How to use Potassium Polyacrylate - Water Retaining Gel?

April 30, 2021

What is Potassium Polyacrylate

The water-retaining agent is a kind of organic polymer polyacrylate with a three-dimensional network structure.

It has the unique functions of absorbing water, storing water, releasing water, and repeating the cycle.

There are no undesirable substances, non-toxic and harmless to the environment and plants, no loss with rain, and natural degradation after many years, reducing to ammonium nitrogen, water, and a small number of potassium ions, effectively improving the soil.


Precautions

1. Do not let the sunshine on the water-retaining agent, because ultraviolet rays have a cracking effect on the water-retaining agent. It must be spread in the ditch and mixed with the root-soil (Or mix the soil 10-30 times before applying it), and finally cover with soil;

2. The water-retaining agent can be directly mixed with some fertilizers, such as urea, farm manure, organic fertilizer, bacterial fertilizer, etc .; water-soluble fertilizer can also be dissolved in water, and then the solution is absorbed into the agent, which becomes a fertilizer Release agent.

3. The water-retaining agent should not be directly mixed with some fertilizers, because Na (sodium) ions, K (potassium) ions, C1 (chlorine) ions, Ca (calcium) ions, and phosphate fertilizer have an antagonistic effect on the water-retaining agent, which will The multiple of water absorption drops sharply and even loses its effectiveness;

If it is indeed necessary to apply the fertilizer together, the following methods can be used: (1) staggered release: the fertilizer and water-retaining agent are staggered and placed in different trenches; (2) layered release: spread a layer between the water-retaining agent and the fertilizer Layer 5 ~ 10 cm of soil.
①Apply water-retaining agent at the bottom of the pit, mix well with the pit soil, then cover with a layer of soil, then apply a chemical fertilizer, cover the soil after planting, and water it in time;
②First apply chemical fertilizer to the bottom of the pit, then cover with a layer of soil, then apply water retention agent, mix well with the soil, cover the soil after planting, and water it in time.

4. If lime is used to disinfect and improve the acidity of the soil, be sure to sprinkle hydrated lime into the bottom of the pit, then cover with a layer of soil, then apply water retention agent and mix with the soil, cover the soil after planting and water it in time;

5. Not all water-retaining agents can be used in agricultural production. Super-absorbent resins for sanitary purposes are forbidden in agricultural and forestry production. Hygienic water-absorbent resins can absorb thousands of times of water absorption, but are easily degradable and have poor water release capacity reuse;

6. The water-retaining agent should be kept away from light, keep dry, and pay attention to moisture. The water-retaining agent sees light for a long time, it will shorten its lifespan obviously. The water-retaining agent can absorb moisture in the air, and some bacteria will make it moldy and deteriorate, so the water-retaining agents are all sealed.

7. Try to avoid using metal containers to hold the water-retaining agent.

8. When the water-retaining agent is immersed into a gel, the water-retaining agent should be poured slowly into the water and continuously stirred to avoid agglomeration of the water-retaining agent in the water and affect the water absorption speed.


Principles of using

1. The water-retaining agent is not a water-generating agent, and must absorb water in the presence of water to achieve the effect of water retention and drought resistance;

2. The water-retaining agent must be applied to the soil layer where the roots of the plants are distributed so that the roots of some plants can be exposed to the agent;

3. The water-retaining agent should be evenly mixed with the soil: the water-retaining agent must be mixed with the subsoil in the ditch evenly to prevent excessive concentration of water from affecting the soil permeability and causing rotten seeds or roots.

The soil mixed with a water-retaining agent can improve its breathability and water-holding performance, and it can expand the distribution range of the water-retaining agent after stirring so that the root system can absorb water after it grows and extends;

4. Choose the water-retaining agent according to the size of the plant. Small plants (large particles) should be used for large plants, and large mesh (small particles) should be used for small plants. Use 80 ~ 100 mesh water-retaining agent for seed dressing, coating, and dipping roots.

5. Factors determining the dosage:

  • Plant type: The plant type that prefers moisture is larger than the drought-tolerant plant.
  • Climatic conditions: The amount used in drought conditions is greater than usual.
  • Soil properties: sandy soil is used more than loam, and loam is used more than clay. In the case of drought climatic conditions, the use of drought-tolerant plants on sandy soils is double the usual amount.
  • The amount and method of a water-retaining agent should be adjusted according to the actual situation on the basis of these instructions.

