Method for clone plant sand stabilization

A sand-fixing method and plant technology, applied in botany equipment and methods, plant cultivation, horticulture, etc., can solve the problems that the survival rate of cutting branches is not easy to survive, easy to die, and increase the friction and wind force of the desert surface, so as to improve the vegetation coverage , Reduce survival pressure and increase survival rate

Problems solved by technology

There are also certain defects in the above method. The use of shrub cuttings to plant grid-like plant belts can play a certain role in increasing the friction of the desert surface and reducing wind power. However, direct cutting of shrub branches on desert land leads to cutting The survival rate of the branches is not easy to survive, it is easy to die, and it needs to be artificially filled many times before it is possible to form a grid-like plant belt

Embodiment 1

[0044] Composting of mixed cattle and sheep manure: The cattle and sheep manure is mixed according to the mass ratio of 1:2. 14 days before fertilization, the semi-pit composting system is adopted, and the top is wrapped with two layers of agricultural film to keep warm. The total amount of cattle and sheep manure per day hm 2 Use 10.2t.

[0045] Planting of grid-shaped plant belts: The planting site is in Songpan County, Sichuan Province. The land vegetation coverage rate is 17%, which is lower than 25%. It is a heavily desertified land. The planting time is on April 17, after the rain.

[0046] Place materials needed for construction near the construction site, such as figure 1 As shown in the figure, set the transect line according to the specifications of 2m×2m on the sandy land, make a transect line according to the longitude and latitude respectively, and work downwards in sequence to ensure orderly specification and compliance with the specifications.

Embodiment 2

[0053] Composting of mixed cattle and sheep manure: Mix cattle and sheep manure according to the ratio of 1:2. 14 days before fertilization, the semi-pit composting method is adopted, and the top is wrapped with two layers of agricultural film to keep warm. The amount of cattle and sheep manure is 8.7t / hm 2 .

[0054] Planting of grid-shaped plant belts: on May 9, cloudy to sunny, in Ruoergai County, Sichuan. The land vegetation coverage rate is 27%, higher than 25%, which is moderately desertified land.

[0055] Place materials needed for construction near the construction site, such as figure 1 As shown, set the sample line on the sandy land according to the specification of 1.5m×1.5m, make a sample line according to the longitude and latitude respectively, and work downwards in turn to ensure orderliness and compliance with the specifications.

[0056] Select seedlings with soil balls of two annual shrubs, seabuckthorn and alpine willow, and dig out a planting hole in eac...

Abstract

The invention relates to a method for clone plant sand stabilization, and belongs to the technical field of land desertification treatment. The method for clone plant sand stabilization comprises thesteps that a latticed plant belt is planted by using shrubs and intensive clone plants, and then the guerilla clone plants and the intensive clone plants are planted in grids in a mixed mode. According to the method, the shifting sand stabilization fixing effect is greatly improved, the recovery rate of land vegetation is greatly increased, and the coverage rate of the land vegetation can be restored to 80% or above within 1-2 years; the biological yield per unit area can be greatly increased within 1-2 years by 50-250 times, and the species richness and the species number in a treatment region are also greatly improved; in general, the treatment capacity on desertificated land and the shifting sand stabilization capacity of the sand stabilization method are better than those of other methods.

Description

technical field [0001] The invention relates to a sand-fixing method for cloned plants, which belongs to the technical field of land desertification control. Background technique [0002] For a long time, due to the serious interference of global climate change and human activities such as over-deforestation and over-grazing of grasslands, forest and grass vegetation have been severely damaged around the world, land has been degraded and desertified, and soil erosion has intensified. Until the beginning of the 21st century, globally in 2011, more than 12 million hectares of arable land could not be cultivated due to land desertification every year. According to data, more than 110 countries around the world have experienced or are likely to experience desertification of cultivated land. In Africa, more than 1 billion hectares of land have been affected by desertification; in Asia, about 1.4 billion hectares; in North America, the proportion of desertified land to wasteland ...
