Abstract
The invention relates to a long-acting compound fertilizer for corns. The compound fertilizer is characterized by comprising the following components in parts by weight: 20 to 25 parts of nitrogen, 12 to 18 parts of phosphorus, 8 to 12 parts of potassium, 6 to 8 parts of dicyandiamide, 1 to 3 parts of trace element and 2 to 4 parts of humic acid. The long-acting compound fertilizer for corns has the characteristics of controlled release in an earlier stage, capability of reaching the release peak in a middle stage and continuous supply in a later stage; when the compound fertilizer is applied as a base fertilizer at one time during the seeding of the corns, the farming cost is lowered; the raw materials are extensive, a preparation method is simple, and the expenditure of a farmer for purchasing the fertilizer is reduced.
Description
Technical field
the present invention relates to a kind of farm crop with fertile, particularly relate to a kind of special long-acting corn composite fertilizer, is supplementing existing composite fertilizer kind.
Background technology
fertilizer is very important to crop growth, the grow ratio of needed nitrogen, phosphorus, potassium of Different Crop is different, dissimilar soil supplying nutrient capability is not identical yet, there is certain blindness in most fertilizer formulas, or only from crop demand, do not take into full account the nutrient content in soil.
corn is the crop that needs nitrogen more, needs sufficient fertilizer to supply with and could obtain higher output.But the fertilizer efficiency period of common fertilizer is short, in fertilizer, nutrient, particularly nitrogen nutrient release and corn different growth stage are inconsistent to the demand of nutrient, cause utilization rate of fertilizer low.
for this reason, on market, there is people to release miscellaneous long-acting corn composite fertilizer special, for example:
publication number is the Chinese invention patent application " long-acting complex fertilizer additive " of CN1253932, forms preparation by quinhydrones, Dyhard RU 100, complex rare-earth and zeolite powder, and its weight ratio is 2～8 quinhydrones; 3～25 Dyhard RU 100s; 0.1～0.8 complex rare-earth, 70～95 zeolite powders;
publication number is the Chinese invention patent application " a kind of long-acting corn, paddy rice compound fertilizer special " of CN1212249, it is characterized in that this Chemical Mixed Fertilizer main component is: 1～5 part of Dyhard RU 100,5～10 parts of humic acidss, 30～40 parts, urea, 30～40 parts of calcium superphosphate, 13～20 parts, Repone K, 2～4 parts, zinc sulfate.
though technique scheme provide the formula composition of long-acting corn composite fertilizer special each variant, can obtain the effect of effective raising corn yield and quality and there is more existing fertilizer nutrient content Gao Binggeng feature completely, but its composition is more, preparation technology is more complicated, production cost is higher, use is also relatively inconvenient, cannot meet the demand of vast farmers.
Summary of the invention
object of the present invention is just to overcome prior art above shortcomings, provides a kind of special long-acting slow-release corn composite fertilizer.This special long-acting corn composite fertilizer disposable base manure that does in the time of corn seeding applies, and not only reduce agricultural cost, and raw material is extensive, preparation method is simple, has reduced peasant and buy the spending of fertilizer.
the technical solution that the present invention provides is: this long-acting corn composite fertilizer, is characterized in that the parts by weight of the each component of described composite fertilizer are:
20～25 parts, nitrogen, 12～18 parts, phosphorus, 8～12 parts, potassium, 6～8 parts of Dyhard RU 100s, 1～3 part of trace element, 2～4 parts of humic acidss.
for realizing better object of the present invention, the parts by weight of the each component of described long-acting slow-release corn composite fertilizer are: 27 parts, nitrogen, 13 parts, phosphorus, 10 parts, potassium, 6 parts of Dyhard RU 100s, 3 parts of trace elements, 4 parts of humic acidss.
nitrogenous fertilizer is urea (N) content 46.6%, and phosphate fertilizer is diammonium phosphate (P
2
o
5
) content 64%, potash fertilizer is Repone K (KCl) content 60%.
the preparation method of this long-acting corn composite fertilizer that the present invention provides is:
first by the nitrogenous fertilizer in said components, phosphate fertilizer, potash fertilizer, after Dyhard RU 100 is pulverized, drop into mixing and stirring in conventional stirred pot, put into again mixing and stirring in the compound of trace element, humic acid, make at normal temperatures and pressures the additive of powdery adsorb and be wrapped in the surface of granulated fertilizer, can be used as finished product.
compared with prior art, beneficial effect of the present invention is:
1. fertilizer efficiency period is long, and fertilizer efficiency generally can reach 120 days, have early stage slow controlled release put, reach the feature that discharges peak and later stage sustainable supply mid-term, does the disposable bottom application of base manure, exempts to topdress, and makes the farm crop later stage de-fertile;
2. strong stress resistance, has stronger drought resisting, feature disease-resistant, resistant to lodging, promotes farm crop precocity;
3. increase output, robust plant, leaf look dark green, well developed root system, and the bar maturation of living, full seed, on average increases production 10～15%.
Embodiment
below in conjunction with embodiment, concrete technical scheme of the present invention is described further:
embodiment 1
long-acting slow-release corn composite fertilizer, the parts by weight of each component are: 27 parts, nitrogen, 13 parts, phosphorus, 10 parts, potassium, 6 parts of Dyhard RU 100s, 3 parts of trace elements, 4 parts of humic acidss.
first by 27 parts, the nitrogenous fertilizer in said components, 13 parts, phosphate fertilizer, 10 parts, potash fertilizer, after 6 parts of pulverizing of Dyhard RU 100, drop into mixing and stirring in conventional stirred pot, put into again mixing and stirring in the compound of 3 parts of trace elements, 4 parts of humic acid, make at normal temperatures and pressures the additive of powdery adsorb and be wrapped in the surface of granulated fertilizer, can be used as finished product.
in the time of corn seeding, the disposable base manure that does applies, usage quantity 45 ㎏/mus, corn yield 870 ㎏/mus.
Claims (2)
