Description
Technical field
The invention belongs to Agro-ecology, soil improvement regulates and controls field with plant nutrient, and be more particularly to is a kind of with mistake
Calcium oxide is substrate, nanometer organobentonite and slow-release oxygen agent that hard paraffin is peplos, also relates to a kind of with peroxide
Changing the preparation method of the slow-release oxygen agent that calcium is substrate nano organobentonite and hard paraffin is peplos, this slow-release oxygen agent can
Effectively cut down the poisonous reducing substances in gleying rice field, and can be Oryza sativa L. oxygen supply, moreover it is possible to improve acid gleying paddy soil pH,
Improving gleying paddy rice growing environment, the slow-release oxygen agent of preparation is applicable to during the Rice Cropping in vast gleying rice district latent
The improvement in educating rice field.
Background technology
Gleyic paddysoil is the modal low-yield land of south China, is distributed widely in Plain Lake and hills and rushes ridge, accounts for
The 1/3 of paddy fields in south china area, and the rice field area in recent years threatened by gleying has the trend of substantially expansion.Gleyic paddysoil by
In being in low-lying landform positions, the long-term accumulated water of soil (or backwater), water-cooled mud temperature is low, poisonous, deleterious reduction material accumulation,
Nutrient Transformation is slow, it is suppressed that the growth of rice root and the absorption to soil nutrient thereof, thus seriously restricts rice high yield.As
What efficiently utilizes gleying rice field, is not only related to China's grain-production, is also related to " amphitypy society " and builds, simultaneously to region
Agriculture and socioeconomic sustainable development is significant.
The Crack cause of gleying rice soil, is first that permeability is bad, next to that a large amount of decomposable asymmetric choice net aerobic substance exists,
Being impeded drainage again, cropping system is improper.Gleying rice soil maximum feature is also soil anoxia.Having of gley paddy soil
Although machine matter is accumulated more, but decomposing slowly, mineralization is more weak.Due to anoxia, cause the reducing substances in paddy soil
Accumulation, such as hydrogen sulfide, small molecular organic acid, the bivalence Fe and Mn etc. of excess, all has greatly rice root growth and Nutrient Absorption
Adverse effect, its to rice root poison reflection be morphologically radical reduce, root system shortens, and distribution reduces, black root
Number increases.Physiologically it is mainly the normal aerobic respiration of block cell pigment oxidation enzyme system, thus affects the normal merit of root system
Can play.Gleization result make reducing substances and ferrous ion accumulation, partial cation is replaced out, accelerate ferrum, calcium,
Phosphorus, potassium, the leaching loss of silicon, cause incobation loss of soil nutrient and degeneration.
Oryza sativa L. normal growth needs sufficient oxygen.The eighties in last century, Japanese scholars Shigeru takes the lead in Oryza sativa L. oxygen
Demand carries out quantitative study, and determines water planting Rice under Condition different growing oxygen demand: tillering stage be 0.27～
0.79mg/ (g h), the jointing stage is 0.95～0.88mg/ (g h), and boot stage is 0.98～1.07mg/ (g h), heading stage
For 0.93mg/ (g h), full heading time is 0.85mg/ (g h), and the period of maturation is 0.68mg/ (g h).The research such as wangdan English is thought
Heading stage is the period that paddy growth oxygen demand is maximum.Soil oxygen concentration is supervised under field condition by Pezeshki etc.
Surveying, result shows, guarantee rice root when oxygen concentration relative atmospheric oxygen content is at least maintained at 3～5% in paddy soil
Normal absorption to oxygen.Therefore, under existing cultivation step, gleying paddy rice easily occurs anoxia to coerce.This is because it is latent
The severe depletion of oxygen of educating rice field, causes the reducing substances in paddy soil such as hydrogen sulfide, small molecular organic acid and the two of excess
The accumulation of valency Fe and Mn etc., causes Root Growth of Rice to be obstructed, and improving activity of root system is poor, root system senilism, limit root system to N, P,
The absorption of the nutrients such as K；Causing under anoxia condition, Oryza sativa L. effective tillering is few, sword-like leave chlorophyll content and SOD activity decrease speed
Hurry up, photosynthesis is obstructed, and dry-matter accumulation reduces, and finally causes grouting insufficient, and setting percentage is relatively low, thus reduces Oryza sativa L. product
Amount.
At present, eliminate or alleviate the measure of rice field gleying and mainly build water conservancy projects, drain flooded fields in time, eliminate stain evil；Secondly
It is that the farming Land use systems changing rice field (as used duck-raising enclosed paddy fields, breeding fish, is planted the industrial crops such as Corm Eleocharitis, or implemented floods and droughts
Crop rotation)；It is the rational application of fertilizer again.But the effect of above-mentioned artificial ameliorative measure is all temporary transient, because causing the gas of rice field gleying
Waiting and geographical environment does not change, therefore, existing technical measures cannot meet the long-term needs of gleying rice field improvement.In a large number
Result of study shows, uses calper calcium peroxide oxidant, can effectively cut down soil reduction process material, improve soil pH, and can also be
Crop supply oxygen, activating soil organic carbon.But calper calcium peroxide oxygen release time in gleying rice field is shorter, it is impossible to meet Oryza sativa L.
The fertility middle and late stage demand to oxygen.The present patent application person is for the key factor reduction of restriction Gleyic paddysoil crop yield
Material, the slow release calper calcium peroxide of Gleyic paddysoil soil reduction process material is effectively cut down in initiative.This technology with calper calcium peroxide as core,
Select suitable binding agent and peplos agent, use nanometer organobentonite and hard paraffin coated slow-release calper calcium peroxide and suitable
Production technology, it is thus achieved that oxygen release time of slow-release oxygen agent product up to more than 100 days, gleying paddy rice can be met and entirely give birth to
Educate the phase demand to oxygen, and improve acid gleying paddy soil pH.
Summary of the invention
It is an object of the invention to there are provided one with calper calcium peroxide for substrate nano organobentonite and hard paraffin

Jet flow amount at the bottom of seed-coating machine is 2 mL/min, end spray pneumatics 0.2 MPa, and stop-spraying is not spilt, until the spraying of paraffin coating liquid is complete；
4. cooling: closing end spray fluidized-bed coating machine warming-up device, air-introduced machine air quantity is adjusted to 1680 m3/ h, by fluid bed
Coated granule is cooled to room temperature, takes out coated granule；
C. face powder:
Being put into by coated granule in granulating disc disk, granulating disc disk inclination angle adjusts to 58 ~ 62 °, and rotating speed is adjusted to
20 r/min, close heating apparatus, weigh Pulvis Talci 21.50 g of the 1% of gross mass after calper calcium peroxide peplos, are put by Pulvis Talci
