The invention relates to the technical field of artificial
grassland planting, in particular to a method for planting
arrhenatherum elatius (L.) presl in a cold region of a circumpolar
latitude. The planting method comprises the steps of
arrhenatherum elatius (L.) presl seed selection,
seed treatment, land selection and
land preparation, seeding, field management, first batch of
arrhenatherum elatius (L.) presl harvesting and second batch of arrhenatherum elatius (L.) presl harvesting, wherein the steps of seeding comprise that the seeding quantity is 14-15 kilograms per mu, the date of seeding is a period when the soil freezing reaches up to 10 centimeters, the depth of seeding is 5-6 centimeters, and the line spacing of
drill seeding is 14-16 centimeters; fertilization is carried out with 2.6-3.0 kilograms of
nitrogen per mu, 1.5-1.7 kilograms of
phosphorus per mu and 1.5-1.7 kilograms of
potassium per mu in seeding. According to the method for planting the arrhenatherum elatius (L.)presl in the cold region of the circumpolar
latitude, the characteristics are comprehensively considered that the interannual change of the weather is large in the cold region of the circumpolar
latitude, abnormal weather occurs suddenly and frequently, the cold endurance of the arrhenatherum elatius (L.) presl is strong, the tillering capacity and
sprouting capacity of root systems are strong, and the growth period is short, the effective accumulated temperature, annual sunshine time and the like in the cold region of the circumpolar latitude are fully used, and the yield per unit area of the arrhenatherum elatius (L.) presl is improved.
