High-quality highland barley seed production method

The invention belongs to the technical field of crop seed production, and particularly relates to a high-quality highland barley seed production method which comprises the following steps: selecting a field parcel in which preceding crops are not highland barley as a highland barley seed breeding field; nitrogen fertilizer accounting for 60% of the total nitrogen consumption and all phosphorus-potassium fertilizer are applied in the seedling stage; the nitrogen fertilizer with the total nitrogen use amount of 25% is topdressed in the jointing stage, and the nitrogen fertilizer with the total nitrogen use amount of 15% is topdressed in the booting stage; artificially identifying atypical abnormal plants in the seedling stage, the jointing stage and the mature stage, thoroughly pulling out the abnormal plants with roots when the abnormal plants are found, and taking the abnormal plants out of the field to be discarded; after the highland barley is completely ripe, a combine harvester is adopted for harvesting a
