Abstract
The invention relates to soil conditioner which can improve the acidity of the soil; while the soil conditioner improves the acidity of the soil, the soil conditioner can provide a plurality of nutrient elements for the soil to guarantee the major, medium and microelements for the growth of the plants; the soil conditioner and the preparation method include that the soil conditioner is prepared through the steps as the followings: calcium magnesium phosphate, blast furnace slag and humic acid are grinded respectively; and then the grinding materials are mixed evenly, granulated and dried sequentially according to certain weight ratio; the soil conditioner is composed of 3%-4% of phosphoric anhydride, 20%-30% of silicon dioxide, 3%-5% of magnesia and 8%-10% of organic matter; when the soil conditioner in the invention is adopted, not only the acidity of the soil is improved, but also the content of the soil nutrient is increased.
Description
Technical field
The present invention relates to a kind of soil conditioner and preparation method thereof.
Background technology
At present, in crop planting,, and influenced the normal growth of crop, results often because the acid or alkalescence of soil is excessive.Make crop failure, bad.Aspect the soil ph conditioning of near section time, there has been product obtaining certain progress aspect the soil acidity improvement, as the patent No.: the mud that the utilization of mentioning in 200410008771.1 " a kind of methods of utilizing paper waste to handle the improving sludge acid soil " contains xylogen is material realize the improving the soil method reality relatively of environment, realize easily, but when improving the soil, provide crop other compositions if can continue mutually in necessary for growth, just can reach the effect of getting twice the result with half the effort, when making soil acidity obtain adjusting, increase trace element in the part, help the plant growth demand.
Summary of the invention
First purpose of the present invention provides a kind of soil conditioner big or middle, trace element that contains.
Second purpose of the present invention provides the preparation method of this soil conditioner.
For first purpose that realizes inventing, the soil conditioner that is provided, comprise with fused(calcium magnesium)phosphate, blast furnace slag, humic acid, behind separated pulverizing, according to ratio of weight and number is the ratio of fused(calcium magnesium)phosphate, blast furnace slag, humic acid=20-24: 63-68: 10-14, pass through uniform mixing, granulation, oven dry successively, make the soil conditioner that contains 3%-4% Vanadium Pentoxide in FLAKES, 20%-30% silicon-dioxide, 3%-5% magnesium oxide and 8%-10% organic matter
Be to increase soil conditioner particulate intensity, weight part also is provided is 1 in the proportioning raw materials of the soil conditioner that is provided, carboxymethyl cellulose through pulverizing.
For second purpose that realizes inventing, the preparation method of the soil conditioner that is provided comprises the steps: successively
A, pulverizing: respectively fused(calcium magnesium)phosphate, blast furnace slag, humic acid are crushed to 150 orders-200 order or respectively fused(calcium magnesium)phosphate, blast furnace slag, humic acid and carboxymethyl cellulose are crushed to 150 orders-200 order;
B, mixing: according to ratio of weight and number is fused(calcium magnesium)phosphate, blast furnace slag, humic acid uniform mixing or fused(calcium magnesium)phosphate, blast furnace slag, humic acid: carboxymethyl cellulose=20-24: 63-68: 10-1 after the ratio of fused(calcium magnesium)phosphate, blast furnace slag, humic acid=20-24: 63-68: 10-14 will be pulverized: the fused(calcium magnesium)phosphate after 1 ratio will be pulverized, blast furnace slag, humic acid and carboxymethyl cellulose uniform mixing form the powder that is mixed;
C, granulation: the powder that will be mixed is earlier sent into revolving drum granulator, it is the 0.5mm-1mm master batch that the powder formation granularity that is mixed above 50% is arranged in revolving drum granulator, again this master batch and the remaining powder that is mixed are sent into the one-level granulating disc that has sprinkler head, water evenly is sprayed on master batch and the remaining powder that is mixed, forming granularity is the particle of 1.5mm-5.0mm, these particles improve its hardness through second granulating disc, form reinforcing particle;
D, first drying: with the reinforcing particle temperature is 150 ℃-230 ℃ rotary drum dryer oven dry 2 minutes-3 minutes, and making the water content of reinforcing particle is 18%-25%, makes work in-process;
E, screening: work in-process are sieved for twice, the screen-aperture that sieves for the first time is 2mm, filter out granularity and deliver to the B step less than the small-particle of 2mm, the screen-aperture that sieves for the second time is 4.2mm, filter out granularity and deliver to the B step after crushed greater than the macrobead of 4.2mm, remaining particle is the screening particle;
F, secondary drying: will screening particle, to send into temperature be 230 ℃-300 ℃ sulfuration bed, dried 20 seconds-60 seconds, makes water content and be not higher than 3% soil conditioner.
Soil conditioner provided by the present invention not only contains the organic matter of improving the soil, also contains needed macroelement Vanadium Pentoxide in FLAKES, moderate-element silicon-dioxide and micro-magnesium oxide in the growing process, has reduced planting cost effectively.Use soil conditioner provided by the present invention, not only can improve the soil, can also make soil nutrient abundant.Adopted twice oven dry among the preparation method, compared, improved production efficiency with traditional first drying.
Embodiment
A, pulverizing: respectively fused(calcium magnesium)phosphate, blast furnace slag, humic acid and carboxymethyl cellulose are crushed to 150 orders-200 order; Fused(calcium magnesium)phosphate wherein derives from Yunnan Province, Guizhou Province or Sichuan Province, comprises in its composition: Vanadium Pentoxide in FLAKES 〉=18%, magnesium oxide 〉=12%, silicon-dioxide 〉=20%, blast furnace slag derive from each big steelworks of the whole nation, and humic acid derives from Xinjiang;
B, mixing: according to ratio of weight and number is fused(calcium magnesium)phosphate, blast furnace slag, humic acid: carboxymethyl cellulose=20-24: 63-68: 10-1: the fused(calcium magnesium)phosphate after 1 ratio will be pulverized, blast furnace slag, humic acid, carboxymethyl cellulose uniform mixing form the powder that is mixed;