Two ways to use

  1. Wet application method: apply the water-retaining agent dry product into a gel, apply it, mix it with the soil and plant the overlying soil, then water it once. This method is generally used in dry seasons or plots;
  2. Dry application method: The dry product of the water-retaining agent is directly applied and mixed well with soil, and water is poured in time after planting the cover soil. This method is generally used in rainy and wet seasons or plots; in the total use effect, the water retention effect of applying the water retention agent using the wet application method is better than that using the dry application method.

Effectiveness

1. Reduce irrigation costs. The water-retaining agent has a strong water absorption function, a high water absorption rate, and can effectively store water. After repeated cycles, the application of agricultural and forestry water-retaining agents can reduce the number of waterings by more than 70% and save irrigation costs by more than 50%. It can save water and save labor in the year, and drought resistance can be greatly reduced during drought.

2. Guaranteed output. The water-retaining agent can increase the germination rate of seeds and the survival rate of seedlings transplanted, up to 98%, and shorten the slow seedling period, enhance stress resistance, maintain soil constant humidity, continuous and balanced water supply, effectively improve the fruit setting rate, reduce the bursting fruit cracking, improve fruit quality.

3. Improve the soil. The water-retaining agent can repeatedly absorb water and release water. In the process of shrinkage and expansion, the soil forms a porous structure of the pellet, which improves the permeability of the soil, is beneficial to the growth of plant roots and microorganisms, and enhances the ability of the soil to retain water and fertilizer The role of soil improvement.

4. Keeping fertilizer and increasing production. The water-retaining agent will absorb and store the nutrients in the water-soluble fertilizer together with water. When the water-retaining agent releases water, it will be slowly released for crop utilization, reducing the loss of fertilizer, prolonging the period of fertilizer efficiency, and improving fertilizer utilization.

5. Safety and environmental protection. The water-retaining agent is an environmentally friendly product. The product conforms to the relevant industry standards through toxicological identification by authoritative institutions. It has no undesirable substances in the released water, is non-toxic and harmless to the environment and plants, can be naturally degraded, and is reduced to ammonium nitrogen and water. And a small number of potassium ions. Widely used in agricultural and forestry crops, landscaping and flowers, and other fields.


HOW TO USE

Perennial plants: fruit, tea, forest, banana, mulberry, sugarcane, medicinal materials, bamboo shoots

Dip the root of the hydrogel mixed with the fine-grained water-retaining agent, and add the large-grained gelling agent after absorbing the water in the planting hole.

Dipping roots can prevent the seedlings from dehydrating during planting, and the hydrogels for basic application provide the closest and most effective water source for absorption during the critical period of seedling rooting, shortening the seedling delay period.

A. Transplanting
1. Dip root

Use a water-retaining agent (80 ~ 100 mesh) and fine soil (if the transplanted seedlings have a certain amount of soil in the root system when dipping the root, you don’t need to add fine soil) at a ratio of 1: 5 ~ 10 and put it into a large non-metallic container.

In order to make the water-retaining agent have enough time to absorb water, add about 100 ~ 150 times of water (the rooting powder can be added at the same time) 6-20 hours before dipping the root (the longer the time, the better the effect), mix and form a gel The agent or colloidal mud can then be used to dip roots of seedlings for afforestation.

When the seedlings are dipped into roots, they can be single or multiple plants, and no more than 50 plants at most. It is necessary to ensure that the roots of the seedlings are fully immersed in the gel or colloidal mud to fully dipped the roots.

2. Seedling cutting seedling raising: dipping root + base using

Wet application method: After mixing the matrix soil in the seedling bed with a gel agent that accounts for 1/5 ~ 3/5 of the total mass of the matrix soil, mix well, and level the seedling bed, and then cover it with a layer of fine soil. Dip the roots of the branches into roots and cut them in the seedling bed, then just water them regularly.

Dry application method: After mixing 5 ~ 15g of dry water-retaining agent per square meter on the seedbed, the seedbed should be leveled. Then cover it with a layer of fine soil, soak the roots of the branches and cut them into the seedling bed, and immediately water them.

