Abstract

The utility model relates to a special film for planting trees. The irrigation of the existing plant commonly uses sprinkling irrigation and trickle irrigation. When the methods are used for irrigating, not only the construction cost is especially high, but also the maintenance cost is large. The roads and the mountain areas with no large economic expenditure conditions can not irrigate by the existing ability, particularly the northwest areas with comparative dryness. The utility model comprises a polymer thin film. The middle of the thin film is provided with a hole 1 of 10 cm-20 cm. An opening 2 is arranged from the hole 1 to the edge of the thin film. Granular long-effective solid water is arranged under the thin film. The utility model is used for water holding and water storage for trees in positions with inconvenient artificial irrigation carrying for whole year. The utility model can be used for repetitively irrigating.

Description

The special-purpose film of planting trees

The utility model relates to the special-purpose film of a kind of woody plant transplanting or water and soil conservation.

Existing plant is irrigated except that natural rainfall, general sprinkling irrigation, the drip irrigation of adopting, these methods irrigate that not only construction cost is high especially, and also big surprising of maintenance cost, for the highway that does not have huge economic expenditure condition, mountain area, the particularly the Northwest of arid relatively, still be not existing ability can accomplish.

The purpose of this utility model is to provide a kind of tree planting special-purpose film, can keep, collect natural precipitation, along the supply time of long water, for the irrigation of tree planting and trees is offered help.

The purpose of this utility model is achieved in that

The special-purpose film of planting trees, its composition comprises: macromolecule membrane, the centre of described film has the hole of 10-20Cm, and there is opening at described hole to the edge of described film.

The special-purpose film of above-mentioned tree planting, the profile of described film is circle or polygon.

The special-purpose film of above-mentioned tree planting, described film is platform shape side.

Dispose granular long-acting solid water below the special-purpose film of above-mentioned tree planting, described film.

Advantage of the present utility model is:

1. because the middle opening that communicates with the edge that has, can easily this product be enclosed within on the trees, reduce the trees ' root evaporation of moisture content on every side, our experiments show that, evaporation discharge is 2000 millimeters area, use this product after, evaporation discharge is reduced to 250 millimeters, keep the moisture in the soil preferably, strengthened the ability of drought resisting.

2. make platform shape and can collect natural rainfall, its enrichment is also added in the soil and granular long-acting solid water of plant root in time, moisture is discharged slowly according to the trees needs, be utilized fully, improve the availability of water as funnel.

3. can check the trees growth of weeds on every side by covering, prevent the shunting of moisture.

4. after using this product can guarantee once fully to supply water, satisfy trimestral trees water supply needs, trees are tided over dry season smoothly, arrive rainy season, the back particularly plant trees spring as long as sufficient moisture was provided at that time, just can guarantee the water supply before arriving rainy season, improve the survival rate of trees.This product can be and so forth, the long-term use.

5. use this product to compare, can reduce 90% of construction cost and maintenance cost with traditional sprinkling irrigation or drip irrigation.

Accompanying drawing 1 is a structural representation of the present utility model.Accompanying drawing 2 is vertical views of accompanying drawing 1.

Accompanying drawing 3 is when cooperating long-acting solid water to use and the location diagram of trees.

Be further described below in conjunction with accompanying drawing:

Embodiment 1:

The special-purpose film of planting trees, its composition comprises: macromolecule membrane 4, the centre of described film porose 1, the size of the area in hole can doubly be provided with according to the 2-3 of the diameters of trees, the length in the narrow place in hole can be greater than 5Cm, general 10-20Cm, described hole 1 to the edge of described film has an opening 2 at least.

Embodiment 2:

Embodiment 3:

The special-purpose film of above-mentioned tree planting, described film is the side of truncated cone-shaped, described opening 2 places can be overlapped to make.

Embodiment 4:

Dispose granular long-acting solid water 3 below the special-purpose film of above-mentioned tree planting, described film.
