Description
Technical field
The present invention relates to a kind of special slow-release or control-release fertilizer composition of crop, and in particular to a kind of special slow-release or control-release fertilizer group of summer corn
Compound and preparation method and application.
Background technology
Slow-release or control-release fertilizer, broadly also known as controlled availability fertilizer, refers to that fertilizer nutrient rate of release is slow, acquisition time is longer, is making
The whole growth period of thing can meet the fertilizer that plant growth is needed；But refer to preset by various mechanism measures in the narrow sense
Fertilizer makes its nutrient element releasing rule absorb basic synchronization with crop nutrition content, so as to reach in the release mode of crop growing season
Improve a class fertilizer of fertilizer efficiency purpose.At present, existing corn slow-release or control-release fertilizer, the only slow control to nitrogen, and slow control phase were on 50 days left sides
The right side, and the coating premature rupture nitrogen having discharges in advance, causes nutrient loss, plant recovery of nutrient is low, does not reach slow-release or control-release fertilizer
Effect and effect, or even have burn kind and burn seedlings phenomenon；Meanwhile, existing corn slow-release or control-release fertilizer is studied very the slow control of potassium
It is few, cause after the potassium in fertilizer is manured into soil, corn growth early stage soil potassium is excessive, and July, August part soil dry-wet are handed in addition
For frequent, the solid potassium of SOIL CLAY MINERALS and potassium leaching loss are aggravated, and the utilization ratio of potassium is low, causes corn growth later stage potassium deficiency,
Influence the yield and quality of corn；In addition, content standard micro- in existing corn slow-release or control-release fertilizer is not high.Therefore, it need to look for
The slow-release or control-release fertilizer high, environmentally friendly, safe, economic with a kind of fertilizer efficiency period length, utilization rate is screened is Future Development trend.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of special slow-release or control-release fertilizer composition of summer corn and preparation side
Method and application, the special slow-release or control-release fertilizer composition of the summer corn have slow control time length, efficiently, environmental protection, safety, it is economical the characteristics of.
The present invention solve its technical problem use technical scheme be：
A kind of special slow-release or control-release fertilizer composition of summer corn of the present invention, matter is pressed by synthetic one, synthetic two, synthetic three
Amount is made than 1: 5: 4；Wherein, synthetic one is made up of the raw material of following mass percent：Calcium magnesium phosphate 30%, potassium sulfate
40%th, white vitriol 15%, ferrous sulfate heptahydrate 10%, borax decahydrate 5% are made；Synthetic two is by following mass percent
Raw material be made：Urea 47.5%, MAP 17.5%, potassium chloride 20%, 10% sulphur, 5% ethene-vinyl acetate are total to
The mixture of polymers and paraffin；Synthetic three is made up of mass ratio of 6: 1 urea with formaldehyde.
Further, N-P in the slow-release or control-release fertilizer composition2O5-K2O-Zn-S mass ratio is 28: 6: 8: 1: 1.
Further, the mass ratio of the ethylene-vinyl acetate copolymer and paraffin is 4: 6.
A kind of preparation method of the special slow-release or control-release fertilizer composition of summer corn of the present invention, comprises the following steps：
(1) preparation of synthetic one：The raw material centered on potassium sulfate, ferrous sulfate heptahydrate, borax decahydrate, with seven water sulfuric acid
The sprinkling of the zinc aqueous solution is caused after core, then 3~4mm of particle diameter fertilizer is made in uniform addition calcium magnesium phosphate coating；The skill
Art granulation can be uniformly distributed various nutrients in fertilizer, and fertilizer efficiency length, plant recovery of nutrient are high.Wherein, calcium magnesium phosphate rich in calcium, magnesium,
Silicon etc., phosphorus content is 12%~14%, CaO content 25~30%, SiO2Content 40% or so, content of MgO 5% or so can promote
Enter the growth of summer corn fibr tissue, having summer corn preferably prevents the ability of lodging and pest and disease damage, with potassium sulfate, sulfuric acid
Zinc, ferrous sulfate, the mixing of borax core material, can meet the early stage needs of summer corn N P and K, phosphorus be met again micro with
The whole breeding time of element and silicon element needs；
(2) preparation of synthetic two：First urea, MAP, potassium chloride are uniformly mixed, granulated according to prior art
Afterwards, then with sulfur coating, then with ethylene-vinyl acetate copolymer and mineral wax mixture enveloping, be made particle diameter 3~
4mm fertilizer, using two layers of coating of sulphur and ethylene-vinyl acetate copolymer (EVA) and mineral wax mixture, especially ethene-
Acetate ethylene copolymer (EVA) and mineral wax mixture second layer coating, fertilizer efficiency period are long, and it is whole that N P and K release had both met corn
The need for breeding time, soil fixing and the loss of leaching loss are reduced again；
(3) preparation of synthetic three：By urea and formaldehyde hybrid reaction, 3~4mm of particle diameter ureaformaldehyde fertilizer is made
Material, the slow control effect of fertilizer efficiency length is good, the need for the corn growth middle and later periods can be met well to nitrogen；
(4) preparation of slow-release or control-release fertilizer composition：Synthetic one, synthetic two, synthetic three are well mixed in mass ratio,
Slow-release or control-release fertilizer composition.
A kind of special slow-release or control-release fertilizer composition of summer corn of the present invention is applied in plantation summer corn, by every mu of summer corn
500kg~800kg yield levels, every mu can apply 50kg~80kg slow-release or control-release fertilizer compositions, once be applied when summer corn is sowed
With.
Further, when summer corn is sowed, by seeding machinery, by the special slow-release or control-release fertilizer composition of summer corn and summer corn
Seed is vertically added, and is above seed, and lower is the special slow-release or control-release fertilizer composition of summer corn, and the horizontal interval distance of sowing is
8~10cm.
Slow-release or control-release fertilizer composition increases Maize Production benefit to be a kind of containing corn yield and its fertilizer efficiency is improved in the present invention
Many kinds of substance mixture.
The special slow-release or control-release fertilizer composition of summer corn of the present invention compared with prior art, is imitated with following beneficial technology
Really：
(1) have the slow control time long, entirely, nutrients ratio and rate of release are well positioned to meet summer corn whole process to nutritional ingredient
It is with strong points, hence it is evident that to improve plant recovery of nutrient needed for growth, enhance growing and resistance ability for summer corn；
(2) defects such as volatilization, leaching loss and the phosphorus, the leaching loss of potassium, fixation of nitrogen are reduced, fertilizer are reduced to environment
Pollution；
(3) fertilizer amount is saved, yield of Summer Corn is improved, economic benefit, social benefit and ecological benefits are added；
(4) it is disposable as base fertilizer, without topdressing, burn seedlings is both prevented, labor cost is saved again, is more beneficial for
Mechanized application.
It is demonstrated experimentally that the special slow-release or control-release fertilizer composition of the summer corn of the present invention is averagely saved in sowing time for summer corn applied once
Fertilizer amount 21.76% is saved, summer corn volume increase 11.35% increases economic benefit 23.33%, and it is 70~80 days to delay the control phase.
