Abstract
It is by by weight that the present invention provides a kind of sustained-release synergistic Sorghum vulgare Pers. special bulk blended fertilizer applied in calacareous soil：What 200～400 parts of 400～600 parts of carbamide, 100～300 parts of MAP and potassium chloride were constituted.Carbamide used, MAP and potassium chloride, have very strong Lian Yingxing between three kinds of sources of manure：MAP blends carbamide and can form macromolecule polyalcohol, the gradually Releasing nutrient in soil, forms the slow-release fertilizer without Cotton seeds；Carbamide blends one ammonium of acid phosphatase and potassium chloride, and decomposition of the urase to carbamide, the ammonium hydroxide that carbamide is converted in soil can be delayed to react with MAP, generate Diammonium phosphate (DAP) and water, MAP and chlorination nak response, can generate potassium dihydrogen phosphate and ammonium chloride, all play a part of retain water and nutrients.
Description
Technical field
The invention belongs to sustained-release synergistic Blending Fertilizer field, particularly a kind of sustained-release synergistic Sorghum vulgare Pers. applied in calacareous soil is special
Use bulk blended fertilizer.
Background technology
In the nineties in last century, in the face of occur in agricultural production " no matter water ground nonirrigated farmland, pursues nitrophosphate fertilizer simply；
No matter soil acid-base, supertition Diammonium phosphate (DAP) always；Crop regulation of fertilizer requirement is not pressed, all the year round single nitrogen fertilizer application；Chemical fertilizer characteristic, carbonic acid are not seen
Hydrogen ammonium is year after year mixed with calcium magnesium phosphate " the phenomenon that do not apply fertilizers scientifically, cause the passive situation that crop yield is fluctuated all the year round；
Just go into operation for several MAP factories in Henan Province at that time, because manufacturer publicizes not in place, peasant does not know its usage, causes product
A large amount of reality for overstocking, MAP factory of Xinmi City has also put into effect each worker and has not sold the policy that two tons of MAPs are not raised wages,
Produced problem in production, is exactly the problem of our researchs, is badly in need of this acid fertilizer of one ammonium of application of phosphoric acid for calacareous soil
The truth of material, by field test, works out the disclosed bulk blended fertilizer in calacareous soil with MAP as phosphorus source.This generation
Recording just, the report of result of laboratory test being sampled for 748 sample points of different soils, Soil Available potassium content was dropped every 3～5 years
It is low by 10.8%～14.9%；27.1%～29.9% phenomenon was reduced every 10 years." accelerate efficiently peaceful fertilizer to grind according to country
Send out " policy requirements, in original " MAP Erbium-doped closes carbamide fertilizer efficiency research on Semen Tritici aestivi " for obtaining and " MAP is in Calx
Property soil on fertilizer efficiency research " on the basis of two scientific achievements, increase with potassium chloride, research MAP blends carbamide and chlorination
Lian Yingxing between potassium their threes, develop " fertilizer efficiency is high, price is low, with strong points, adapt to terra calcis Reel apply it is each
Plant crops bulk blended fertilizer formula ", the sustained-release synergistic Sorghum vulgare Pers. mixing fertilizer specially, is exactly one kind therein.
The content of the invention
In sum, in order to overcome the shortcomings of prior art problem, according to the principle of balance fertilizing " law of cask ", this
It is bright to develop a kind of sustained-release synergistic Sorghum vulgare Pers. special bulk blended fertilizer applied in calacareous soil.Carbamide used, MAP and chlorine
Change potassium, between three kinds of sources of manure, have very strong Lian Yingxing：MAP blend carbamide can form macromolecule polyalcohol, in soil by
Gradually Releasing nutrient, forms the slow-release fertilizer without Cotton seeds；Carbamide blends one ammonium of acid phosphatase and potassium chloride, can delay urase pair
The decomposition of carbamide, the ammonium hydroxide that carbamide is converted in soil are reacted with MAP, generate Diammonium phosphate (DAP) and water, phosphoric acid one
Ammonium and chlorination nak response, can generate potassium dihydrogen phosphate and ammonium chloride, all play a part of retain water and nutrients.
To solve above-mentioned technical problem, the technical solution used in the present invention is：
A kind of sustained-release synergistic Sorghum vulgare Pers. special bulk blended fertilizer applied in calacareous soil, wherein, described bulk blended fertilizer is
By carbamide, MAP, potassium chloride by weight：400～600 parts of carbamide, 100～300 parts of MAP and potassium chloride 200
～400 parts of compositions.
Further, described a kind of sustained-release synergistic Sorghum vulgare Pers. special bulk blended fertilizer applied in calacareous soil, wherein, it is described
Bulk blended fertilizer be by carbamide, MAP, potassium chloride by weight：500 parts of carbamide, 200 parts of MAP and potassium chloride
300 parts of compositions.
Further, described a kind of sustained-release synergistic Sorghum vulgare Pers. special bulk blended fertilizer applied in calacareous soil, wherein, it is described
Bulk blended fertilizer be by carbamide, MAP, potassium chloride by weight：525 parts of carbamide, 225 parts of MAP and potassium chloride
250 parts of compositions.
Further, described a kind of sustained-release synergistic Sorghum vulgare Pers. special bulk blended fertilizer applied in calacareous soil, wherein, select
Carbamide, MAP, three kinds of sources of manure of potassium chloride characteristic it is as follows：Carbamide nitrogenous 46.3%；The MAP of slurry process production contains
Nitrogen 11%, phosphorus 44%；Potassium chloride contains potassium 60%.
Beneficial effects of the present invention：
The Sorghum vulgare Pers. mixing fertilizer specially that the present invention is developed possesses following four advantage：1. using safety, as it can delay
Rate of release of the nutrient to rhizosphere, even if single-dose application amount exceedes the absorbability of root system, is also avoided that high concentration salinity to making
The harm of thing root system；2nd, save labor, fertilizer can meet needs of the plant growth period to nutrient by one-time use,
Labour, and reduces cost are saved not only；3rd, nutrient efficiency is improved, the slow release fertilizer can reduce the phase mutual connection between nutrient and soil
Touch, so as to reducing biology because of soil, chemically and physically acting on the fixation to nutrient or decomposition, improve the utilization ratio of fertilizer.
4th, environmental protection.Work out MAP and blend the Lian Yingxing between carbamide and potassium chloride their threes：MAP blends urine
Element can form macromolecule polyalcohol, the gradually Releasing nutrient in soil, form the slow-release fertilizer without Cotton seeds；Carbamide blending acid
Property MAP and potassium chloride, can delay decomposition of the urase to carbamide, ammonium hydroxide and phosphoric acid that carbamide is converted in soil
One ammonium reacts, and generates Diammonium phosphate (DAP) and water, MAP and chlorination nak response, can generate potassium dihydrogen phosphate and ammonium chloride, all rise
To the effect of retain water and nutrients.The bulk blended fertilizer, without " coating " process, so process is simple, fertilizer efficiency be high, price is low.
