1. SAP application scope and use method:

A. Urban gardens and green spaces (lawn, flower beds, football fields, golf courses, etc.):

The use of water-retaining agents in the northern region can make the lawn turn green 10 days earlier, and the green period is extended by about 20 days.

1. New type of lawn: Sprinkle the water-retaining agent dry powder evenly on the surface of the land, then mix it with the soil 10 cm deep on the surface, and then spread it with topsoil or fine sand (to help moisturize), and finally sprinkle the grass seeds onto the soil surface , Palladium flat suppression, pouring water (to ensure that the water-retaining agent can absorb enough water). The amount of water-retaining agent is 80 g / m2 on sandy soil, 40 g / m2 on fertile soil and 20 g / m2 on clay.

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

3. Hydraulic direct spraying: on highway slope protection, grass seed spraying on the golf course, the water-retaining agent is used in combination with grass seeds, wood fibers and adhesives in an amount of 2 to 10 grams per square meter.

4. Guest soil spraying: water-retaining agent, soil, fertilizer, etc. are mixed and sprayed on the base layer to be covered, and then the seeds are sprayed again. The amount of water-retaining agent is generally 40 g / m2, and the amount can be adjusted according to the slope of the slope, the needs of the plants, and the climatic conditions.

B. Afforestation

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

1. Seedling transplantation: dig a pit enough to accommodate the transplanted tree roots, and leave the top layer 5 cm of soil, the other soil in the tree pit is fully mixed with the water retaining agent, the amount of water retaining agent: 1 kg-2 kg per cubic meter of soil Then, fill the mixed soil into the bottom of the pit, put the trees into the pit, and then fill the surrounding soil with other mixed soil, after compaction, pour water (it can be poured several times), and then fill the soil left on the top layer Into. It is better to use the water-retaining agent as a gel after absorbing water in conditions where conditions are better.

In arid areas, the root dipping method can be used to fully absorb the water-retaining agent into a gel, add soil to make a gel slurry, wrap the mud into the roots and implant it in the pit, then fill the soil, the amount of water-retaining agent is 10-300 grams / Strain.

2. Cutting and dipping branches: the branches that need to be cut can be dipped in the water-retaining gel at 4-5cm at the base of the branches, and then evenly dipped and planted.

3. Original trees: Dig a ditch about 20 cm wide at the projection of the canopy (ditch depth depends on the distribution of the root system and requires a concentrated distribution layer of the root system), dig out the soil in the ditch and mix well with the water retaining agent (the dosage is per Cubic soil mixed with water-retaining agent dry powder 1-2 kg), backfill, pour water after solid. It is better to use the water-retaining agent as a gel after absorbing water in conditions where conditions are better.

4. Seedling transportation or flower water retention: Dip the water retention agent into a gel form with water, add the same volume of humus soil and grass ash as the gel form, adjust it to a mud shape with an appropriate amount of water, and use this mud to wrap the roots of the seedlings and flowers. It can increase the survival rate of seedlings by 20-50%.

C. Field crops

The application methods for field crops such as wheat, corn, peanut, soybean, cotton, etc. are as follows:

1. The gel formed after the seed-retaining water-retaining agent is saturated with water is called a gel. Dilute the gel 2-3 times with water and add it to the seeds that need to be mixed. Stir while adding it until it is well mixed and piles up. 4 -5 hours, the seeds can be sown without adhesion, and watered after sowing. The seed dressing amount per 0.5kg of gel is as follows: wheat is 15-20kg, corn, soybean, sorghum, peanut, cotton seed (depilling) is 20kg; millet and cotton seed (non-depilling) is 15kg. (This is the recommended seed amount, depending on the seed size and the smoothness of the seed surface.)

2. Seed soaking Place the seeds in a gel of water-retaining agent, soak for 12 hours, sow dry after sowing, pour water after sowing, the dosage is gel: seed = 1: 5-10 (usually used when sowing)

3. Coating film Soak the seeds in water before sowing. After the surface is completely moistened, sprinkle in the powder of water-retaining agent, make the surface dipped in a layer of water-retaining agent, and then spread it on cultivated land. The amount of water-retaining agent is roughly 4-5 kg ​​/ mu.

