I . Performance and characteristics

 

 

At present, most of the water retention agents on the market are disposable products, and the SV-PBS water retention agent produced by our company has the effect of absorbing water and nutrients for many times, and is an energy-saving and environmentally friendly product, with low price and affordability.

 

 

 

(1) Water retention and water saving

 

 

This product is a polymer material with super water absorption ability, and the ability to repeatedly absorb pure water can reach hundreds or even thousands of times of its own weight, and the ability to absorb irrigation water is also 100-200 times. The finer the particles, the stronger the water absorption capacity and the faster the speed. The water-retaining agent can quickly absorb rainwater, irrigation water and store it, and release it slowly when the plant needs it, which can not only ensure the water required for the normal growth of the plant, but also reduce the loss of water and nutrients caused by evaporation, leakage and loss, and ensure that the plant uses more rainwater and irrigation water. Experiments have proved that the soil moisture content of plants is 5-15% higher than that of the control during the whole growth period, which can save more than 50% of water, which is equivalent to more than doubling the rainfall, so it can greatly improve the survival rate and yield of crops in arid areas.

 

 

(2) Improve the permeability of the soil

 

 

The water-retaining agent can repeatedly release water and shrink and absorb water in the soil thousands of times, causing a large number of pores to the soil, improving the air permeability and permeability of the soil, improving the rhizosphere environment, and also enhancing the activities of rhizosphere microorganisms, accelerating the decomposition of organic minerals around the rhizosphere, which is conducive to root absorption, promoting the growth and development of roots and plants, improving the soil substrate, and preventing soil compaction and salinization.

 

 

(3) Promote growth

 

 

It can increase the germination rate of seeds by 5-15%, advance the emergence of seedlings by 1.5-3 days, and promote the growth of the root system, so that the plant root system is deeper and more developed.

 

(4) Fertilizer absorption and fertilizer retention

 

 

When applying the water-retaining agent, it can be mixed with a large number of water-soluble fertilizers, and at the same time it can absorb and store fertilizers and pesticides together to form a "miniature water and fertilizer reservoir", and then slowly release the water and nutrients in the dry season, thereby improving the fertilizer utilization rate, reducing fertilizer loss, increasing fertilizer efficiency, saving more than 30% of fertilizer, and reducing the pollution of soil and groundwater caused by fertilizer leakage (the same principle of pesticides).

 

 

(5) Highly environmentally friendly

 

 

The water retention agent is non-toxic, harmless, and has no side effects, and has been tested by environmental monitoring agencies and health and epidemic prevention departments, and the use of water retention agents does not have any pollution to the environment and crops, and after 3-5 years, it can finally decompose into ammonia, carbon dioxide and water.

 

 

II．Second, the application scope and use of water retention agent

 

 

(1) Urban landscaping (lawns, flower beds, football fields, golf courses, etc.):

 

 

The use of water-retaining agents in northern regions can make the turf regreen 10 days earlier and the green period longer by about 20 days.

 

 

1. Newly planted lawn: sprinkle the dry powder of the water-retaining agent evenly on the surface of the land, then mix it well with the 10 cm deep soil on the surface, then spread the topsoil or fine sand (help to moisturize), and finally sprinkle the grass seeds into the soil surface, palladium flat suppression, and water thoroughly (to ensure that the water-retaining agent can absorb enough water). The dosage of water retention agent is 80 g/m2 on sand, 40 g/m2 for loamy soil, and 20 g/m2 for clay.

 

 

2. Transplant the lawn: evenly sprinkle a layer of water-retaining agent dry powder on the soil surface of the lawn to be paved, mix well with the soil 10 cm deep on the surface, and then spread the turf, and then pour a large amount of water, the dosage is the same as above.

 

 

3. Hydraulic direct spraying: In highway slope protection and golf course grass seed spraying, the water-retaining agent is combined with grass seeds, wood fibers and adhesives, and the dosage is 2~10 grams per square meter.

 

4. Soil spraying: Spray the water-retaining agent with soil and fertilizer on the base layer that needs to be covered, and then spray the seeds for the second time. The dosage of water retention agent is generally 40 g/m², and the dosage can be adjusted according to the slope of the slope, the needs of plants, and different climatic conditions.

 

 

(2) Afforestation

 

It can be used for the cultivation of trees and shrubs. The water-retaining agent can effectively reduce transplantation mortality, help root development, promote plant growth, and increase the survival rate by 20%. The effect is more significant when used in barren mountain afforestation in arid areas.

 

 

1. Seedling transplantation:

 

 

Dig a pit that is enough to transplant tree roots, leave the top layer of 5 cm soil, the other soil in the tree pit is fully mixed with the water retention agent, the amount of water retention agent is 1-2 kg / cubic meter, and then fill the mixed soil into the bottom of the pit, put the tree into the pit, and then fill the other mixed soil around, after compaction, water thoroughly (can be watered several times), and then fill the top layer of soil left. Where conditions permit, it is best to use the water retention agent after absorbing water and forming a gel, and the effect is better.

