QUANSEN retainsupport® superabsorbent application in modern agriculture
What’s the superabsorbent?
Retaining agents using high water-absorbent resin, it is a kind of water absorbing capacity particularly strong functional polymer materials. Harmless, repeatedly releasing water, absorb water, agriculture people compare it to " micro-reservoirs ". Meanwhile, it also can absorb fertilizers, pesticides, and slow-release, increased efficiency and efficacy. High water-absorbent resin is widely used in agriculture, forestry, horticulture, building materials ; In industry can be widely used in petroleum, chemical, cables, paper, sensors, fire-fighting appliances, fiber products, cosmetics, toys, food preservation, expansion, and so on.
Drought is the events of the world. This century, 50 years since with the rapid development of industry and the rapid expansion of population, climate warming, drought has become increasingly prominent. These problems prompted the scientists to begin research on effective methods to solve the drought problem. 20 century 50 years before human use absorbent materials for natural substances and minerals. Such as natural fibres, natural protein. 50 years,Goodrich company developed a cross-linked POLYACRYLIC acid production technology, makes water-absorbent polymer applied tackifying agents.
Is the emergence of Super absorbent resin 1961 Year USDA Northern Research Institute C.R.Russell Starting from starch grafting acrylonitrile studies, the first of Super absorbent resin on the Heinrich Henkel AG (Henkelcorporation) Industrial success, its trade name SGP(Starch Graft polymer) When the United States mostly agriculture-oriented and applied, first applied in breeding seedling soil improvement, water retention, and so on.
60 To the late 70 Age, United States Starch 、 General Mills Chemical And Japan's Sumitomo Chemical, Sanyo Chemical industries and other companies have successfully developed a high water-absorbing resin. The most effective of these is the United States, Japan, France and Germany.
80 Derivatives began to appear with other natural compounds via chemical reaction producing water-absorbent materials, synthesis of Super absorbent resin of development, promoting the development of applied research.
Absorbent composite 20 Century 80 Era. Because it improves salt tolerance of super water-absorbent resin, water speed, water-absorbing Hydrogel strength properties, developed rapidly. In recent years, has begun to study water-absorbent polymer blending technology. For the development of high water-absorbent material provides a more broad prospects.
High water-absorbent resin by a late start in China, 80 Age started 20 Years have been nearly 20 A unit has carried out research, and some have been transferred to the pilot and small-batch production. Currently has a production capacity of the manufacturers, these plant products are sodium polyacrylate starch grafting sodium polyacrylate, the quality of products, in addition to the compound itself, mainly, technologies, processes and equipment. Imported products are mainly Belgian TC (Terra Cottem vegetation and soil Franz-Josef Kortum for short ), France SNFAQUASORB Super absorbent polymers, Germany Stockhau Sen Stocksorb Insurance agent, along with the country to increase investment and attention to eco-environmental construction, the Superabsorbent polymer product research, development, production of round climax.
Water absorption principle
Water absorption of Superabsorbent polymers the same principle in General SAPs , Is Polymer Electrolyte molecular chain amide group in the water and / Carboxyl group Like charges repel to molecular chain expansion and due to Crosslinking Limit the expansion of molecular chain of interactions. A case study of polyacrylamide, Super absorbent polymer has a lot of amide and carboxy hydrophilic, resin composition of internal ions and radicals associated with aqueous concentration of the osmotic pressure difference and polymer Electrolyte affinity and can be a lot of water uptake and water until the concentration difference disappears. Control QUANSEN retainsupport® superabsorbent reached a satisfactory degree of rubber elasticity. Molecular structure ofCrosslinking degree of higher, stronger rubber elastic and rubber elastic and hydraulic balancing point is its apparent ability to absorb water.
Due to the molecular structure of cross-linked molecular network by water drawn out cannot use physical methods to water retention.
Thus, similarly composed of polymers Degree of Crosslinking The lower water absorption ratio is relatively higher, less water retention, stability and strength, and vice versa.Therefore, international use for a longer period of Super absorbent natural high Crosslinking degree , does not pursue high water absorbency and rate. A case study of polyacrylamide and its apparent rate is not high, water absorption rate varies widely depending on the particle size, strength after high water absorbent, a certain shape, easy to collapse, to soil, water reversibility good absorption. Super absorbent polymer mixed with ground 5 to 15 centimeters, so there is more emphasis on the international water absorbency at elevated pressure. According to particle size, polyacrylamide-water absorption ratio 150-300.