4. Dry sowing method After uniformly mixing the dry powder of water-retaining agent with chemical fertilizers, pesticides, fungicides, etc., sowing in the ditch or sowing manually with the seeding machine, and then pouring enough water. The amount of water-retaining agent is roughly 4-5 kg ​​/ mu.

D. Vegetables, economic fruits and fruits:

1. Seed dressing: 1 kg of water-retaining agent gel, add 4 kg of vegetables, melons and other seeds that need a large amount of water at the seedling stage and need to be soaked, mix evenly, pile for 1-8 hours, and sow when there is no adhesion. The water-retaining agent can also be mixed directly with the soil, and then added to the seeds that only wet the surface, and the ground is prepared in the usual way, after sowing by the traditional method, and then fully watered. For the tomatoes, green peppers and beans of the hole planting type, mix the soil in the hole with the water-retaining agent (3-5 kg ​​water-retaining agent per mu), and then fill the hole with enough water.

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

3. Root dipping: This method can also be used for seedling transplantation, that is, the soil of the root of the seedling is put into the gel body of the water-retaining agent to be dipped and transplanted, and the seedling should be poured with water.

E. Flowers:

Potted flowers: In potted flowers, mix the water-retaining agent (the dosage should be 1 ~ 2 kg / m3 soil), fertilizer and soil in proportion, then backfill it into the flower pot, after planting the flowers, fully pour water. When planting flowers, first install mixed soil to 70% full, then cover the surface with 2cm or more of soil without water retention agent.

2. Make colorful crystal gel: The water retention agent absorbs water to make a gel, add red, yellow, blue, green, purple and other colors, just like crystal, you can mix several different color crystal gels Planting different kinds of flowers in transparent vases, craft glass jars, etc., has a very good decorative effect and strong ornamental.

2. Basic usage of various main crops

Apply to the roots. Applied to the soil layer where the roots are distributed in the planting pits, any plant must expose part of the roots to this agent.

According to the season when the agent is applied or the dry and wet conditions of the plot, choose one of the following two methods: wet application method: the season or the plot with little drought and rain, apply the agent after absorbing water into a gel. u

Dry application method: apply the dry agent directly in the rainy and wet seasons or plots.

Do not let the sun shine on this agent, because ultraviolet light has a cracking effect on this agent, so neither gel nor dry agent should be spread on the ground, it should be spread in the ditch and mixed with the root soil (or mixed soil 10 (Apply after ~ 30 times), and finally cover with soil.

The "gel agent" hereinafter refers to a gel-like substance that the dry water-retaining agent puts into a certain proportion of water. For example, "a gel agent that absorbs 200 times as much water" refers to a gel obtained by putting 1 kg of dry water-retaining agent into 200 kg of water and swelling with water. Among them, "200 times" takes 1: 200 as an example, in order to calculate the dosage per acre or per plant; the specific water absorption rate can be increased or decreased according to the drought.

This agent should not be mixed with chemical fertilizers because Na ions, K ions, Cl ions and phosphate fertilizers have an antagonistic effect on the water-retaining agent. If it is indeed necessary to apply the chemical fertilizer together, do not directly mix the agent with the chemical fertilizer, but apply the chemical fertilizer to the bottom of the dug trench first, then cover the chemical fertilizer with thin soil, and then apply the agent. Can achieve the effect of labor saving and fertilizer saving.

The water-retaining agent is not a water-generating agent, and it must have a small amount of water to achieve the effect of drought resistance;

After using the "dry application method", the water must be poured in a timely manner as usual; if there is no watering condition, please use the "wet application method";

Whether it is dry application or wet application, the water-retaining agent must be mixed with the subsoil in the ditch evenly to prevent excessive concentration of water and cause rotten seeds or roots; at the same time, the distribution range of the water-retaining agent can be expanded after stirring to make the root system grow Can absorb moisture after stretching. ★ The "mu" referred to below: 667 square meters.
