Abstract

The method for spreading the lawn on the surface of desertified earth and rock includes such steps as choosing sedge and nutgrass flatsedge as seeds, sowing on the nutgrass earth or marshland earth to obtain lawn units, transplanting them by arranging them ordely and fixing them by wire when the slope greater than 20 degrees, and irrigation.

Description

Utilize the lawn laying method of sedge greening desertification rock open ground

Affiliated field

The invention belongs to a kind of forestry greening technique, specifically specially artificial greening is the lawn laying method at desertification rock exposed ground.

Background technology

Laying the lawn is one of basic skills to the ground greening, generally realize easily for the thicker soil place, but open ground is just very difficult for the very thin desertification ground, particularly rock of soil layer, as highway slope protection, its soil horizon is very thin, or even do not have soil horizon above it by the rock bank protection, and majority is some sandstone faces, the root system of plant on general lawn can't penetrate underground, its survival rate is extremely low, and the ability of particularly surviving the winter is poorer.

Technical scheme

The objective of the invention is manually to lay the lawn method at the rock exposed ground of desertification.The Xiu Shi sedge of sedge family, tower head sedge grow prolifically.Owing to tiller on the ground, avoided the influence of poor soil; Again since its with mycosymbiosis be the growth of clump shape, in the run-up of soil top organic matter, especially tillering node place organic matter is maximum.Perennation like this, thick grass base portion projection is the hillock shape as a result, forms tongue block of wood, and precipitation is stagnated between tower head.Stop flowing of water, form fixedly perennial artificial lawn of rock exposed ground gradually, the ability of surviving the winter extra-heavy.The inventive method comprises:

1. careless base is made

Select sedge family five flowers and plants pastures and Xiu Shi sedge or tower head sedge as grass seeds, artificial planting in meadow soil or meadow-boggy soil.

After more than the high 10cm of above-mentioned careless base, separating area is 0.05-0.02 square metre, and soil thickness is the careless base unit of 10-20cm.

2. lay

Grass is after base is transplanted to the scene, and proper alignment is afforested ground at need, when in the gradient during greater than 20 ° steep location operation, uses iron wire and intersects in length and breadth mutually and fixes each careless base.

After finishing, transplanting careless base is watered in good time

Meadow soil of the present invention should be rich in a large amount of organic matters, answers softness to be rich in potassium, calcium and a large amount of humus, and soil is granular structure, its soil profile A ₀Layer (the 0-2cm degree of depth) is the draft The litter.A ₁(the 2-20cm degree of depth) is that black humidity, light earth, granule, root system are intensive tight slightly.Earth during the black palm fibre of B layer (the 20-38cm degree of depth) is wet, granular texture, root system of plant is medium, and fine sand is strip and distributes.More than C layer 38cm is thick is fourth of the twelve Earthly Branches stone.

Described meadow-boggy soil

Meadow-boggy soil

The soil richness is organic, organic water absorption height, and gas capacity is few in the soil, and soil air and atmosphere exchange are difficult, form anaerobic condition, growths such as the Xiu Shi sedge of suitable thicket plant such as sedge family, tower head sedge.

Its soil profile is:

The Ag layer, the 12-29cm degree of depth, black palm fibre, middle earth, unsettled crumbled structure, tighter, wet, there is the incobation spot part, and Root Distribution is medium.

The Bg layer, the 29-57cm degree of depth, sepia, light sticking, many gray corrosions, heavily wet, tight, root system is few.

The C layer, the following degree of depth of 57cm is the finger stone matrix.

For conscientiously carrying out " Tian Bao engineering ", effectively suppress the reverse in forest land, strengthen cause the exposed management of forest land rock because of engineering construction.The present invention adopts careless base to transplant the recovery forest cover.Now adding the rock open ground that causes repairing the roads on east exit road, district at 111 national highways transplants successfully.

Claims

1. lawn laying method that utilizes sedge greening desertification rock open ground

Comprise:

The grass base is made

Select sedge family five flowers and plants pastures and Xiu Shi sedge or tower head sedge as grass seeds, artificial planting in meadow soil or meadow-boggy soil;
