Summary
The super water retention agent produced by our company through introducing Australia technology is a polymer suction material. And it can not only absorb hundreds even thousands weight of water of itself and it has also super property of water retention. If it is planted into soil, it can not only absorb the water of air and soil and it can also strongly hold a large quantity of rain and irrigation water, and then release slowly to provide for the seed and crops. So it can increase the rate of young plants, retard the time of rot, shorten the period of crops ripening and increase the quantity of the production. It is a new product for anti-drought, preventing from flood and saving irrigation water. The water in our country is very insufficient. There is often no harvest in the north of Changjiang because of lack of water. In the west, people are planting trees to prevent deserts. The water retention material is greatly needed for the harassing of sand wind in Beijing. As the experiment show, the harvest of crops will increase by 20%, 20~40% for vegetable, 20% for the survival rate of plants, if this kind of water retention material is used.
Technique Index
Appearance: white or light gray powder or particle solid. It is insoluble in water. After absorbing water, it will swell to form gel which can counteract some pressure compression.
Coefficient of water absorption: 400-500 ml/g for distilled water.
Coefficient of salt water absorption: 60-90 ml/g for 0.9% salt water.
PH: 6.5-7.0
LD50: >1000mg/kg
Performance and properties
1. This is a high molecular material having strong ability to absorb water. If it is contacted with water, it can swell to form gel in a short time. The capacity of absorption can reach above hundreds weight of itself. It can absorb rain water or irrigation water rapidly and then store it. When the crops need water, it will release moisture slowly. From this way, it can not only provide the water of plants, but also prevent water from loss, such as vaporizing, leakage and bleeding and keep the soil moisture. As the experiments has shown, the water content of earth is more than 5~15% during the period of the crops growing accordingly. 50% of water can be saved. This product can absorb, release, and supply water slowly for crops slowly.
2.It can improve the structure of earth such as particle structure, water permeability, and air permeability and thermal capacity. It make earth shrink and swell repeatedly, which leads to a lot of pore space in earth and improve air permeability and water permeability of earth, and improve the micro-organism around the root. It can also fasten the decomposition of organism to make the root absorb easily. At the same time, it promotes growing system of root and crops and improves the quality of soil to prevent soil from hardness and natronization.
3. It is stable and high efficient in all kinds of soil, crops and climates.
4. It can promote crops growing, increase the brooder rate of seed by 5~15%, and shorten the period of ripe by 1.5 to 3 days. It can also promote growing system of root.
5. Saving agricultural pesticide and fertilizer, if it is mixed with agricultural pesticide and fertilizer. It can also store agriculture pesticide and fertilizer and then release slowly. In this way, the efficiency of agriculture pesticide and fertilizer will be increased by loss of vaporization, leakage and bleeding.
6. It is nontoxic, harmless, non-by-effect, which is checked by organization of environmental monitoring and department so health. There is no contamination to environment and crops during the whole period of use.
7. This product is fit in our country and the price is low (only about 1/10 of the import price). It is widely and long used. It can be used for 23 years repeatedly.
Usage
1. Crops
The following methods are fit for crops such as wheat, corn, peanut, soybean and cotton etc.
1) Stirring seed
After the water retention agent sucked enough water is called gel. Dilute gel with water (23:1). Then add the seeds into it. Stirring the seeds evenly. Keep it for 4 to 5 hours. The seeds can be planted when they are not linking together any more. Then spray enough water on the seeds. The quantity of seeds mixed with per 0.5kg water retention agents are shown as below: 15-20kg for wheat, 20kg cotton, soybean, broomcorn, peanut, cotton seeds, and 15kg for corn, cotton seeds.( the amount is only suggested. The actual amount should depend on the greatness and smoothness of the seed)
2) Immersing seed
Immerse the seeds into the gel of water retention agent for 12 hours. Plant them after drying them. Then spray enough water. The proportion of water retention agent and water is 1:5-10.
3) Coating film
Before planting, immerse the seeds into water till the surface of the seeds has been wet thoroughly. Then spray the powder of water retention agent. By this way, a layer of water retention agent is formed on the surface of the seeds. Then scatter it into the field. The dosage of water retention agent is 45kg per mo.
4) Planting the seeds directly
Mix the water retention agent powder with fertilizer, germicide. Plant them with the planting machine or by hand. Then spray the water. The usage of the water retention agent is about 4-5 kg per mo.

Examples:
In Jiaonan City of Shandong Province, the production of the wheat planted by Tufei Zhan has increased by 27% (4kg water retention agent per mo); In Wusi farm of Qingdao City, the production of summer corn has increased by 35.8% (4kg water retention agent per mo).
Vegetables
Plod the field by usual way. Mix the soil with the water retention agent by 10-15g/m3. The height of the soil mixed with the agent is 30cm. Spray enough water after planting the seeds by traditional way. Mix the soil from the hole with water retention agent enough (10kg water retention agent per mo) and refill the soil into the hole when planting the tomato, green pepper and potato etc.
