How to use super absorbent polymer in gardens, trees, and crop

The repeated absorption of pure water can reach hundreds or even thousands of times of its own weight.

The absorption capacity of irrigation water is also 100-200 times.The finer the particles, the stronger the water absorption capacity, the faster the speed.Water retaining agent can quickly absorb rainwater, irrigation water and save it, when the plant needs, and release it slowly, which can not only ensure the water needed for the normal growth of the plant, but also reduce the loss of water and nutrients caused by evaporation, leakage and loss, so that the plant can use more rain and irrigation water

.The experiment shows that the soil water content in the whole growing period of plants is 5-15% higher than that of the control, which can save more than 50% of water, which is equivalent to more than double the rainfall, so it can greatly improve the survival rate and yield of crops in dry areas.

Application scope and application method of super absorbent polymer (water retention agent)

A. urban green gardens (lawns, flower beds, football fields, golf courses, etc.) :The use of water retention agent in northern areas can make the lawn green 10 days earlier, green period extended about 20 days.

1. New lawn: evenly sprinkle the water-retaining agent dry powder on the surface of the soil, and then mix it with the soil 10cm deep. Then spread the topsoil or fine sand (to help moisturize).The dosage of water retaining agent is 80 g/m2 of sand, 40 g/m2 of fertile soil and 20 g/m2 of clay.

2. Lawn transplantation: evenly sprinkle a layer of water-retaining agent dry powder on the soil surface of the plant-ready lawn, mix it with the soil 10cm deep on the surface, then lay the turf, and then pour a large amount of water, the dosage is the same as above.

3. Hydraulic direct spraying: on the spraying of grass seeds for highway slope protection and golf course, combine the water-holding agent with grass seeds, wood fibers and adhesives. The dosage is 2~10 grams per square meter.

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

B. afforestation:It can be used for cultivation of trees and shrubs.Water retaining agent can effectively reduce the transplant mortality, help root development, promote plant growth, increase the survival rate of 20%.The results are more significant in afforestation of barren mountains in arid areas

.1. Seedling transplantation:Dig a enough room for transplanting the pit of the root, will leave out the top 5 cm soil, buffalos in other soil mixing fully with water retention agent, water retention agent dosage: in 1 kg to 2 kg per cubic meter of soil, and soil mixture to fill in the bottom of the pit will be spanning tree into the pit, then other mixed soil fill in four weeks, after compaction, water flooding (can sprinkle a few more times), then fill in the top level to set aside the soi

l.Conditional place had better be to hold water agent to absorb full water to show gel-like hind use, the effect is better.In arid areas, the root method can be used to fully absorb enough water to form a gel, and then add soil to make a gel mud. After the mud is wrapped around the root system, it is inserted into the pit and then filled with soil. The dosage of water retention agent is 10-300 grams/plant

.2. Cutting and dipping branch:To need cuttings of branches and tendrils can be dipped in the base of branches and tendrils 4-5cm dip water retention agent gel, dip evenly after planting.

3. Original trees:Dig a trench about 20cm wide at the projection of the tree crown (the depth of the trench 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 trench and mix it with the water retaining agent (the dosage is 1-2 kg per cubic meter of soil mixing water retaining agent dry powder), then backfill it, and pour water permeable.Conditional place had better be to hold water agent to absorb full water to show gel-like hind use, the effect is better.

4. Seedling transportation or flower water retention:The survival rate of seedlings and flowers can be increased by 20-50% by immerging the water-retaining agent in water and adding the same volume of humus and plant ash as the gel and mixing appropriate amount of water into the mud.C. field cropsFor field crops such as wheat, corn, peanut, soybean and cotton, the usage methods are as follows:

1. The gel formed by mixing seed water retention agent after absorption and filling of water is called gel, dilute the gel with water 2-3 times, add to the seeds to be mixed, add while stirring, until mixing, pile up for 4-5 hours, the seeds can be seeded without adhesion, after sowing water permeable.The seed mixing amount per 0.5kg of gel is as follows: 15-20kg for wheat, 20kg for corn, soybean, sorghum, peanut and cotton seeds (deflexing);Millet and cotton seeds (not de-flexed) are 15kg.(here is the recommended amount, depending on seed size and seed surface smoothness.)2. Soak the seeds into the water-retaining agent gel, soak the seeds for 12 hours, sow them after drying, pour water through after sowing, and use the amount of gel: seeds = 1:5-10 (this method is generally used when sowing on demand)3. Before coating and sowing, first soak the seeds in water. After the surface is completely wet, sprinkle the seeds into the powder of water retention agent to coat the surface with a layer of water retention agent.The dosage of water retention agent is about 4-5 kg/mu.

4. Dry seeding method: after evenly mixing the water-retaining agent dry powder with chemical fertilizer, pesticide and fungicide, sow it in the ditch with the seeding machine or artificial seeding, and then pour enough water.The dosage of water retention agent is about 4-5 kg/mu.D. vegetables and fruits:

1. Seed mixing: 1 kg of water-retaining agent gel, add 4 kg of vegetables, melons and other seeds that need more water at seedling stage and need to be soaked into the mixture evenly, pile up for 1-8 hours, then sow without adhesion.You can also mix the water retaining agent directly with the soil and then add it to the seeds with only a wet surface.For the tomatoes, green peppers and beans planted in the hole, the soil in the hole and water retention agent (3-5 kg per mu of water retention agent) fully mix well after backfilling the hole with sufficient water can be.

2. Seedling bed cultivation: according to the dosage of water-retaining agent of 1-2 kg/mu, add water to form gel and sprinkle on the soil for seedling cultivation, mix with the upper soil and sow, and finally cover the surface with fine soil without water-retaining agent.

3 dip roots: seedling transplantation can also be used this method, that is, the root of the seedlings to the soil into the water retention agent in the gel dip transplantation, seedlings should be watered after planting.E. flowers:

1. Potted flowers: in potted flowers, mix water retaining agent (dosage should be 1 ~ 2 kg/m3 of soil), fertilizer and soil in proportion, then fill back into the flowerpot.When transplanting flowers, first fill mixed soil to 70% full, and then cover the surface with soil containing no water retaining agent above 2cm.

2. Made of colorful crystal gel, water retention agent, water absorption is made after gel with red, yellow, blue, green, violet wait for a variety of colors, like crystal, can take several different color crystal gel layer mixed loading in a transparent vase, craft glass container, then planted in different varieties of flowers, have very good adornment effect and strong appreciation
