Based on the projection of the canopy, dig a 20-30cm wide annular ditch or strip ditch along its projected edge, and the depth is based on the exposed part of the root system (about 30-50cm). Mix the water-retaining agent with fine soil or fertilizer evenly and then apply it. The middle and lower part of the ditch shall be filled with soil for irrigation. Application rate: for young trees: 20-80 g/plant; mature trees: 80-200g/plant.

It is suitable for apple, cherry, jujube, pear, peach, walnut and other fruit trees.

•Dip the roots

Mix the water-retaining agent and water in a ratio of 1:100-150 to make a gel, or add loess to make a slurry, soak the roots of the seedlings in the gel for 3-5 seconds, and plant them with the dip. For seedling transplanting, it is best to wrap the seedlings with plastic film when transporting them.

•Hole application

After mixing the water-retaining agent with most of the soil dug out of the tree hole, it is divided into two parts and applied into the tree hole. The first part is applied to the bottom of the hole. After placing the seedlings, the remaining mixed soil is backfilled, compacted and watered. It is suitable for transplanting fruit trees and saplings of green trees. Application rate: DBH 2-4cm: 20-30g/plant; DBH 4-5cm: 50-70g/plant; DBH 6-7cm: 80-100g/plant; adult tree: 100-200g/plant.

•Application in new turf

First mix the SAP with fine dry soil in a ratio of 1:5-10 and spread it evenly on the soil surface, then turn it into the soil layer about 5-10cm deep, then sow seeds or plant turf, and water it thoroughly. Application rate: sandy soil: 40-60g/ m2; loam soil: 20-40 g/ m2.

•Existing turf applications

First, dig up the turf in pieces and set it aside, spread a layer of SAP evenly on the soil surface under the turf (mix it with the fine dry soil), then plant the dug turf back to the original place, and then water it thoroughly. Application rate: sandy soil: 40-60g/ m2; loam soil: 20-40 g/ m2.

1. Seed treatment

Mix seed with 0.5%-1.0% SAP water gel, and sow after drying.

2. Hole application

Mix the SAP and fine dry soil at a ratio of 1:5-10 (or mix with fertilizer), and evenly apply it into the planting hole with a depth of 10-20cm, then cover with soil and water, and the application rate: 30-75 kg/ Ha. It is suitable for tomato, pepper, watermelon, potato, sweet potato and other hole crops.

3. Ditching

Mix the SAP and fine dry soil in a ratio of 1:5-10 (or mix with fertilizer), and evenly apply it into a 10-20cm planting ditch. Application rate: 30-75 kg/ Ha. It is suitable for row crops such as flue-cured tobacco, peanut, rape, radish, wheat, cotton and sorghum.

4. Spray

Mix the SAP with fine dry soil (or mix with fertilizer) at a ratio of 1:5-10, spray it on the surface of the soil, and then turn it into the soil layer about 5-10cm deep, water it thoroughly, and then Sow the seeds. Application rate : 90-150 kg/Ha. Suitable for sowing crops such as lettuce and chrysanthemum.

Toxicology and environmental safety tests have proved that there is no toxic residue, will not pollute the environment, and can be naturally degraded.

The pH value is about 6.0-8.0, which will not cause soil salinization, and can also prevent soil salinization;

Improve soil structure (agglomerate structure, water permeability, air permeability, heat capacity, etc.)

The repeated shrinkage and absorption of the water-retaining agent cause a large number of pores in the soil, improve the air permeability and water permeability of the soil, and improve the plant rhizosphere environment.

The decomposition of minerals is conducive to root absorption, promotes the growth and development of roots and plants, improves the soil matrix, and prevents soil compaction and salinization.

After the fertilizer is dissolved in water, it can also be absorbed and stored by the SAP.

The utilization rate of fertilizers for now is only around 35%.

The use of SAP can reduce the loss of fertilizers and greatly improve the utilization rate of fertilizers.

The SAP is working as water-retaining agent and is applied to the root system of the plant.

After rainfall or irrigation, SAP absorbs and preserves the excess water in the soil, including water-soluble fertilizers, to form a large number of underground “mini-reservoirs”, which are slowly released when the plants need it.

In this way, it can not only ensure the water required for the normal growth of plants, but also prevent the water from being wasted due to evaporation, leakage and loss, and keep the soil moist for a long time.

It can absorb and release water repeatedly, which can be used by plants slowly.
