Embodiment 1
[0019] Karamay west main canal Huangqiba deserted land, 10 mu of experimental land;
[0020] Seed collection and storage: In the middle and late September of 2013, the seeds were collected from vigorous plants in the growing area of Huangqiba Camelina, dried in the shade, and stored indoors under low-temperature and dry conditions;
[0021] Site selection and site preparation: Select a desert grassland with an annual precipitation of 100-300mm and a slope of 2-10‰, and build ridges at intervals of 2m along the contour along the main wind direction in winter and spring, with a height of 20cm to ensure the front of the ridge Enough to store winter and spring snowmelt water;
[0022] Sowing: Before the snow melted in the first ten days of April, 2014, the seeds of camel's hair quinoa by weight: grass carbon soil=1:10 were mixed evenly, and seeds were sown along the slope of 20 cm before the ridge;
[0023] Seedling stage management: After the permafrost on the surface disappea...

[0026] Fukang Beishawo sand wasteland, 10 acres of experimental land;
[0027] Seed collection and storage: In the middle and late September of 2014, the seeds were collected from the growing plants of Camelina chinensis in the desert steppe area of Fukang. After drying in the shade, they were stored indoors under low-temperature and dry conditions;
[0028] Site selection and site preparation: Select a desert grassland with an annual precipitation of 100-300mm and a slope of 2-10‰, and build ridges at intervals of 5m along the contour along the main wind direction in winter and spring, with a height of 30cm to ensure the front of the ridge Enough to store winter and spring snowmelt water;
[0029] Sowing: Before the snow melts in the first ten days of April, 2015, mix the seeds of camel's hair quinoa by weight: grass carbon soil=1:10, and sow seeds along the slope of 20 cm in front of the ridge;
[0030] Seedling stage management: After the permafrost on the surface disapp...

Abstract
The invention relates to a method for constructing and planting ceratoideslatens (J.F.Gmel.) revealet holmgren in desert grassland of an arid region. The method comprises the steps of seed collection and storage, land selection and preparation, sowing and management at the seedling stage. Water retaining ridges are arranged in sloping fields among mounds of the desert grassland, ceratoideslatens (J.F.Gmel.) revealet holmgren seeds are mixed with soddy soil, the mixture is stirred to be uniform, the seeds are scattered on the sloping field which is 20 cm in front of each ridge, and the method follows emergence rules of seedlings of ceratoideslatens (J.F.Gmel.) revealet holmgren to create the appropriate soil environment for germination of the ceratoideslatens (J.F.Gmel.) revealet holmgren seeds and growth of the seedlings, so that artificial construction and plantation of the seedlings are achieved. By means of the method, the defects that germination of the ceratoideslatens (J.F.Gmel.) revealet holmgren seeds and growth of the seedlings are inhibited by drought and water shortage, and transplantation of the ceratoideslatens (J.F.Gmel.) revealet holmgren seedlings is complex are overcome, on-site construction and plantation of ceratoideslatens (J.F.Gmel.) revealet holmgren are achieved, and furthermore, technical reserve is accumulated for fostering improvement of the desert grassland of the arid region.
Description
technical field [0001] The invention relates to a plant cultivation technique, in particular to a method for planting camel's wool on a desert grassland in an arid region. Background technique [0002] Xinjiang has a vast natural grassland area and abundant resources. The total grassland area is 860 million mu, and the usable area is 720 million mu, ranking third in the country. Due to overgrazing, human destruction, etc., 85% of the natural grasslands are currently degraded to varying degrees, of which 40% are severely degraded, and the grass production is only 30% to 50% of that in the 1960s and 1970s . Protecting and making good use of grassland resources is related to the sustainable development of animal husbandry in Xinjiang. At present, the area of natural grassland in Xinjiang accounts for more than 99% of the total pasture land, and the proportion of artificial grassland and improved grassland is less than 1%. [0003] Camelina is a xerophytic semi-shrub of the...
