Abstract

The present invention belongs to a special vegetable compound fertilizer. The special vegetable compound fertilizer comprises humic acid ammonium or nitro humic acid, effective nitrogen, effective phosphorus, effective potassium, effective calcium, effective magnesium, effective zinc, etc., and the synthesized raw materials are urea, diammonium phosphate, potassium sulfate, ordinary superphosphate, zinc sulfate, adelite phosphoric acid, etc. The synthesized raw materials are proportionally and orderly put in a mechanical stirring device to stir to form finished products. The present invention has the advantages of reasonable proportioning of fertilizer elements, organic and inorganic synthesis, general fertilizer supply, long residual period, no accumulation of soil ion under the condition of water shortage, small side effect and high yield.

Description

Compound fertilizer specially for solanaceae fruit vegetables and production method

The invention belongs to the agricultural fertilizer technical field, be specially adapted to the solanaceous vegetables fertilising and use.

At present, both at home and abroad the common fertilizer special for vegetable that adopts is to survey development and production on the basis that soil joins basically, dedicated fertilizer as plant growth, this fertilizer only considers that the absorbed dose of a large amount of and little heavy element of crop and soil feed rate are important parameter designing, its advantage is: overcome the blindness that local habits fertilization method fertilizer uses, substantially guaranteed the required nitrogen of different times crop, phosphorus, the composition of potassium and trace element, its weak point is fertilizer can not be carried out organic and inorganic combination in fertile production, and this polynary fertilizer only is applicable to the needs that field crop or outdoor vegetable produce mostly, can not use as the vegetables chemical fertilizer specially.

In order to overcome the deficiency of above polynary fertilizer, purpose of the present invention provides a kind of solanaceous vegetables special-purpose fertile, in existing fertilizer, add an amount of humic acids, adopt composite fertilizer special organic and that inorganic fertilizer combines, overcome effectively that a large amount of use chemically growns are paid element, fruit urges phlogiston etc. to cause toxic side effect, gather in advance thereby reach not use under the chemical agent situation, increase output, produce nontoxic vegetable based food.

The contained element and the weight percent of compound fertilizer specially for solanaceae fruit vegetables of the present invention are as follows:

Ammonium humate or nitro humic acid 5～8%

Available nitrogen (N) 13～16%

Available phosphorus (P ₂O ₅) 5～8%

Effective potassium (K ₂O) 11～14%

Effective calcium (CaO) 8～9%

Effective magnesium (MgO) 2～4%

Effective zinc (ZnO) 0.1～0.2%

Used synthesis material formula rate is as follows:

Ammonium humate or nitro humic acid, activated humic acid reach 25～35% 5～8%

Urea N:46% 27～35%

Diammonium phosphate P ₂O ₅: 46%

N:18％ 3～10％

Vitriolate of tartar K ₂O50% 22～28%

Calcium superphosphate (solidifying agent) P ₂O ₅: 14% 25～30%

CaO:25％

MgO:25％

Zinc sulfate (water) ZnO:35% 0.3～0.6%

Fused(calcium magnesium)phosphate (dispersion agent) P ₂O ₅: 12% 8～18%

The preparation process of composite fertilizer:

With above raw material respectively in proportion, put into mechanical stirring device (disc type feeding machine) by following sequencing and stir at normal temperatures and pressures, be packaged as finished product at last:

1, urea

2, ammonium humate or nitro humic acid

3, diammonium phosphate

4, vitriolate of tartar

5, calcium superphosphate

6, spray the aqueous solution of zinc sulfate

7, fused(calcium magnesium)phosphate

8, packing

The embodiment of the invention:

The effective content of composite fertilizer (by weight):

Nitrogen 14%

Vanadium Pentoxide in FLAKES (P ₂O ₅) 5%

Potassium oxide (K ₂O) 13%

Zinc oxide (ZnO) 0.1%

Magnesium oxide 3%

The basis required weight of synthetic fertilizer effective content (Kg)

Urea (N:46%) 300.43

Diammonium phosphate (N:18%) 10.00

(P ₂O ₅:46％)

Calcium superphosphate (P ₂O ₅: 14%) 350.00

Vitriolate of tartar (K ₂O:50%) 260.00

Ammonium humate (K ₂O:50%) 71.00

Zinc sulfate (ZnO:35%) 71.00

Above raw material is dosed stirring sequentially, is finished product at last.
