the particles are produced into the slow release fertilizer with other raw materials.
Description
Technical field
The present invention relates to a kind of Activated Ca made by oyster shell slow release fertilizer of using, belong to the fertilizer science technical field relevant with plant nutrition.
Background technology
China is a large agricultural country, yet in this season 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 country level.
Cause the utilization rate of fertilizer not high loss that major reason is a fertilizer, especially a nitrogen and potash fertilizer.A large amount of losses of fertilizer not only cause enormous economic loss, and environment is caused huge pollution, and Sustainable development is brought very big influence, and human beings'health is constituted very big threat, have caused the great attention of countries in the world.
Use the Activated Ca made by oyster shell slow release fertilizer, can reduce the loss of nutrient in the fertilizer, improve fertilizer efficiency, weaken the pollution of fertilizer soil; And can also reduce the volatilization of moisture, play water retention.Using the Activated Ca made by oyster shell slow release fertilizer, is to be that stratum corneum, prismatic layer, nacreous layer are formed according to the oyster shells physique, and major portion is a prismatic layer, and bladed structure contains a large amount of 2～10 μ m micropores, has very strong adsorptive power.Can be embedded in fertilizer in the micropore, slowly discharge then, the burning seedling that causes because the single fertilization amount is too high can not occur, crop excessive growth, phenomenon such as shape.
Summary of the invention
Technical solution of the present invention is as follows:
Prescription with the Activated Ca made by oyster shell slow release fertilizer is as follows: (weight percent %)
Oyster shell powder 30%～80% chemical fertilizer 20%～80% deionized water surplus
With the Activated Ca made by oyster shell slow release fertilizer is 60～200 order particles after adopting oyster shells activated.
The treatment process steps of oyster shells is as follows:
With oyster shells select, alkali bubble, washing, air-dry back pulverize, and after the screening of 60～200 mesh sieves, delivers to and be heated to 100～150 ℃ in the High Temperature Furnaces Heating Apparatus, is incubated and comes out of the stove after 1 hour, the oyster shell powder after coming out of the stove is after wind drops to room temperature, the threading plastics bag is standby.
Step of preparation process with the Activated Ca made by oyster shell slow release fertilizer is as follows:
(1) oyster shells is handled;
(2) through 200 ℃～250 ℃ activation treatment of high temperature 12 hours;
(3) chemical fertilizer, deionized water are made into the aqueous solution;
(4) the aqueous solution in the absorption of the preparation in (2) (3), leave standstill about 3d, drying and packaging promptly gets product.
Compared with prior art, the present invention has following beneficial effect:
(1) uses the Activated Ca made by oyster shell slow release fertilizer, can reduce the loss of nutrient in the fertilizer, improve fertilizer efficiency, weaken the pollution of fertilizer soil; And can also reduce the volatilization of moisture, play water retention.
(2) oyster shell powder has very strong adsorptive power, can make the present invention reach slow releasing function, and effect is more lasting;
(3) low production cost, and can make full use of resource, oyster shells is turned waste into wealth.
The specific embodiment of the present invention:

Two, as follows with the step of preparation process of Activated Ca made by oyster shell slow release fertilizer:
(1) oyster shells is handled;
(2) get oyster shells 350kg, through 200 ℃～250 ℃ activation treatment of high temperature 12 hours;
(3) chemical fertilizer 350kg, deionized water 300kg are made into the aqueous solution;
(4) the aqueous solution in the absorption of the preparation in (2) (3), leave standstill about 3d, drying and packaging promptly gets product.
Embodiment 3
One, the treatment process steps of oyster shell powder is as follows:
With oyster shells select, alkali bubble, washing, air-dry back pulverize, and after the screening of 100 mesh sieves, delivers to and be heated to 100～150 ℃ in the High Temperature Furnaces Heating Apparatus, is incubated and comes out of the stove after 1 hour, the oyster shell powder after coming out of the stove is after wind drops to room temperature, the threading plastics bag is standby.
Two, as follows with the step of preparation process of Activated Ca made by oyster shell slow release fertilizer:
