QUANSEN retainsupport® superabsorbent application in Desert Greening

QUANSEN retainsupport® superabsorbent polymer in improving the ecological environment and role  play to decide the success or failure of the windbreak project. When the  desert greening, the simple method of applying QUANSEN retainsupport® superabsorbent polymer can greatly improve the survival rate of seedlings and plant growth.

( 1 ) Using cuttings, grafting, tissue culture seedlings and seed  breeding of tree, shrub seedling nursery ground effects of Super absorbent  polymers, seed germination and rooting will accelerate, seedling growth is  faster, more robust, and in the process of porting the affected is very  small. According to the breeding and planting of seedlings of different  insurance agent applicator, pocketing, furrow fertilization in the soil  mix. Experiments show that seedling root growth into the QUANSEN retainsupport® superabsorbent polymer crystals, if a strain of plant roots can bring50~200 tablets of QUANSEN retainsupport® superabsorbent polymer crystals, the transplant can greatly reduce drought on transplanting  and growth of adverse effects. On transplanting survival difficult plant,  seedling transplant survival rates also increase. Economic analysis,  cost-per-retaining agent for transplanting seedlings take about 0.03 Yuan. For most green seedlings  and seedlings of fruit trees, this expenditure is completely  unacceptable.     

( 2 ) Seedlings dipped in root Bare-root seedlings after the  digging, in the process of packing, transport and temporary storage, face the  problem of dehydration effects of root system survive. Root dip mixed  clay, water retention agent, and water and mud, dip than other materials (such  as wood) into the moisturizer effect is much better. Because retaining  agents more water, and even use powdered water retaining agent, after water  absorption remains inherent in rhombus shape, also allow normal breathing roots  while moisturizing. Moisturizing mud preparation: fine  water retaining agent: clay: water = 1 ∶ 150 ∶ 200 Each seedling tape 100 grams of this Super  absorbent slurry calculations, each using aquasorb cost only 0.02 Yuan, can be  described as "economic and reliable".

( 3 ) Nursery stock transplanting When planting bare-root seedlings  of trees, shrubs and lianas, and when we fill planting hole, 1 ~ 2 Cups ( 250 ~ 500 G) seedling roots of aquasorb  Hydrogel is applied, then fill can be. Each seedling cost only about  application of QUANSEN retainsupport® superabsorbent 0.06~0.15 , can reduce the risk of death of seedlings 50% above.

( 4 ) Dealing with the growth of the trees

Due to drought or other factors resulting in declining trees or drop of  fruit trees, and in the vertical projection of the Crown range, combines dig  ring groove (Groove) application of organic fertilizers, QUANSEN retainsupport® superabsorbent polymer mix applies to both the tree root. Amount of water retaining agent  for: hydrogels of backfill soil 30%, or dry granular backfill 2~3per thousand.

Soil is the growth of  the trees by drilling application of QUANSEN retainsupport® superabsorbent in a better  way. Using high efficiency, simple operation, saving time and working machinery to drill, drill holes in Crown point down under the scope, quantitative water retaining agent and method of organic fertilizer mixture  soil backfill the hole. With the traditional method of circle furrow,  ditch, radiation channel or plowing into the law, drilling method has many advantages.

QUANSEN retainsupport® superabsorbent application in Fix Heavy Meatals in soil

At present QUANSEN retainsupport® superabsorbent On heavy metal pollution in soil remediation of start-ups. There are many problems to be studied. Such as:QUANSEN retainsupport® superabsorbent on an individual and a variety  of heavy metal and its scope of effect soil contamination? QUANSEN retainsupport® superabsorbent in soil water and nitrogen and phosphorus under different conditions, single and combined pollution of heavy metals on the curing effect? QUANSEN retainsupport® superabsorbent , plant growth and mechanism of soil mass effect ? QUANSEN retainsupport® superabsorbent in soil fertilizer and heavy metal pollution  governance in the of ecological risk evaluation soil heavy metal pollution  repair method main including physical, and chemical and biological three big  class, which physical repair including physical hot off method, and separation  method, and new soil replacement method, and curing stable method and electric  power method,, chemical method including solvent extraction method, and chemical leaching method, and passivation method and the oxidation restore  method,, biological repair method including microbial repair method, and plant  repair method and animal repair method,. Bibliometric analysis show that  bioremediation and chemical curing technology and its supporting is the soil  heavy metals remediation research and applications. Among them, chemical  stability and passive curing is an important direction of development, the  principle is added to the soil passivation material, through physical and  chemical adsorption, precipitation, complexation and redox effects such as  changing the State of heavy metal, increasing the proportion of residues of  heavy metals and organic State, reduce the bioavailability of heavy  metals. At present, the passivation of heavy metals in farmland-curing  materials include lime, clay minerals, phosphate, and mineral absorption  materials such as zeolite, as well as organic fertilizer and microbial. QUANSEN retainsupport® superabsorbent was recently found to have a curing effect of heavy metal material.

