Embodiment

[0069] Embodiment: the artificial propagation of wild Elymus bachinii seed in Tibet

[0070] The wild Elymus bachinii mature stage harvested in Baqing County (4300m above sea level) in the Tibet Autonomous Region in that year, at this time, the seed color is white-yellow, partly purple, and the water content is 32% to 43%. Store at room temperature (20°C-35°C) for 3 months, and keep it at 5-10°C for 7 days during the storage period. In the spring of the second year, sow on the flat, open and medium-fertile Lhasa River in Qushui County, Lhasa (3600m above sea level), with a pH of 6.9 to 7.2; before sowing, the seeds are sprayed with 0.02 to 0.1% potassium nitrate (KNO 3 ) solution for wet treatment; adopt a row spacing of 45cm, the sowing depth is 1cm-2cm, and the sowing rate is 20-28 kg per hectare. Apply base fertilizer per hectare (containing 160-230 kg of pure nitrogen and 110-165 kg of phosphorus pentoxide), and apply it once before sowing. In the year of sowing, the se...

Abstract

The present invention discloses an artificial method for breeding seeds of the Tibetan wild Baqing lyme grass; with the method, people collect the seeds of the wild Baqing lyme grass and break the dormancy of seeds; people choose the sowing soil for fertilizing, irrigation, spraying plant growing regulator and implement artificial auxiliary pollination until the field management after the seeds are harvested; the method solves the existent problem of artificial breeding of wild Baqing lyme grass seeds; with the method, the production and quality of the seeds of Baqing lyme grass can be promoted and the Baqing lyme grass can be further utilized in the plant restoration in degenerated pasture, ecological construction and pasture stockbreeding production on the Qinghai and Tibet plateau.

Description

technical field [0001] The invention belongs to the field of agriculture and animal husbandry, and relates to a method for artificially breeding seeds, in particular to a method for artificially breeding seeds of wild Elymus bachinii in Tibet. technical background [0002] Elymus nutans Griseb (Elymus nutans Griseb) is a perennial sparse-clump grass of the grass family Elymus nutans, native to Baqing County, Tibet; it is widely distributed in the Qinghai-Tibet Plateau at an altitude of 2500m to 4700m, and the roots of the growing plants are well developed. The fibrous roots can reach 40cm to 90cm in the soil, which is a good soil and water conservation plant. The stems are erect, with a plant height of 80cm to 100cm. It is a kind of forage grass with strong adaptability in the typical cold temperature-subarctic zone type, especially with strong low temperature growth characteristics, strong cold resistance, and can normally survive the winter under severe cold conditions be...
