Abstract
The invention discloses a bagged water retention controlled release fertilizer and a preparation method thereof. The preparation method is characterized by filling a composite mixed water absorbing agent in a medium-density slot bag of a slot triplet fertilizer controlled release bag; meanwhile, two sets of fertilizers are respectively filled in the other two slot bags of the triplet fertilizer controlled release bag for sealing; the slot triplet fertilizer controlled release bag consists of three connected slot bags with different slot densities; the low-density slot bag is positioned in middle; strip-shaped slots with lengths of 1-2 mm and widths of 0.1-0.3 mm are distributed on bag bodies of all the bags in rows; and the composite mixed water absorbing agent is formed by mixing a water retention agent, polyaspartic acid and polyphosphates in proportion. The water retention agent and the fertilizers are combined by specific fertilizer controlled release bag, so that the continuous and slow release of nutrients is guaranteed, the plant fertilizer removal and the fertilizer water loss are prevented, the water absorbing capacity reduction of salt ions in the fertilizers on the water retention agent is prevented, and the plant fertilizer-water integral controlled release supply is realized.
Description
(1) technical field
The present invention relates to a kind of pouch-type water holding controlled release fertilizer and preparation method thereof, belongs to fertilizer slow release/controlled-release technology field.
(2) background technology
Release/controlled release fertilizer disclosure satisfy that plant in different development stage pair by rate of release and the period of control nutrient
The demand of nutrient, applies Controlled Release Fertilizer and can reduce fertilizer amount and nutrient loss, improve utilization rate of fertilizer, mitigates chemical fertilizer to environment
Pollution, additionally it is possible to reduce fertilizer application frequency, save labour etc..But, the nutrient in release/controlled release fertilizer is only having the environment of water
Middle can just discharge.After release/controlled release fertilizer is manured into soil, needs often to water or have rainfall to keep certain soil water-containing
Amount is only possible to make the nutrient sustained release in release/controlled release fertilizer, and the release/controlled release fertilizer for releasing water function with water conservation can then meet this
One requires.
At present main water-holding slow-release/Controlled Release Fertilizer is prepared by the combination of water-retaining agent and fertilizer, according to the difference of combination
Different, this kind of fertilizer is generally divided into mix type, peplos (parcel) type, absorbent-type and chemical type.Such as, patent CN101508616 (one
Plant moisture-retention sustained release and release control fertilizer and preparation method thereof) by water-retaining agent spraying suspension outside macromolecule coat fertilizer particle surface is carried out
Layer peplos, belong to peplos (parcel) type；CN103819276A (a kind of high-moisture-retention slow release marine alga fertilizer and preparation method thereof) exists
Marine alga fertilizer outer layer covers super absorbent resin, falls within peplos (parcel) type.
, all there is complex manufacturing, cost and price height, popularization in various types of water-holding slow-release/release and release control fertilizers at present
And the problems such as application difficult；And, after water-retaining agent imbibition therein formed gel intensity decreases, part fertilizer expose and
Separate out, makes the slow-releasing of fertilizer become unstable, uneven；These water keeping fertilizers are all that water-retaining agent is mixed in one with fertilizer friendship
Rise, the ion discharged by fertilizer significantly reduces the water absorbent rate of water-retaining agent and sticking amount, therefore, or existing water keeping fertilizer is inhaled
Water multiplying power is low, or nutrient content is low, it is difficult to satisfactory to both parties.
(3) content of the invention
For overcoming the shortcomings of existing water-holding slow-release/release and release control fertilizer, the invention provides a kind of pouch-type water holding controlled release fertilizer and its
Preparation method, it is characterised in that 1～10 part of compound water absorbing agent of parts by weight is loaded a slit-type triplet fertilizer control release
In the Midst density slit bag of bag, while the fertilizer of 50～100 parts of two groups of parts by weight is respectively charged into above-mentioned triplet fertilizer control
Release in two other slit bag of bag；The volume for loading the compound water absorbing agent in each slit bag and fertilizer is less than each of which institute
The 70% of the cavity volume for being formed in slit bag；Fertilizer and compound water absorbing agent pack after sealing this product；
Described slit-type triplet fertilizer control release bag be by the high density slit bag for being provided with opening, Midst density slit bag and
Low-density slit bag disjunctor is constituted, and low-density slit bag is located in the middle of high density slit bag and Midst density slit bag；Each slit bag
Bag length is 80～180mm, width and is 50～80mm, be all dispersed with rows thereon long 1～2mm, wide by 0.1～
The strip slit of 0.3mm；The strip slit gross area on high density slit bag accounts for whole high density slit bag bag area
0.8%～1.0%, the strip slit gross area on Midst density slit bag accounts for whole Midst density slit bag bag area
0.4%～0.6%, the strip slit gross area on low-density slit bag accounts for whole low-density slit bag bag area
0.05%～0.2%；
Described compound water absorbing agent be according to parts by weight by 50～100 parts of agricultural water-retaining agent, 1～5 part of poly- Radix Asparagi ammonia
The mixture that acid, 1～5 part of polyphosphate are mixed.
The invention has benefit that：
Slowly moisture can be discharged after the water suction of compound water absorbing agent, make fertilizer Soil Surrounding in moisture state, be conducive in bag
Fertilizer continues and lentamente Releasing nutrient, it is to avoid fertilizer nutrient interrupts release because of hydropenia, and then can avoid being likely to occur
De- fertilizer problem；The water sorption of water-retaining agent can also reduce fertilizer nutrient to be occurred being lost in because rainfall or irrigation quantity are excessive.
The salt ion of fertilizer release can reduce the water absorbing capacity of water-retaining agent.Poly-aspartate and Quadrafos have water sorption
With chelation, they all can form chelate with metal ion, reduce ionic strength, and and then mitigate salt ion to water-retaining agent
The reduction effect of water absorbing capacity；Additionally, poly-aspartate and Quadrafos contain nitrogen and phosphorus element, plant absorption profit is available for
With.Poly-aspartate also adsorbable nutrient, it is to avoid nutrient too fast release when having water.
Fertilizer can reduce the salt ion in fertilizer and enter water-retaining agent and reduce water-retaining agent from water-retaining agent in different bag
Water absorption, is conducive to the high-absorbable for enabling water-retaining agent to be kept for the long period.Nutrients release in high density slit bag is fast, easily
The part salinity in fertilizer is made to penetrate into water absorbing agent, but, low-density slit bag is by high density slit bag and bag equipped with water absorbing agent
Separate, infiltration of the high density slit bag salinity to water absorbing agent is blocked, and low-density slit bag nutrients release is slow, it is discharged
Salt branch quickly by Root Absorption, be less able to penetrate into water absorbing agent.
