Application: An efficient high analysis compound fertilizer. Suitable as a seeding fertilizer, base fertilizer or for top dressing.
The appearance of heavy superphosphate is similar to that of
ordinary calcium, usually grayish white, dark gray or grayish
black. The granulated fertilizer is usually a **5 granule with a
bulk density of about ***0 kg / m. The main component of heavy
superphosphate is monocalcium phosphate monohydrate. Since the raw
material phosphoric acid and phosphate rock contain impurities, the
product also contains a small amount of other components. The
general grade of international heavy-duty calcium phosphate is
N-P2o*-K2O: *****0. China's industry standard for heavy
superphosphate products, HG*****9l, stipulates that: effective P2O5
≥ *8% in heavy superphosphate is qualified, and P2 ≥ *6% is
superior.
Granular heavy superphosphate can be used directly or as a
phosphorus raw material for admixing fertilizers. Powdered granular
super-superphosphate can be used as an intermediate product and
other nitrogen or potassium-based basic fertilizers or trace
element raw materials to be processed into a compound fertilizer
containing various nutrients to meet the needs of different soils
and crops.
The advantage of heavy superphosphate is the high concentration of
nutrients, and most of them are water-soluble phosphorus, which
saves packaging and transportation costs and reduces field costs.
Therefore, the construction of a heavy superphosphate device in the
phosphate rock producing area is more economical and reasonable.
The other advantage of the product is that the P2O5 contained in
the product is directly converted from low-cost phosphate rock.
That is, more effective P2O5 can be obtained by producing a certain
amount of phosphoric acid to produce heavy superphosphate than to
produce ammonium phosphate.
Heavy calcium has obvious yield-increasing effects on most crops
such as wheat, rice, soybean, corn, talented, etc., such as: can
promote early maturity of rice, increase tillering, vigorous
growth, thick stems, early heading, and reduce openness; Promote
the growth and early maturity of maize seedlings, and promote the
plant height, ear weight, grain number per spike, and ****-grain
weight; promote wheat growth in the flood season, robust plants,
promote tillering, and have obvious yield-increasing effects; Not
only does it maintain good nutrients in the soil, it also enhances
root development, increases root numbers, and increases nitrogen
supply. Yes, 1, centralized use, 2, mixed with organic fertilizer
application, 3, layered application, 4, root external
application.