Product category
QUANSEN superabsorbent at present is divided into two categories, one is Acrylamide - Acrylic Salt polymer conjugates ( Polypropylene acyl amine, sodium polyacrylate potassium, ammonium polyacrylate, POLYACRYLIC acid ); The other is Starch Graft copolymerization of acrylate Crosslinking method ( Starch grafted acrylic acid ) 。
Polyacrylamide -- White granular Crystal shape of polyacrylamide, composed mainly of : Acrylamide 65%-66%+ Acrylic Potassium 23%-24%+ Water 8%-10%+ Crosslinking agents 0.5%-1.0% 。 At the international level, France, Germany, Japan, the United States and Belgium and other countries produced most of the QUANSEN retainsupport® superabsorbent in this category of products. The characteristics of the product are : life cycle and longer life expectancy, in soil water conservation capacities last 4 years or so, but its water absorption capacity will be reduced year by year. Experimental observation on afforestation in loess area, after using this type of Super absorbent polymers afforestation in the year of the water absorption ratio remained at 100-120times, water absorbency the following year reduced 20%-30%, the third year is reduced by 40%-50%, fourth year reduce more.
Sodium polyacrylate -- White or light grey granular sodium polyacrylate crystals consist mainly of : Sodium polyacrylate 88%( Containing sodium 24.5%)+ Water 8%-10%+ Crosslinking agents0.5%-1.0%. Most of the domestic production of Super absorbent polymers are components of this product. Its main features are : high water absorbency, absorbing water faster, but water retention is kept for only 2 years. Afforestation trial observation, these products ability to absorb water and water absorption rate significantly higher than that of polyacrylamide products, in case of sufficient water supply in the soil,0.5-1.0 hours after rapid weight 130-140 times as much water ; But reducing water absorption rate for the second year, by about 60% Or so. Because sodium polyacrylate sodium in soil ion content increase Forestry and agricultural Super absorbent polymer manufacturer to produce potassium polyacrylate or ammonium polyacrylate.
Starch Grafting Acrylate -- Starch grafted acrylic acid salts as granular white or light yellow Crystal, mainly composed of : Starch 18%-27%+ Acrylate 62%-71%+ Water 10%+ Crosslinking agents 0.5%-1.0%. This product is used for land when the water conservation, life can only maintain 1 more than a year's time, but water absorbency and water absorption rate, excellent characters. Laboratory of loess extract water absorption experiment this type of Super absorbent polymers in water after 15-20 minutes to absorb weight 150-160 times as much water.

Method of QUANSEN retainsupport® superabsorbent
basic method
QUANSEN retainsupport® superabsorbent polymers on soil water and crop growth of related not only to water absorption and water holding capacity and soil texture, rainfall, irrigation and crop species and so on.
Dip use retaining agents most commonly used root, seed, soil mixing, soil-less cultivation, seed sowing, spreading and wait.
( 1 ) Dipping method
This method is used in small size product.
Is the root system of the plants evenly coated with Super absorbent polymer into liquid paste. Dip the root method, mainly in vegetables, flowers and seedling of naked root transplanting time.
When the vegetable seedlings, as vegetable growing season is shorter, we can choose the short life of the small particles of water retaining agent. Specific methods of operation: first transplanting a whole, dig planting seedlings points in its hole by constant applied phosphate fertilizer as basal, ready for transplanting seedlings, then dipped in liquid preparation. In preparation dipped root liquid Shi, to increased dipped root liquid of dip to, makes root Shang easy hanging Shang more of dipped root liquid, we can will insurance agent and fine dry soil by must of proportion mixed uniform, then again according to products of using description by proportion joined water, insurance agent and water of proportion roughly for 1:300, side added side constantly mixing, makes its full sucking water, mix Hou static reset 3 hours after water absorption of Super absorbent polymers, such as a mud paste. Dip roots the roots of seedlings into the dip solution, roots to try to hang up the dipping liquid, so it can be planted. Attention when planting seedlings in real land around the seedlings, seedling roots could maintain close contact with the soil, planted seedlings time after water flooded. A kilogram of water retaining agent can handle at least 2000 seedlings. In this way, you can improve the survival rate of planting seedlings, shorten the slow time.
In a small tree when transplanting, when dipped in liquid preparation of seedlings of preparation method of the same, only when you select a Super absorbent polymers, our best selection of potassium polyacrylate, because the tree grows long, most of the trees rely mainly on natural rainfall, water supply conditions are relatively poor, so you should use long life, repeated water-absorbing function of Super absorbent polymers. In addition, bare-root seedlings for long distance transportation easily lose water, dip in with Super absorbent polymers, can give seedlings to add water to prevent water loss in the Middle, improve the survival rate of seedlings. Is in need of attention, and dipped water absorbent seedling roots had better wrap it with plastic film, loss prevention is better.
( 2 ) Fertilization method
QUANSEN retainsupport® superabsorbent soil according to a certain proportion of blending, turn it into ditches or cultivation hole. With soil in order to make water retaining agent can be evenly distributed around the plant roots, which is currently the most widely used method, in sowing, planting seedlings, potted plant planting, planting trees and seedling nursery can be used.
