Water-retaining agent makes moisture content be saved in for a long time in water-retaining agent because of water absorbing capacity higher than soil, and the water absorbing capacity of root system of plant is more than protecting
The water absorbing capacity of water preparation, can absorb moisture content from water-retaining agent.Water-retaining agent is widely used in greening and the agricultural water conservation of arid area.
The method of application of water-retaining agent has dry application and wet executes two kinds.
Dry application is that the water-retaining agent not absorbed water directly is used with mixing with soil, waits competence exertion effect after period water suction of watering or rain.
First dry application has the disadvantage in that, if being used for planting trees, general watering time is the shortest, only a few minutes, and the water-retaining agent of dry application is inhaled
The water time is the shortest, causes water-retaining agent fully to absorb water, and water retaining efficiency cannot give full play to；Secondly, it is compacted after dry application
Influence To Soil, after water-retaining agent water suction, expansion space is limited, also affects the soaking effect of water-retaining agent；Again, after water-retaining agent water suction
Volumetric expansion, frequently results in soil and loosens, affect stablizing of novel species seedling.
Wet executing is to use after water-retaining agent absorbs water.Conventional wet executes the shortcoming of mode: wet executing must provide for water source and soak water-retaining agent
Container, generally utilizes bigger container to be first dipped to water-retaining agent inhale water saturated gel near water source, transports to job site
Use, but after water-retaining agent imbibition, volume and weight increases hundred times, is greatly increased the workload of carrying.Can also directly by
Water is guided to job site and is used container to soak, but also to wait certain soak time, affects job schedule, also when using in a large number
Purchase, carry substantial amounts of soaking container.
Therefore, from application effect, the wet effect of executing of water-retaining agent is better than dry application, but uses wet applying method Chang Shoushui when field is used
The restriction of source, water-retaining agent soaking container etc., the method being typically only capable to use dry application.The water-retaining agent wet applying method that absorbs water in the rain is the most permissible
Solving water source and the restricted problem of soaking container, can play again the wet advantage executed, improve soil moisture content, the tree planting initial stage is Seedling
Wood provides necessary moisture content, improves survival rate.

Detailed description of the invention
Following example will the present invention is further illustrated in conjunction with accompanying drawing.
The wet applying method that water-retaining agent absorbs water in the rain is to be sprinkling upon in advance on soil by water-retaining agent, slowly drinks up the rain time rainy, less
Rainfall ensures that water-retaining agent is fully absorbed water.
During for planting trees, watching the weather forecast of locality, first dug by hole before raining, the soil dug out is placed in the one of hole
Side, if hillside fields, is then positioned over downside, it is ensured that when raining, periphery rainwater flows in cave as far as possible.Then water-retaining agent is uniformly spread
In plant pit, water-retaining agent should avoid piling up one piece, spreads out as far as possible and makes thinner to strengthen the area accepting raindrop, improves water-taking efficiency,
When waiting rainy, water-retaining agent fully absorbs rainwater, just can plant trees after volumetric expansion.
If desired use base manure, first in plant pit, insert base manure, then water-retaining agent is uniformly sprinkling upon on base manure, method ibid, with
Being beneficial to water-retaining agent and directly absorb rainfall, also allow for the water-retaining agent after water suction and mix with planting soil, after rainfall, water-retaining agent fully absorbs water
Just can plant trees.Can also first apply water-retaining agent, after water-retaining agent fully absorbs water after rainfall, during planting plants, use base manure again.
Water-retaining agent amount of application determines depending on nursery stock size, typically by water-retaining agent: planting soil is to be advisable at 1: 500.The most every strain of arbor
35g, shrub every strain 25g.
Adding the planting soil dug out in plant pit during tree planting, the weight of the planting soil of addition is approximately 300～500 times of water-retaining agent, uses ferrum
Spade or hoe stir, and these planting soils being mixed with water-retaining agent retain about 1/3 bottom hole, and 2/3 around hole, plantation
The planting soil about 10cm of rear overlying is unmixed water-retaining agent.Tread.
Water-retaining agent is soaked in water, and the fully time of water suction wants more than 1h (water-retaining agent expands volume and changes over figure such as Fig. 1),
And watering time clock the most in a measure, the absorbent time of water-retaining agent is the shortest, and water absorption is the least, and water-retaining agent is wrapped in soil
In earth, being far below, with the contact area of water, the area being immersed in water, water-taking efficiency is limited further, it is difficult to give full play to
The effect that water conservation supplies water.
After water-retaining agent absorbs water in the rain, volume can fully be expanded, by volumetric expansion about 500 times after the saturated water suction of Fig. 1 water-retaining agent,