3. Seedling cultivation

Cell-building method: mix 1/5 ~ 3 / dike-strand agent into the culture medium, mix it evenly, and bag it, then pour water according to the routine, then you can plant, bud, and transplant seedlings;

Dry application method: Mixing 0.1% ~ 0.3% of the total mass of the medium quality into the medium quality, the dry product of the water retention agent is mixed evenly, bagged, and immediately poured through the water, so that the seeds can be planted, budded, transplanted and seedlings raised.

4. Planting base using

Wet application method: The gel is applied into the dug hole, then mix well with the fine soil at the bottom of the hole, then move into the rooted seedlings, cover the soil into a concave shape (in order to collect rainwater), and then immediately root water once.

Dry application method: Sprinkle the dry product directly into the dug hole, and then mix well with the fine soil at the bottom of the hole, and then move into the rooted sapling, cover the soil into a concave shape (in order to collect water), and immediately pour enough water.

B. Adult tree using

1. The band-shaped furrow is applied according to the topography and the plant row spacing, choose the appropriate plant spacing or row spacing, the canopy drip line (geotherapy to which the crop root grows) to dig trenches 40 cm wide and 40 cm deep to the plant root distribution layer.

Application method

Wet application method: apply gel into the dug trench, mix well with the fine soil in the trench according to the ratio of 1: 5, cover the soil (not stepped on) into a concave shape (to collect rainwater), water once according to the routine.

Dry application method: Sprinkle the dry product directly into the dug trench, mix it with the fine soil in the trench according to the ratio of 1: 1000, cover the soil (not stepped on) into a concave shape (to collect water), and immediately pour water.

2. Strip grooves are applied on one or both sides of the plant to dig a ditch with a length of 60em, a width of 40cm, and a depth of 60cm along the crown drip line (where the crop roots grow).

The application method is the same as the band-shaped furrow application, and the wet application method and the dry application method can be used.

3. If water retention agent and fertilizer are applied together, there are three application methods:

(1)Staggering method. This method can avoid the effect of chemical fertilizers on the water-absorbing and water-retaining effect of the water-retaining agent and at the same time take into account that the plant can not only absorb the nutrients of the fertilizer but also the water released by the water-retaining agent.

Slot ditch method 1: ditch the middle of the two plants with a water-retaining agent and fertilizer on the other.

Staggering method 2: Apply water-retaining agent on one side of the plant and apply fertilizer on the other side.

(2) The water-retaining agent and the fertilizer are applied in the same ditch, and the application method of the water-retaining agent on the top of the fertilizer can be used when paying attention to its water-retaining function.

(3) The water-retaining agent and the fertilizer are applied in the same ditch, and the application method of fertilizer on the top of the water-retaining agent can be used when paying attention to its fertilizer retention function.

Note: The depth of the ditch is generally more than 40cm, because the water-retaining agent will be decomposed by microorganisms, and the microorganisms are more active towards the ground, which accelerates the decomposition rate of the water-retaining agent. The deeper the agent is buried, the deeper the roots of the plant are, and the stronger and more developed the root system of the tree is, the better the effect is.

If you pay attention to the effect of water retention, use the wet application method; if you consider the effect of fertilizer retention, use the dry application method.

C. Water retention agent dosage

1. Root dipping: Use an 80 ~ 100 mesh water-retaining agent to dip the roots. According to the size of the seedling root system, treat about 500 ~ 2000 seedlings per 1 kg of the dry water-retaining agent.

2. Seedling cutting nursery: According to the plant size and cutting density, apply 5 ~ 15g / ㎡ of water-retaining agent dry product and 1 ~ 3kg / ㎡ gelling agent.

3. Cultivation of seedlings in culture bags: In general, the amount of dried water-retaining agent is 0.1% of the matrix soil of the culture bag, and the gelling agent is about 1/5 of the matrix soil of the culture bag.

4. Planting-based application: the amount of water-retaining agent dry product is generally 0.1% of the dry soil of planting tree hole. According to the experiment, if 2 to 3-year-old conifer seedlings are used, the tree hole size is 30cmx30cmx30cm, and the amount of water-retaining agent is 30g per tree; if 1 to 2-year broadleaf tree seedlings are used, the tree hole size is 40cmx40cmx40cm, the amount of water-retaining agent is 75g each; 2-year economic forest Seedlings, using 50cmx50cmx50cm tree planting hole, the amount of water retention agent is 150g per plant.