For the short growing season of annual crops, at the time of sowing or planting seedlings, we can choose a type of small particles, probably usage per acre 3-5 Kg, number of application specific product descriptions that can be used in accordance with the insurance agent. We take soil, soil can be directly selected field soil, attention to the fine soil, water retention agent and soil about 1:20 ratio blended together, stirring, making it uniform. At the time of application, sprinkle mix the good QUANSEN retainsupport® superabsorbent on seeding Groove or in the planting hole, and then applied the base fertilizer, top with a layer of soil after seeding or planting seedlings and water permeable. After applying this method can reduce more than half the watering frequency, improving the germination rate and seedling survival rate, at the same time, slow time significantly reduced. Vegetables, flowers and other crops when the seedling nursery, Super absorbent polymers and seedling can be 1:100 ratio mix, put inside a seedling into seed water permeable.
( 3 ) Seed
QUANSEN retainsupport® superabsorbent polymer seed also called seed or seed coating, it can be sowing seeds on the surface forming a layer of gel-like protective coating. Selection of Super absorbent polymers are usually s or m- particle type, or seed powder. Seed germination rate can be improved, convenient and conducive to mechanized operations. The specific method is: will mixing flour with water by 1:100 ratio mix, let stand 3 hours or so, pour the seeds after all become hydrogels full stirring, mixing evenly, put in the shade stuffy 4-6 hours Can be directly seeded or dried seeds. Super absorbent polymer seed and seed ratio is subject to product instructions for use, generally in the 1:500 or so, in maize, for example, each kg of Super absorbent polymers can be mixing corn seed 500 kg.
( 4 ) Mix fertilizer, fertilizer absorption method
Mix the fertilizer with QUANSEN retainsupport® superabsorbent can also directly. Mixed with fertilizer use can play a role in water and fertilizer. Operating method is: first use sprayers-Jet wet fertilizer, water and fertilizer by 1:10 ratio of full mix to make it even attached to each other. Is in need of attention, do not spray too much water in the fertilizer, so as to avoid chemical fertilizers knots faster, at the time of sowing plug feeding tubes if there are knots, used a shovel to smash it. Super absorbent polymer materials can also be invested in low-concentration solution of water soluble fertilizers, ensures that the Super absorbent polymer gel absorbs a certain amount of fertilizer, achieve the goal of sustained-release.
( 5 ) Of soilless culture
Soilless culture substrate for QUANSEN retainsupport® superabsorbent can also be used as , Also known as Crystal mud. It is the main type of polypropylene acid potassium class, the shape of round granules, irregular-shaped particles, colors are varied, its products are colorful. Mainly used on ornamental horticulture, cultivation of flowers with Crystal mud, suitable for display in the home or Office. Crystal mud of using method is simple, first, selected good flowers of transparent glass container, take must volume of particles Crystal mud, will particles Crystal mud with clear blisters 3-4 a hours, all sucking rose Hou, take 2/3 of Crystal mud pour glass container in the, then will roots flush clean of spent transplant in, last put remaining of 1/3 Crystal mud poured into the can. Note containers which do not have too much water, vase placed to avoid direct sunlight.
( 6 ) With seeds sown below
When the dry season to plant crops, in order to save costs, generally uses QUANSEN retainsupport® superabsorbent polymer seed sown under way, applied to planting trench (point) of QUANSEN retainsupport® superabsorbent to effectively protect crop seedlings to grow normally.
( 7 ) Strewn
Generally high cost of strewn QUANSEN retainsupport® superabsorbent can be used in planting perennial crops and lawns.
Super absorbent polymer mixed fertilizer to the soil, after absorbing water as the water is released slowly shrink, expand--contract will form a larger soil spaces, some space directly connected with the atmosphere and promote water exchange between soil and atmosphere, the respiration of the roots, but it will also cause some water loss. Application of QUANSEN retainsupport® superabsorbent in the process of expansion--contraction will also form a larger gap, but from the voids in the surface soil interval, weak water exchange with the atmosphere absorb and maintain, since it could maintain a higher moisture content. Pocketing the small contact area of water and soil, moisture holding capacity is small and too concentrated, relatively adequate inhibition of seedling in soil moisture, can result in poor soil aeration influence growth and survival. Some people think that applying superior application, the main reason is the excessive application of local soil moisture affects the normal crop emergence. Groove effect, pocketing, mixing effects of water retaining agent on soil depth distributions in different, determines the depth distribution of water layer in the soil. Application, pocketing over relatively deep water, applying relatively shallow. Application, pocketing absorb the moisture and keep not easy losing, applying the more vulnerable, with many experimental results of the Groove application, cave can increase soil moisture, promote crop growth are consistent. With spring temperatures of rebounded, soil water evaporation strongly, West southern coastal, area of soil easy has salt gathered surface, and tomatoes, crop not resistance salt, insurance agent can reduced evaporation, effective ease soil salt table set, for crop growth create a wet and low salt of soil environment, can more long time of maintained body water balance, keep growth vitality, promote root growth, and flowering fruit period suitable of soil water is high yield quality of key.
