Description
Technical field
The present invention relates to a kind of medical stone biological soil improvement agent and preparation method thereof.
Background technology
At present, in crop planting, often excessive uses chemical fertilizer and uses agricultural chemicals, though the crop yield height, having caused crops quality decline, the soil hardens year by year.Not fragrant as the rice wheat, the sweetless and outward appearance deformity of melon and fruit etc., this mainly is the result of the unbalance and pesticide residue of corps nutrient.In order to solve " high yield not high-quality, high-quality not high yield " problem, effective means is to promote the use of soil improvement agent, but all kinds of soil improvement agent effects of releasing are all not obvious at present, and major cause is all to lack can adsorb and degrade chemical fertilizer and the excessive material of pesticide residue in the various soil improvement agents.
Medical stone be a kind of to biological, plant is nontoxic, harmless and have certain bioactive composite minerals rock, medical stone have very strong adsorptive power to harmful several units such as cadmium, mercury, arsenic, lead, so-called absorption is the solid off-bottom effect with porousness, huge surface area, and reaction chemistry, physics takes place.Medical stone is porous, and adsorptive power is very strong, because of its main component is a silicon-dioxide.Because of porousness, the surface is just very big, so remain very strong adsorption, exchange interaction.
Because of above-mentioned functions, medical stone can be stabilized and increased, the physics function of balance soil, so be the soil improvement agent of main raw material more has degrading pesticide residues than other soil improvement agent advantage with medical stone.Use the medical stone biological soil improvement agent can reduce the chemical fertilizer usage quantity, and can improve soil property economical, effectively, accelerate the growth of farm crop, improve the quality of crop, increase output, degraded and absorption of residual She agricultural chemicals guarantee that farm crop are safe to eat.
Summary of the invention
First purpose of the present invention provides a kind of medical stone biological soil improvement agent of chemical fertilizer and pesticide residue that can adsorb and degrade that contains.
Second purpose of the present invention provides the preparation method of this medical stone biological soil improvement agent.
For first purpose that realizes inventing, the medical stone biological soil improvement agent that is provided, comprise with medical stone, humic acids, probiotics and granulation promotor wilkinite, behind separated pulverizing, according to ratio of weight and number is medical stone: the ratio of humic acids: probiotics: wilkinite=60-70: 20-25: 1-2: 10-20, pass through even pulverizing, mixing, granulation, oven dry successively, the medical stone biological soil improvement agent of the probiotics of the be mixed humic acids that makes the medical stone that contains 60%-70%, 20%-25% and 1%-2%.
For increasing medical stone biological soil improvement agent particulate intensity, weight part also being provided in the proportioning raw materials of the medical stone biological soil improvement agent that is provided is 1 carboxymethyl cellulose through pulverizing.
For second purpose that realizes inventing, the preparation method of the medical stone biological soil improvement agent that is provided comprises the steps: successively
A, pulverizing: be that 80 purpose humic acidss and bentonite in powder are broken to 100 orders-120 order with medical stone, granularity or be respectively that 80 purpose humic acidss, wilkinite and carboxymethyl cellulose are crushed to 100 orders-120 order with medical stone, granularity;
B, mixing: according to ratio of weight and number with medical stone: humic acids: wilkinite: carboxymethyl cellulose=60-70: 20-25: 10-20: medical stone, humic acids, wilkinite and carboxymethyl cellulose uniform mixing after 1 ratio is pulverized form powder mix;
