Abstract
The invention relates to a slow-release synergistic bulk-blended fertilizer applicable to calcareous soil, prepared from, by weight, 400-800 parts of urea, 200-400 parts of monoammonium phosphate and 80-160 parts of potassium chloride. The three fertilizer sources are high in mutual adaptability, monoammonium phosphate may be blended with urea to form a macromolecular polymer that releases nutrients slowly in soil, and coating-free slow-release fertilizer is formed; urea may be blended with acidic monoammonium phosphate and potassium chloride to delay decomposition of urea, ammonium hydroxide converted from urea in soil reacts with monoammonium phosphate to generate diammonium phosphate and water, and monoammonium phosphate may react with potassium chloride to generate ammonium dihydrogen phosphate and ammonium chloride, both acting for holding water and fertilizer; by adding potassium fertilizer to the bulk-blended fertilizer, the slow-release synergistic bulk-blended fertilizer may provide an increase of 8.9% in wheat yield when compared to nitrogen-phosphorus bulk-blended fertilizer, the bulk-blended material requires no coating, coating is not required, the process is simple, fertilizer efficiency is high, and the price is low.
Description
Technical field
The present invention and bulk blending slow release fertilizer field, particularly a kind of sustained-release synergistic Bulk Blending Fertilizer in calacareous soil administration.
Background technology
In recent years, occur that much dragons and fishes jumbled together on the market, the Controlled Release Fertilizer under silt and slow-release fertilizer, have even also identifies
Fertilizer for " quick-acting sustained release ".According to the policy requirements of " accelerating efficiently peaceful fertilizer research and development ", using production bulk blended fertilizer " equipment
Simple small investment, handling ease is pollution-free, and the less price that consumes energy is low, and formula is flexibly changed the line of production soon, and fertilizer efficiency with strong points is high, Yi Shizhen
The advantages of pseudo- anti-counterfeiting ".China's calacareous soil distribution is very wide, according to estimating, accounts for about the half of national cultivated area.In stone
How Rational Application phosphate fertilizer on ash soil, some fertilizer efficiency are very notable, and the fertilizer efficiency also having is not notable.Disclosed have " MAP
Blending urea is in calacareous soil fertilizer efficiency research " on the basis of scientific achievement, join potassium chloride and study MAP blending
Lian Yingxing between urea and their threes of potassium chloride, make " fertilizer efficiency, price are low, with strong points, adapt in terra calcis
The bulk blended fertilizer that earth is applied "；In the nineties in last century, we in the face of occur in agricultural production " no matter water ground nonirrigated farmland, simply
Pursue nitrophosphate fertilizer；No matter soil acid-base, supertition Diammonium phosphate (DAP) always；Do not press crop regulation of fertilizer requirement, throughout the year single nitrogen fertilizer application；Do not see
Chemical fertilizer characteristic, ammonium hydrogen carbonate is year after year mixed with calcium magnesium phosphate " the phenomenon that do not apply fertilizers scientifically.Push away all the year round for rational application of fertilizers technology and
The difficult problem do not opened, according to the requirement of " change rational application of fertilizers be apply formula fertilizer ", disclosed in calacareous soil with MAP as phosphorus
The fertilizer efficiency in source is higher, than Diammonium phosphate (DAP), nitrophosphate fertilizer, calcium magnesium phosphate for phosphorus source increase production respectively wheat 8.36%, 16.14%,
91%；The formula fertilizer efficiency that MAP blends urea is higher：Ratio blends ammonium nitrate, ammonium sulfate, ammonium chloride, ammonium hydrogen carbonate and auxiliary
Wheat 10.2%, 11.4%, 11.9%, 30.5%, 95.6% is increased production in comparison (calcium magnesium phosphate+ammonium hydrogen carbonate) respectively.From to not
Be sampled the report of result of laboratory test with 748 sample points of soil, Soil Available potassium content every 3～5 years reduce by 10.8%～
14.9%；Reduce by 27.1%～29.9% phenomenon every 10 years.Nitrogen, phosphorus two essence bulk blended fertilizer increase and joins potash fertilizer.
