Embodiment 2

[0037] This embodiment also provides a method for controlling sandy land in Hulun Lake, comprising the following steps:

[0038] Planting is carried out between mid-June and early August. First, prepare matrine medicament, and each kilogram of matrine corresponds to 330 kg of water to make the corresponding medicament. Then, 6 days before sowing, spray chemicals on the sandy land, and use 0.55 kg of chemicals per mu of sandy land.

[0039] Test the pH of the sand to ensure that the pH of the area to be planted is between 7.5-8.2.

[0040] Three layers of non-biological sand barriers will be planted on the sand. The non-biological sand barriers are formed by grass grids, and the planting depth of each layer of grass grids is 40 cm. The size of each grass grid is 1m×1m=2㎡ .

[0041] Caragana microphylla seeds are mixed with urea and diamine, the consumption of urea is 14 kg per mu of sandy land, and the consumption of diamine is 12 kg per mu of sandy land.

[0042] Then the s...

Embodiment 3

[0045] This embodiment also provides a method for controlling sandy land in Hulun Lake, comprising the following steps:

[0046] Planting is carried out between mid-June and early August. First, prepare matrine medicaments, and each kilogram of matrine corresponds to 300 kg of water to prepare the corresponding medicament. Then, 7 days before sowing, spray chemicals on the sandy land, and use 0.50 kg of chemicals per mu of sandy land.

[0047] Test the pH of the sand to ensure that the pH of the area to be planted is between 7.7-8.1.

[0048] Three layers of non-biological sand barriers will be planted on the sand. The non-biological sand barriers are formed by grass grids, and the planting depth of each layer of grass grids is 35 cm. The size of each grass grid is 1m×1m=2㎡ .

[0049] Caragana microphylla seeds are mixed with urea and diamine, the consumption of urea is 13.5 kg per mu of sandy land, and the consumption of diamine is 11 kg per mu of sandy land.

Abstract

The invention relates to the field of sand land treatment, specifically to a treatment method for a sand land in the Hulun Lake. The treatment method for the sand land in the Hulun Lake comprises thefollowing steps: arranging at least two layers of non-biological sand barriers on the sand land, planting seedlings of Achnatherum splendens, Leymus and Artemisia halodendron in the sand land where the innermost layer of the non-biological sand barriers surrounds, and planting Caragana microphylla seeds among non-biological sand barriers. According to the invention, through combination of biological sand barriers formed by planting of the Caragana microphylla with the non-biological sand barriers, wind-blown sand can be effectively prevented, and quicksand is fixed; meanwhile, through plantingof the Achnatherum splendens, the Leymus and the Artemisia halodendron in sand barriers, sandification can be further inhibited, and grassland degradation is prevented.

Description

technical field [0001] The invention relates to the field of sand land control, in particular to a method for sand land control of Hulun Lake. Background technique [0002] Hulun Lake Basin is 33,300 km 2 grassland, accounting for 80.13% of its total area. The grassland ecosystem has important ecological functions such as water and soil conservation, windbreak and sand fixation, and maintenance of biodiversity. At the same time, it provides grassland resources for animal husbandry. According to the analysis of remote sensing images in 2013, the grassland degradation in the Hulun Lake Basin was 20,300 km2, accounting for 20,300 km2 of grassland area in the lake area. 60.73% of the desertified grassland area is 15.53 million mu. The Hulun Lake Basin, coupled with continuous drought and overgrazing along the lake, has shrunk the wetland area and continued to reduce biodiversity. To protect the resources of the Hulun Lake Basin, the national and local governments have investe...
