Abstract
The present invention relates to a furnace slag slow-release compound fertilizer carrier, which comprises, by weight, 60-80 parts of blast furnace slag, 10-20 parts of wood powder, and 7-8 parts of limestone. The furnace slag slow-release compound fertilizer carrier preparation method comprises: adding 60-80 parts by weight of blast furnace slag and 7-8 parts by weight of limestone to a crusher to crush into powder; adding the obtained powder and 10-20 parts by weight of wood powder to water, stirring, and adding the obtained mixture to a granulator to granulate; placing the granulated particles to a kiln to heat to achieve a temperature of 200-400 DEG C, and carrying out ventilation oxidation; and cooling the heated particles to a room temperature to obtain the furnace slag slow-release compound fertilizer carrier. According to the present invention, characteristics of simple process, short production cycle, strong absorption ability of particles and soil pH value improvement are provided.
Description
Technical field
The present invention relates to a kind of fertilizer, particularly a kind of slag slow-release compound fertilizer carrier and preparation method thereof.
Background technology
CN102850110A as open in Chinese patent, disclose a kind of carrier of wetting ability slow-release fertilizer, comprised 0.5～2 part of 10～60 parts of 0～100 part of 10～90 parts of wood powders, starch, vinylformic acid or derivatives thereofs, polymerisation catalysts, 1～20 part of the chainextender of weight part.The invention also discloses slow-release fertilizer of this carrier of application and preparation method thereof.This preparation method comprises: in reaction vessel, add in proportion wood powder, starch, additive, catalyzer and chainextender, by 0.01～0.2 times of added raw material cumulative volume, add water, at 40～90 ℃ of temperature, stir 0.5～4h, obtain gel carrier; 2) by step 1) to put into mass concentration be that the aqueous solution of 1～90% chemical fertilizer soaks 1～10 day to gained carrier, obtains product.
But above-mentioned employing industrial chemicals hard degradation has toxicity to soil simultaneously, the higher spread that is not suitable for of its raw materials cost is used.
Summary of the invention
In order to solve existing employing industrial chemicals hard degradation, soil is had to toxicity, the higher shortcoming that is not suitable for spread use of its raw materials cost, the invention provides a kind of slag slow-release compound fertilizer carrier and preparation method thereof simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: a kind of slag slow-release compound fertilizer carrier, its component, in weight fraction, comprises 60-80 part blast furnace slag, 10-20 part wood powder, 7-8 part Wingdale.
A preparation method for slag slow-release compound fertilizer carrier, preparation process is as follows:
(1) 60-80 part blast furnace slag and 7-8 part Wingdale are added and in pulverizer, be ground into powder;
(2) after being added to the water to stirring, the above-mentioned powder making and 10-20 part wood powder add granulator granulation;
(3) particle of making is put into kiln and be heated to 200-400 ℃ and the oxidation of ventilating;
(4) particle after heating is cooled to room temperature and had both obtained slag slow-release compound fertilizer carrier.
The invention has the beneficial effects as follows: technique is simple, with short production cycle, particle high adsorption capacity can improve P in soil H simultaneously.
