Embodiment 1

[0024] Example 1: Vegetation Restoration of Wasteland in Miyun Reservoir Area

[0025] In 2006, on the 300 mu of wasteland with vegetation coverage less than 20% in the Miyun Reservoir area of ​​Beijing, the following methods were used to restore the vegetation of the wasteland:

[0026] (1) Land consolidation: mow the original plants on the barren land, plow the soil 22cm deep with the tractor and five plows, remove the roots of woody plants and stones with a diameter greater than 20cm in the soil, break up the large soil clods in the soil, and level the land ;

[0027] (2) sowing: in mid-August, on the land after leveling, ditch and sow the awnless brome grass seed with a no-tillage machine, the depth of the ditch is 10cm, the germination rate of the grass seed is 90%, the purity 95%, and the seeding rate is 2kg / mu, according to the weather forecast, it is determined that the sowing time is 5 days before the moderate rainy day; after sowing, cover the soil with 2cm, and sup...

Embodiment 2

[0031] Example 2: Vegetation Restoration of Wasteland on Both Banks of Chaobai River

[0032] In 2008, on the 250 mu of wasteland with a vegetation coverage of less than 15% on both sides of the Chaobai River in Beijing, the following methods were used to restore the vegetation of the wasteland:

[0033] (1) Land consolidation: mow the original plants on the wasteland, plow the soil 20cm deep with the tractor and five plows, remove the root system of woody plants and stones with a diameter greater than 20cm in the soil, break up the large soil clods in the soil, and level the land ;

[0034](2) sowing: in the first ten days of July, on the land after leveling, ditch and sow the awnless brome grass seed with a no-tillage machine, the depth of the ditch is 12cm, the germination rate of the grass seed is 85%, the purity 92%, and the seeding rate is 2.5kg / mu; cover soil 1cm after sowing, and suppress with a compactor;

[0035] (3) Irrigation: After sowing, water is pumped and sp...

Embodiment 3

[0038] Example 3: Vegetation Restoration of Wasteland in Guanting Reservoir Area

[0039] In 2012, on the 1,000 mu of wasteland with vegetation coverage less than 10% in the Guanting Reservoir area of ​​Beijing, the following methods were used to restore the vegetation of the wasteland:

[0040] (1) Land consolidation: mow the original plants on the barren land, plow the soil 22cm deep with the tractor and five plows, remove the roots of woody plants and stones with a diameter greater than 20cm in the soil, break up the large soil clods in the soil, and level the land ;

[0041] (2) Sowing: In mid-June, use a ditch opener to carry out artificial ditching on the leveled land, with a ditch depth of 10 cm. According to the weather forecast, in the first 2 days of the light rain day, the bromegrass seed is artificially sown, and the grass The germination rate of the seeds is 90%, the purity is 97%, and the sowing rate is 3kg / acre; after sowing, cover the soil with 2cm, and use a ...

Abstract

The invention relates to a method for rapidly recovering vegetation of wasteland. The method uses deep ditching and shallow covering ways to sow awnless brome on the wasteland, and the awnless brome is managed and protected for 2-3 years to achieve vegetation recovery. The method has few actual operation steps, and is simple and feasible, low in cost, low in energy consumption, simple in process, and fast in effectiveness, and is convenient for practical application and popularization. After the technology is applied, vegetation coverage is high, and restoration effect is stable. Using the method to restore vegetation of the wasteland, the vegetation of the wasteland can be rapidly established in a short time, to form effective earth's surface cover degree. The method prevent soil nutrient from running off with water-wind erosion, increases soil, retains fertilizer and soil fertility, and reduces soil moisture evapotranspiration, increases water-holding capacity, and conserves water, so as to establish a friendly ecological environment in which wasteland vegetation covers effectively in a long time and ecosystem service function continuously develops.

Description

technical field [0001] The invention relates to the field of ecological environment management, in particular to a method for rapidly recovering vegetation on barren beaches. Background technique [0002] The barren beach area generally has a bad climate, barren and dry soil, and sparse vegetation, which can easily cause severe wind erosion and soil erosion on slopes, which will lead to accelerated soil nutrient loss, decreased water holding capacity, increased soil drought, and difficulty in maintaining the normal life cycle of plants. Vegetation has been severely degraded, and ecosystem service functions have been greatly weakened. The root cause of this phenomenon is the lack of effective vegetation coverage on the surface, the insufficient ability of the soil to resist wind erosion and water erosion, and the development of the ecological environment has entered a state of a vicious circle. At present, natural restoration methods such as grazing prohibition, enclosure or...
