Abstract

The invention provides a slope pressing belt greening method. The slope pressing belt greening method comprises steps: dividing into parallel belts, slotting, filling pore permeable water, preparing nutrient soil, greening a pressing belt, and backfilling soil. The slope pressing belt greening method relieves collapse and water and soil loss caused by soil mass self-gravity, reduces greening treatment task difficulty, improves greening soil loosening degree, and increases effectively greening area.

Description

Domatic pressure zone greening method

Technical field

The invention belongs to enviromental protection and improvement technical field, be specifically related to a kind of domatic pressure zone greening method.

Background technology

It is one technical barrier of capturing dry area in north china Difficult site greening that the exposed slope greening of loess is administered, China is dispersed with the loess bare slope of the length and breadth of land, is the natural hidden danger causing water and soil loss, airborne dust haze weather and threaten industrial and agricultural production, people's productive life safety.

This types of topography; according to incompletely statistics, only this city region just has more than 100,000 mu, loess bare slope because of formed and historical reasons be incoherent shape; be difficult to the green outstanding problem of tree planting cloth and do not have good vegetation protection, water and soil loss, phenomenon of soil erosion are quite serious.Current improvement only rests on takes engineering measure to railway, the high-risk location of keypoint road, cement, stone material etc. is utilized to build bank protection, prevent the generation of the geological disasters such as landslide, water and soil loss, domatic after the improvement object reaching part or local " imperial calamity harm reduction ", fundamentally thoroughly do not contain the generation of water and soil loss phenomenon and play the earth and drape over one's shoulders green ecological management effect, major part loess steep slope is still in naked state, have no aesthetic feeling can say, and with high costs, administer area extremely limited, become a blank spot of afforestation.

Summary of the invention

In order to solve the technical problem of above-mentioned Methods in Slop Improvement, the invention provides a kind of domatic pressure zone greening method.

The invention provides a kind of domatic pressure zone greening method, comprising:

By domatic by the height of vertical direction 1m parallel be divided into parallel band, by long 1m, groove height 10-15cm perpendicular to domatic downward-sloping 30 °, dark 20cm fluting, the earth pillar of 20-30cm is stayed in every meter of centre, in case whole groove collapses;

Upper and lower parallel band staggers into triangle disposition arrangement, and the basic Cheng Ping of each groove flies swallow shape, and two ends are 3-5 degree between senior middle school slightly;

Before pressure seedling, water and ooze band water 2 times, at every turn with till filling;

Two ends are inserted and water irrigation pipe, described in water irrigation pipe for long 20-25cm, two ends relative direction cuts the PVC round tube of the diameter 2.5cm at oblique angle at 45 °;

First at the Nutrition Soil of bottom land backfill 3-5cm, then nursery stock is arranged in order by strain spacing 10cm, buries to two ends and water irrigation pipe, bury seedling the longest main root 2-3cm place of watering inside irrigation pipe apex distance top of the inside;

Backfill Nutrition Soil is to trough rim, and make the oblique angle watering irrigation pipe expose, groove edge evenly sprinkles facet syndrom and covers Nutrition Soil simultaneously;

Water: after nursery stock of having planted in 40-60 days, every 7-10 days in good time, water irrigation pipe upper port by small hose aligning and water once, when watering, preferably add urea, to increase nutrient supply by 1% weight ratio; Water at every turn and should guarantee that infiltration can not be washed away domatic causing again; 12-14 point, when temperature is higher than more than 30 °, should sprays to nursery stock complete stool with sprayer in time, avoid day to burn noon every day.

Preferably, described nursery stock specification is more than leading thread 0.5cm, more than height of seedling 50cm, is more than or equal to the side radical of 5cm more than 15, and whole strain mechanical, root system damage, without damage by disease and insect, and the raw nursery stock of 1-2 of robust growth.

Preferably, described in water irrigation pipe for long 20-25cm, two ends relative direction cuts the PVC round tube of the diameter 2.5cm at oblique angle at 45 °.

Compared to prior art, domatic pressure zone greening method provided by the invention, the method alleviates landslide because the soil body causes from gravity, water and soil loss, reduces Afforestation task difficulty, improves green soil porousness, increase effective green coverage.

Accompanying drawing explanation

In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:

Fig. 1 is the pressure zone greenbelt structure chart of domatic pressure zone greening method provided by the invention;

Fig. 2 is the profile of the greenbelt of pressure zone shown in Fig. 1.

Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.

Two ends are inserted and waters irrigation pipe;

Pour water, after nursery stock of having planted, spring is every 7-10 days in good time, watering irrigation pipe with sprayer or small hose aligning waters once, when watering, preferably by 1% proportions urea, post to increase nutrient benefit, water at every turn and on a small quantity repeatedly, not only should guarantee infiltration but also can not wash away domatic causing; Preferably naturally osmotic as spotting, had both played high temperature cooling effect, can reach quickness and high efficiency again, necessarily can not lack of water in 40-60 days after particularly planting spring, and new root forms gentle seedling and supports one's family the phase just during this period of time, waters particularly crucial;

Anti-day burns, and at 12-14 point at noon every day, when air themperature is higher than more than 30 °, should sprays in time, avoid day burn and dry with sprayer to nursery stock complete stool.

Described nursery stock specification is more than leading thread 0.5cm, more than height of seedling 50cm, is more than or equal to the side radical of 5cm more than 15, and whole strain mechanical, root system damage, without damage by disease and insect, and the raw nursery stock of 1-2 of robust growth.

Please refer to Fig. 1 and Fig. 2, described pressure zone greenbelt 1 is opened in domatic downward-sloping 30 °, described in water the two ends that irrigation pipe 2 is inserted in described pressure zone greenbelt 1, described nursery stock 3 is sequentially arranged in described pressure zone greenbelt 1 by strain spacing 10cm.

The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