In arid areas, the root dipping method can be used to fully absorb the water retention agent into a gel body, add soil to make a gel slurry, wrap the mud into the pit after wrapping the root system, and then fill the soil, and the dosage of the water retention agent is 10-300 grams per plant.

 

 

2. Cuttings and dipping branches:

 

 

For the branches that need to be cuttings, the water retention agent gel can be dipped in the gel at the base of the branch 4-5cm, and the planting can be planted after dipping evenly.

 

 

 

 

 

 

 

 

3. Existing trees

 

 

Dig a ditch about 20 cm wide at the crown projection (the depth of the ditch depends on the distribution of the root system, and it is required to reach the concentrated distribution layer of the root system), dig out the soil in the ditch and mix it with the water-retaining agent (the dosage is 1-2 kg per cubic meter of soil mixed with the dry powder of the water-retaining agent) and then backfill, and water thoroughly after being solid. Where conditions permit, it is best to use the water retention agent after absorbing water and forming a gel, and the effect is better.

 

 

4. Seedling transportation or flower water retention

 

 

The water-retaining agent is soaked into a gel form with water, and then the same volume of humus and plant ash as the gel is added, and the appropriate amount of water is adjusted into a mud shape, and the root system of seedlings and flowers is wrapped with this mud, which can improve the survival rate of seedlings by 20-50%.

 

 

(III) Field crops

 

 

The use of field crops such as wheat, corn, peanuts, soybeans, cotton, etc. is as follows:

 

1. Seed dressing: The colloid formed after the water retention agent absorbs enough water is called the gel, dilute the gel with water 2-3 times, add it to the seeds that need to be dressed, stir while adding until it is mixed well, pile it for 4-5 hours, the seeds can be sown without adhesion, and water thoroughly after sowing. The amount of seed dressing per 0.5kg of gel is as follows: 15-20kg for wheat, 20kg for corn, soybean, sorghum, peanut and cotton seed (delinted); Millet and cotton seeds (not depiled) are 15kg (here is the recommended seed amount, depending on the size of the seed and the smoothness of the seed surface).

 

 

2. Soaking seeds: Put the seeds into the water-retaining agent gel, soak the seeds for 12 hours, sow them after drying, and

water them thoroughly after sowing, and the dosage is the gel: seeds = 1:5-10 (this method is generally used when sowing on demand).

 

 

3. Coating film: Before sowing, soak the seeds in water, and after the surface is completely wet, sprinkle into the powder of the water-retaining agent, so that the surface is stained with a layer of water-retaining agent, and then sow on the cultivated land. The dosage of water retention agent is roughly 4-5 kg/mu.

 

 

4. Dry sowing method: After mixing the dry powder of the water-retaining agent with chemical fertilizers, pesticides, fungicides, etc., it is sown in the ditch or manually sown with the seeder, and then watered enough. The dosage of water retention agent is roughly 4-5 kg/mu.

 

 

4) Vegetables, economic melons and fruits:

 

 

1. Seed dressing: 1 kg of water-retaining agent gel, add 4 kg of vegetables, melons and other seeds that need to be soaked in water at the seedling stage, mix evenly, pile up for 1-8 hours, and sow seeds when there is no adhesion. It is also possible to mix the water-retaining agent directly with the soil, and then add it to the seeds with only the moist surface, prepare the land in the usual way, and after sowing with the traditional method, water it fully. For tomatoes, green peppers and beans of hole plants, the soil in the hole and the water retention agent (3-5 kg of water retention agent per mu) are fully mixed and then backfilled with enough water in the hole.

 

 

2. Seedbed seedling raising: according to the amount of 1-2 kg/mu of water-retaining agent, add water to form a gel and sprinkle it on the seedling soil, mix it with the upper layer of soil and sow it, and finally cover the surface with fine soil without water-retaining agent.

 

 

3. Dipping roots: Seedling transplantation can also be used in this method, that is, the roots of the seedlings are put into the gel of the water-retaining agent and dipped in transplantation, and the seedlings should be watered thoroughly after planting.

 

 

(5) Flowers

 

 

1. Potted flowers: In potted flowers, the water-retaining agent (the dosage should be 1-2 kg/cubic meter of soil), fertilizer and soil are mixed in proportion, backfilled into the flower pot, and after the flowers are planted, they are fully watered. When planting flowers, first fill the mixed soil to 7 full, and then cover the surface with more than 2 cm of soil without water-retaining agent.

 

 

2. Make colorful crystal gel: after the water retention agent absorbs water, make a gel, add red, yellow, blue, green, purple and other colors, similar to crystal, you can mix several different colors of crystal gel in layers in transparent vases, craft glass jars and other containers, and then plant different varieties of flowers, with a good decorative effect and strong ornamentality.

 

 

Note: Various types of customized water retention agents can be produced.
