The measures to promote the abundance of the following aspects: 1 appropriate density is the appropriate density of apricot fast-growing yield an important factor, too dense forest wood canopy closed early, poor ventilation and ventilation, flower degeneration, fruit set rate is low; Small area factor, low coverage, inadequate use of land and space, resulting in a waste of light energy. Generally use 4m × 6m or 6m × 6m is appropriate. 2 planting spring in March, mid-planting. Pit specifications: 1m × 1m × 1m. Per hole rotting manure 25 ~ 35
