Planting method for oat grass in high-latitude cold area

Abstract

The invention relates to the technical field of artificial grassland planting, in particular to a planting method for oat grass in a high-latitude cold area. The planting method includes the steps ofselection of oat seeds, seed treatment, land selection and preparation, sowing, field management, harvesting of first-stubble oat grass, multi-cropping and harvesting of multi-cropped oat grass; during sowing, the seeding amount is 14-15 kg / mu, the period when the soil is thawed for 10cm in depth is selected as the sowing period, the sowing depth is 5-6 cm, and the strip sowing spacing is 14-16 cm; during sowing, fertilization involves nitrogen 2.6-3.0 kg / mu, phosphorus 1.5-1.7 kg / mu and potassium 1.5-1.7kg / mu. According to the method, the characteristics are comprehensively considered that the interannual variation of climate in the high-latitude cold area is big, the temperature is low, oats are excellent in cold tolerance and short in growth period, and the low temperature after the autumn comes can still satisfy growth conditions of the oats; the effective accumulated temperature, the annual sunshine duration and the like of the high-latitude cold area are fully used, and the yieldof the oat grass per unit area is increased.

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...

Problems solved by technology

For the planting of oat grass in high-latitude cold regions, the most suitable sowing period is from mid-May to mid-to-late June. Conventional planting can only harvest one crop of oat grass, and the yield is low
