Method for planting oat grasses 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 grasses in a high latitude cold area. The method utilizes the mixing of different varieties, cooperates with suitable seeding, fertilizing conditions and the application in the high latitude cold area, can largely solve the problem of insufficient supply of high-quality pastures in the development of the grassland industry in a region, provides the high-quality pastures for the development of local grassland industry, and promotes the rapid and healthy development of the grassland industry.

Description

technical field [0001] The invention relates to the technical field of artificial grassland planting, in particular to a planting method of 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 308,100 tons in 2017. [0003] Oats are becoming more and more important as the main forage grass in alpine regions, and the...

AI Technical Summary

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 batch of oat grass, and the yield is low, less than 500 kg.

In a double-harvest technology we invented, it was found that the regeneration of the second crop was poor, which affected the output of the second harvest

Therefore, in improving the technology of one-time planting and two-harvesting, the regeneration and yield of oats directly affect the total hay yield and the income of the planters.

However, there is a lack of technology to solve the second-crop regeneration and increase production.