Cross joint QUANSEN retainsupport® superabsorbent Can promote bacteria in wastewater Cd Zn Stabilization to remove. QUANSEN retainsupport® superabsorbent not only to promote soil conservation soil and decreased soil Cu, andZn, andPb content of soluble State.Found that the polyacrylate salt QUANSEN retainsupport® superabsorbent may change the physical and chemical properties of the soil,  soil pH, soil Cu, andCd and Ni , AndZn bioavailability.

Pot experiments show that soil 0.2%QUANSEN retainsupport® superabsorbent Can reduce soil  of the sorghum Cd And the bioavailability of  plant growth. Containing heavy metals Cu, andPb, andAl, andAs such as remediation of  contaminated mineral waste yard to add QUANSEN retainsupport® superabsorbent application 75-170kg/hm2 , Can improve the soil water retention and nutrient absorption,  reduced plant uptake of heavy metals.

QUANSEN retainsupport® superabsorbent Farmland has a direct effect on plants, there is through the  improvement of soil physical and chemical properties and the indirect effects  of soil organisms, through reduced bioavailability of heavy metals in two  ways. Pot experiments proved that environmental material (HA HA, andQUANSEN retainsupport® superabsorbent, fly ash FM and zeolite FS) and composite F1, and F2 F3 (RespectivelyFM+QUANSEN retainsupport® superabsorbent+HA+FS FS+HA+QUANSEN retainsupport® superabsorbent  FM+QUANSEN retainsupport® superabsorbent+HA ) On the growth of corn, soybean and soil heavy  metals Pb Cd Absorption effects. A single environment materials and composite  control significantly reduce the absorption of heavy metals Pb, andCd, and promote crop growth. QUANSEN retainsupport® superabsorbent and its composite F3, andF2 on the soil heavy metals Pb, andCd of the curing effect. The  comparison,QUANSEN retainsupport® superabsorbent composite can be corn Pb uptake compared to  reduce 50% aboveCd reduction 80% Above; QUANSEN retainsupport® superabsorbent Composites the soybean absorbs  heavy metals Pb Reduced 69% Above, Cd Reduced 33% Above. Studies have found thatQUANSEN retainsupport® superabsorbent and its composite material of  soil Pb, andCd passivation effect of curing and the soil pHand theEC , Organic matter, nutrients, and soil enzyme activities change are  closely related.

Qu Guiwei reported using Super absorbent polymers, such as removal of  industrial waste water and the feasibility of heavy metals in the  soil. Tests found that retaining agents in improving crop root water  supply and improve the soil structure at the same time, can significantly  reduce the corn, soybean and other crops on absorption of cadmium and lead in  soil. Will hydrated manganese oxide nanoparticles mixed into salt water  retaining agent in POLYACRYLIC acid, can also improve water retaining agent  on Cd (II) absorption capacity, thereby  reducing the plants, so that the material can be used for in-situ remediation  of cadmium pollution in soil. Discovered and confirmed these previous  studies, transfer agent reducing soil cadmium plant. Containing heavy  metals Cu, andPb, andAl, andAs such as remediation of  contaminated mineral waste yard to add QUANSEN retainsupport® superabsorbent application 75-170kg/hm2 , Can improve the soil water retention and nutrient absorption,  reduced plant uptake of heavy metals. From the perspective of removal of  copper ions, water retention agent is an ideal material, and larger quantities  of water absorbent and water absorption for a long time, the removal of copper  ion the better. But it is worth noting is that greater combined capacity  of copper ions and water retaining agent.

Light pollution and a  wide range of agricultural soils, passivation method is relatively quick feasible  method. This fix has low investment, simple operation, without destroying  the original soil structure characteristics and effect of its implementation  depends on soil and environment has no side effects on heavy metal adsorption  and fixation capacity and relatively strong material. Studies have found  that water retention agent is a strong water absorbing capacity of the special  polymer material, can absorb water, fertilizer, pesticide and then released  slowly so as to increase efficiency and efficacy, and harmless to the human  body, no pollution has been widely applied in many areas, especially in  agriculture. Super absorbent polymers can be divided into starch,  cellulose and synthetic polymers, their common point is the molecule with a  large number of carboxyl and hydroxyl groups, so in theory, they can be by  complexing adsorption of heavy metal ions, removing it from the environment.
