Description
Technical field
The present invention relates to a kind of composite mineral fertilizer and preparation method thereof, particularly relate to and a kind ofly have good water-permeable, moisture retention, ventilation property and slow-releasing, and have chessom, suppress composite mineral fertilizer of characteristics such as disease and pest and preparation method thereof.
Background technology
The long-term application of chemical fertilizer easily causes soil compaction, makes chemical fertilizer easily decompose in soil, volatilize simultaneously or loses with current, causes fertilizer efficiency to reduce.Therefore, for a long time, people are exploring always and are prolonging fertilizer efficiency, improve the method for its utilization ratio.The method that has adopted is as at the slow soluble substance of chemical fertilizer granule external parcel, but that this method is proved to be effect is not remarkable, and the cost height, complex process.
In recent years, with the composite fertilizer of some natural mineral, be proved to be and keeping fertilizer efficiency, improve crop yield and reducing aspects such as applying quantity of chemical fertilizer to have effect preferably as preparing carriers.Having reported a kind of as Chinese patent 89105036.1 is the durable composite fertilizer of carrier with the zeolite, and Chinese patent 95100163.9 and Japanese Patent are clear has then reported with the vermiculite to be the composite fertilizer of carrier with 56-59690.
Diatomite is the very abundant nonmetal mineral resources of reserves.Its main component is the natural soft silica by the skeleton formation of deposits of diatom biology, and association has clay mineral, quartz, iron mineral impurity etc.Highly purified diatomite (diatom matter amorphous silica content＞85%) can be used for preparing high value added products such as flocculating aids, functional filler.Yet although China's diatomite resource total amount occupies prostatitis, the world, the high-quality raw ore is very limited.The original soil of most of diatomite ores only is a dioxide-containing silica less than 70% three grades even level Four original soil.Present purification techniques also be difficult to in these, low-grade three, level Four original soil purifies and is therefore to be difficult to highly purified one-level soil be applied in the above-mentioned high value added product industry.
Will in, low-grade diatomite original ore then has the effect of making the best use of everything as composite fertilizer's carrier: diatom shell has very strong adsorptivity, and the clay mineral impurity of association also has very strong ion-exchange and adsorptive power, and this absorption to nutriment in a fertilizer is highly beneficial; Simultaneously, clay mineral, quartz, iron mineral etc. itself are the main component of soil just, and quartz also has good penetration, and they all can not exert an adverse impact to the performance of carrier as submember.That is to say, during as composite fertilizer's carrier, components such as the clay mineral in the diatomite and diatom shell are active principle equally, only need the content of quartz, iron mineral etc. to be controlled within the specific limits by simple the purification, just can with in, low-grade diatomite original ore utilizes as the chemical fertilizer carrier, thereby provide a wide direction for its development and use.
Reported respectively in the Chinese patent 93107871.7 and 94108836.7 from bittern extract potassium and from marine alga, extract iodine after, with the method for diatomite as preparing carriers composite fertilizer.Yet, because the adsorption activity position on diatom shell and clay mineral surface comprises surface hydroxyl, Bronsted acid position and Lewis acid position, often covered at ambient temperature, thereby weakened their adsorptive poweies nutriment in a fertilizer by adsorbed water molecules.Therefore, directly diatomite can be influenced giving full play to of its performance undoubtedly as composite fertilizer's carrier.On the other hand, the described composite fertilizer of above-mentioned two patents does not add antibacterial components, and is unfavorable to pest control and unwanted bacteria.
The content of invention
The object of the present invention is to provide a kind of composite mineral fertilizer, during its uses, low-grade diatomite mineral wealth, be equipped with nitrogenous fertilizer, phosphate fertilizer, potash fertilizer and antibacterial metal salts, and the preparation method that this composite mineral fertilizer is provided.
Technical scheme of the present invention:
A kind of composite mineral fertilizer comprises that diatomite support, antibacterial metal salts are (with Cu
2+Meter), nitrogenous fertilizer, phosphate fertilizer and potash fertilizer, weight ratio is 25-35: 0.1-1: 20-40: 15-35: 10-20.
SiO in the described diatomite support
2Content＞60%, quartz content＜10% (weight).
Described antibacterial metal salts is selected from cupric chloride, cupric nitrate, copper sulfate or the mixture of 2-3 kind in them.
Described nitrogenous fertilizer is selected from urea, carbon ammonium or their mixture.
Described phosphate fertilizer is selected from double superhosphate (coarse whiting), calcium superphosphate (general calcium) or their mixture.
Described potash fertilizer is selected from Repone K, vitriolate of tartar or their mixture.
The performance in tripolite compound provided by the invention Hefei: the pH value is 6-8, and granularity is 3-6mm, and it is shallow brick-red that color is, and bulk density is 5.5-6.5g/ml.
Above the preparation method of described a kind of composite mineral fertilizer, comprise the following steps: successively
(1) ore dressing and purification: select SiO for use
2Content be 55%-75% in, low-grade diatomite original ore is as the raw material of composite fertilizer's carrier, purifies with settling process, removes part iron mineral, quartz and clay mineral impurity, makes SiO in the purification ore deposit
2Content＞60%, quartz content＜10% (weight percent);
