A kind of planting method of oat grass in high latitude cold area

Abstract

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. The planting method includes: selection of oat seeds, seed treatment, site selection, site preparation and fertilization, sowing, field management, harvesting of the first crop of oat grass, harvesting of the second crop of oat grass; fertilization is: nitrogen 2.8-3.2kg / mu, phosphorus 1.8 ~2.2kg / mu, potassium 0.9~1.1kg / mu; to harvest the second crop of oat grass: spray the mixture of cytokinin and brassinosteroid on the oat stubble field, apply 9~11kg / mu of diammonium phosphate, The second crop of oat grass was harvested from the grain filling stage to the milk ripening stage. The technology mainly includes sowing in early spring to increase the amount of phosphorus fertilizer and the ratio of nitrogen and potassium, harvesting the first stubble grass at the filling stage, spraying a certain concentration of brassinosteroid and cytokinin mixture, and topdressing diammonium phosphate at the same time to promote Tillering and growth, increase tiller density per unit area, and promote high yield of oat grass.

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

The high-latitude cold region is an important base for the development of animal husbandry in my country. The gap for high-quality forage grass in the high-latitude cold region is very large. Many high-quality forage grasses need to be transported thousands of miles away, which increases the cost of forage grass and restricts the development of local animal husbandry.