Content of the invention
In sum, in order to overcome the shortcomings of prior art problem, the present invention have developed one kind and applies in calacareous soil
Sustained-release synergistic Bulk Blending Fertilizer, it is the principle according to balance fertilizing " law of cask ", develop suitable for limed apply
Sustained-release synergistic Bulk Blending Fertilizer.There is very strong Lian Yingxing, MAP blends urea and can form macromolecular polymeric between three kinds of sources of manure
Thing, gradually Releasing nutrient in soil, form the slow-release fertilizer without Cotton seeds；Urea blends acid phosphatase one ammonium and chlorination
Potassium, can delay the decomposition to urea for the urase, and the ammonium hydroxide that urea is converted in soil and MAP react, and generate phosphoric acid
Two ammoniums and water, MAP and chlorination nak response, can generate potassium dihydrogen phosphate and ammonium chloride, all play the effect of retain water and nutrients.
The calacareous soil being 68.73 mg/kg in quick-acting potassium content, increases in bulk blended fertilizer and joins potash fertilizer, compared with nitrogen, phosphorus Was Used
Bulk Blending Fertilizer, volume increase wheat reaches 8.9%；This bulk blended fertilizer, without coating " process, so process is simple, fertilizer efficiency be high, price is low.
For solving above-mentioned technical problem, the technical solution used in the present invention is：
A kind of sustained-release synergistic Bulk Blending Fertilizer in calacareous soil administration, wherein, described sustained-release synergistic Bulk Blending Fertilizer is by urinating
Element, MAP, potassium chloride are by weight：400～800 parts of urea, 200～400 parts of MAP and potassium chloride 80～160
Part composition.
Further, described a kind of sustained-release synergistic Bulk Blending Fertilizer in calacareous soil administration, described sustained-release synergistic blends
Fertilizer is by urea, MAP, potassium chloride by weight：600 parts of urea, 300 parts of MAP and 100 parts of compositions of potassium chloride
's.
Further, described a kind of sustained-release synergistic Bulk Blending Fertilizer in calacareous soil administration, described sustained-release synergistic blends
Fertilizer is by urea, MAP, potassium chloride by weight：500 parts of urea, 350 parts of MAP and 150 parts of compositions of potassium chloride
's.
Further, described a kind of sustained-release synergistic Bulk Blending Fertilizer in calacareous soil administration, from urea, MAP,
The characteristic of three kinds of sources of manure of potassium chloride is as follows：Urea nitrogenous 46.3%；The MAP that slurry process produces is nitrogenous 11%, phosphorus 44%；
Potassium chloride contains potassium 60%.
Beneficial effects of the present invention：
The present invention develops to be had between three kinds of raw material sources of manure of sustained-release synergistic Bulk Blending Fertilizer that suitable for limed is applied
Very strong Lian Yingxing：MAP blends urea and can form macromolecule polyalcohol, gradually Releasing nutrient in soil, formed without
The slow-release fertilizer of Cotton seeds；Urea blends acid phosphatase one ammonium and potassium chloride, can delay the decomposition to urea for the urase, urea is in soil
The ammonium hydroxide being converted in earth and MAP react, and generate Diammonium phosphate (DAP) and water, MAP and chlorination nak response, can give birth to
Become potassium dihydrogen phosphate and ammonium chloride, all play the effect of retain water and nutrients.The lime being 68.73 mg/kg in quick-acting potassium content
Property soil, increase in bulk blended fertilizer and join potash fertilizer, compared with nitrogen, the Bulk Blending Fertilizer of phosphorus Was Used, volume increase wheat reaches 8.9%；This bulk blended fertilizer,
Without coating " process, so process is simple, fertilizer efficiency be high, price is low.
