Abstract
The present invention discloses a kind of granular humic acid type water-loss reducer of soil, the present invention is made of the raw material of following mass percent: Sodium Polyacrylate: 72-75%, rock wool: 5.5-6.5%, plant adhesive: 0.5-0.8% and humic acid: 19-22%, raw material is blended, stir evenly and extrusion granulation after, obtain granular humic acid type water-loss reducer of soil.Have the function of that collaboration promotes water conservation between used each component raw material.Gained water-retaining agent of the invention is graininess, can be uniformly dispersed in fertilizer, improve the utilization rate of fertilizer；And there is preferable water suction, water retention, the permeability of soil can be increased, improve crop yield.
Description
Technical field
The present invention relates to a kind of water-retaining agent.More particularly, to a kind of granular humic acid type water-retaining agent.
Background technique
Water-retaining agent is a kind of hydrophilic high molecular polymer, it is not soluble in water, but can absorb suitable own wt hundred times
Water.Water-retaining agent can quickly absorb, store, discharging the small reservoir of moisture and nutrient, to meet the growth needs of plant.By raw material
Source can be divided into synthetic resin, starch and cellulose family.
The raw material sources of starch water-retaining agent are abundant, and product water absorbent rate is high, but gel strength is low after water suction, long-term to be retained
Property is poor, loses water suction, water retention vulnerable to microorganism decompositions such as bacteriums in use.Cellulose water retention agent water absorbent rate compared with
It is low, while being also easy to be decomposed the ability for losing water suction, water conservation by bacterium.Currently, the main product of water-retaining agent is synthetic resin
Class based on polyacrylate, hydrolysate polyacrylonitrile, vinyl acetate co-polymer, modified poly ethylene alcohols, but is produced
Water-retaining agent mainly based on powdered, in use process, it is difficult to stirred evenly with chemical fertilizer, be sprinkling upon in soil water retaining efficiency compared with
It is low.
Summary of the invention
The first purpose of this invention is to provide a kind of granular humic acid type water-loss reducer of soil.
Second object of the present invention is to provide a kind of preparation method of granular humic acid type water-loss reducer of soil.
In order to achieve the above first purpose, the present invention adopts the following technical solutions:
A kind of granular humic acid type water-loss reducer of soil, by following weight percent material composition:
Sodium Polyacrylate: 72-75%；
Rock wool: 5.5-6.5%；
Plant adhesive: 0.5-0.8%；
Humic acid: 19-22%.
Preferably, the plant adhesive includes amylan, gum arabic or vegetable protein glue.
To reach above-mentioned second purpose, the present invention is adopted the following technical solutions:
A kind of preparation method of granular humic acid type water-loss reducer of soil, includes the following steps:
Weight percent is formed are as follows: the Sodium Polyacrylate of 72-75%, the rock wool of 5.5-6.5%, the plant of 0.5-0.8%
Object adhesive, the humic acid mixing of 19-22%, after mixing evenly, extrusion granulation obtains granular humic acid type soil water-retaining
Agent.
Preferably, the partial size of the water-retaining agent after the granulation is 3.2-3.5mm.
Preferably, the dosage of organic water retainer of the present invention is 3-4kg/ mus.
In the present invention, a large amount of strongly hydrophilic group (- COONa) is contained in the strand of Sodium Polyacrylate, therefore it is inhaled
It is moist extremely strong.Dry products in air can be with the 10% of moisture absorption self weight, and 1000 times of self weight then can be absorbed in high hydroscopic resin
Above distilled water.The granule that Sodium Polyacrylate can make Zinc fractions stable, so as to improve the farming of soil and the growth of plant,
Reduce water from the loss in soil, avoid when raining heavyly upper layer of soil be flushed away.
Humic acid has good biological activity, is that the organic carrier being made of a variety of functional groups and one have
The intermediate material of plant respiration and photosynthesis metabolic function.Using humic acid, it can be changed that saliferous in soil is excessively high, alkaline mistake
By force, the physicochemical character of grogs high degree of dispersion, soil texture difference, promotes the formation of soil agreegate, makes it at kilter, from
It and is that good condition is created in plant root growth development.Humic acid can also improve chemical fertilizer utilization ratio.
Plant adhesive is mainly amylan, gum arabic or vegetable protein glue, is added in water-retaining agent preparation process
Starch can form starch-acrylate graft copolymer with Sodium Polyacrylate, enhance water-retaining property and water imbibition.
Rock wool can make water-retaining agent have good thermal insulation property, after applying water-retaining agent, protect using the moisture of absorption
The Thermoregulation nocturnal temperature of part daylight generation is held, so that soil day and night temperature reduces.Water-retaining agent can also be controlled
Moisture content is controlled, and has the function that sustained release.
Raw material Sodium Polyacrylate that the present invention selects, rock wool, plant adhesive, humic acid formula, wherein appoint with lacking
What one compare, not only have respective effect, but also between each other also have synergistic effect, enable be retained effect preferably send out
It waves.
Beneficial effects of the present invention are as follows:
A kind of granular humic acid type water-loss reducer of soil of the present invention is graininess, is suitble to various crops, can mix fertile use,
The big field of crops can be evenly distributed on during fertilising with fertilizer；With very strong water suction, water retention, fertilizer utilization can be made
Rate improves 10% or more, and can increase the permeability of soil, can make 8% or more crop yield.
