Embodiment 1

[0060] A kind of double-harvesting planting method of embodiment 1

[0061] 1. Selection of oat seeds

[0062] The used oat seeds are naked oats and hulled oats suitable for planting in alpine regions.

[0063] The oat seeds used are all commercial oat seeds harvested in 2016, purchased from major domestic forage seed companies. The main varieties include Qinghai 444, Qingyin 2, Qingyin 3, and Jiayan 2 four commercial oat seeds.

[0064] 2. Seed treatment

[0065] Before sowing, put the selected seeds in a ventilated and sunny place for 2-3 days to promote enzyme activity, increase the air permeability and water permeability of the seeds, kill the germs on the surface of the seeds, and increase the germination rate and germination potential of the seeds . The oat seeds that have been coated do not need to be treated with chemicals, and the uncoated ones are treated with seed dressing. The seed dressing agents are conventional insect-resistant agents such as imidacloprid, t...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of artificial grassland planting, in particular to a method for planting oat grass in high-latitude cold regions. Background technique [0002] Oats, belonging to the genus Avena L. in the family Poaceae in plant classification, are annual grain and feed crops. The most widely used in production are naked oats (A.nuda L.) and leather oats (A.sativa L.). my country's oats are mainly planted in spring and summer in the north and autumn in the south, specifically in North China, Northwest Southwest and Northeast China. High-quality oat grass plays an increasingly important role in the development of my country's animal husbandry, especially in areas lacking high-quality forage in alpine regions. According to statistics, the import volume of oat grass increased from 1,500 tons in 2008 to 151,500 tons in 2015, and 108,700 tons in the first half of 2016, a year-on-year increase of 46%. Oats are becoming more an...
