Embodiment 1

[0028] The embodiment of the present invention provides a kind of method that is used for controlling the sand dune planting plant of sandy land, and it comprises the steps:

[0029] Reeds cut to 50-60cm are planted and sand barriers are set up in a ditch with a depth of 28-32cm. The number of layers of sand barriers is 2 layers, and the size of the sand barriers is 2m×2m=4m. 2 square. Apply basal fertilizer to the area to be sown. The basal fertilizer applied is diamine hydrogen phosphate and urea with a mass ratio of 2.8:1, and the application rate per mu is 13kg. Irrigation devices were installed in the sowing area, and the number of micro-spray belts of the irrigation device was set at 10 per 16 mu, and other settings were carried out as described in S3.

[0030] After the above measures are completed, planting will be carried out from early June to mid-August. The sowing rate is 4kg per mu, the sowing depth is 3-4cm, and the row spacing is 55cm. , the mass ratio of Cara...

Embodiment 2

[0032] The embodiment of the present invention provides a kind of method that is used for controlling the sand dune planting plant of sandy land, and it comprises the steps:

[0033] Reeds cut to 50-60cm are planted and sand barriers are set up in a ditch with a depth of 28-32cm. The number of layers of sand barriers is 3 layers, and the size of the sand barriers is 2m×2m=4m. 2 square. Apply base fertilizer to the area to be sown. The applied base fertilizer is diamine hydrogen phosphate and urea with a mass ratio of 3.2:1, and the application rate per mu is 15kg. Irrigation devices were installed in the sowing area, and the number of micro-spray belts of the irrigation device was 14 per 16 mu, and other settings were carried out as described in S3.

[0034] After the above measures are completed, planting will be carried out from early June to mid-August. The sowing rate is 6kg per mu, the sowing depth is 3-4cm, and the row spacing is 65cm. , The mass ratio of Caragana bar ...

Embodiment 3

[0036] The embodiment of the present invention provides a kind of method that is used for controlling the sand dune planting plant of sandy land, and it comprises the steps:

[0037] Reeds cut to 50-60cm are planted and sand barriers are set up in a ditch with a depth of 28-32cm. The number of layers of sand barriers is 2 layers, and the size of the sand barriers is 2m×2m=4m. 2 square. Apply basal fertilizer to the area to be sown. The basal fertilizer applied is diamine hydrogen phosphate and urea with a mass ratio of 3:1, and the application rate per mu is 14kg. Irrigation devices were installed in the sowing area, and the number of micro-spray belts of the irrigation device was 12 per 16 mu, and other settings were carried out as described in S3.

[0038] After the above measures are completed, planting will be carried out from early June to mid-August. The sowing rate is 5kg per mu, the sowing depth is 3-4cm, and the row spacing is 57cm. , the mass ratio of Caragana and ...

Abstract

The invention relates to the technical field of sandy land treatment and provides a method for sowing plant seeds in sand dunes to treat sandy land. The method includes: setting sand barriers at windgaps; applying base fertilizer; evenly mixing various seeds, and sowing 4-6kg of seeds into each mu of the sandy land, wherein the sown seed combination is optional one of the combination of Caraganamicrophylla, barley, Caragana korshinskii Kom. and wheatgrass, the combination of Hedysarum laeve Maxim, Artemisia desertorum, Caragana microphylla and wheatgrass, the combination of Artemisia halodendron, Achnatherum splendens, Medicago varia Martin. cv. Caoyuan No.3, Caragana microphylla, Calamagrostis epigejos, Artemisia frigida, Leymus secalinus, Leymus chinensis, Astragalus melilotoides Pall,Allium chrysanthum, Medicago sativa L. cv. Longmu 806, wild soybean, radix sileris, Elytrigia repens and Mengnong wheatgrass, and the like. By the method, plant coverage rate can reach 75-95% after the seeds sown into to the sand dunes grow into plants. The invention further provides a sandy land treatment method which comprises the method for sowing the plant seeds in the sand dunes to treat thesandy land and is capable of effectively treating the sandy land.

Description

technical field [0001] The invention relates to the technical field of sand control, in particular to a method for sowing plants in sand dunes for control of sand and a sand control method. Background technique [0002] At present, some areas in the north are seriously desertified. Taking the Hulun Lake Basin as an example, the Hulun Lake Basin has 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 in the Hulun Lake Basin degraded 20,300 km 2 , accounting for 60.73% of the grassland area in the lake area, and 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 w...
