Long-acting highland barley fertilizer and application thereof in efficient highland barley planting

The invention relates to a long-acting highland barley fertilizer and application thereof in highland barley planting, the long-acting highland barley fertilizer contains 100-300 parts of urea, 100-300 parts of diammonium phosphate and 400-1000 parts of bio-organic fertilizer, the bio-organic fertilizer contains more than or equal to 6 billion/g of effective viable bacteria, more than or equal to 70% of organic matters, more than or equal to 30% of mineral source humic acid and 6.5-8.0 of pH value, the effective viable bacteria are a combination of bacillus subtilis and bacillus licheniformis, and the effective viable bacteria are a combination of bacillus subtilis and bacillus licheniformis. The ratio of the bacillus subtilis to the bacillus licheniformis is 1: (1-4). According to the method, a fertilizer formula and a planting mode of the highland barley are scientifically screened, the long-acting highland barley fertilizer is applied as a base fertilizer at a time, the filling rate of the highland barley
