select loam and sandy loam; Thickness of soil layer ≥ 6 cm; The pH value is 6-6.5; Organic matter content ≥ 2.%; Sanhua plum is a shallow-rooted fruit tree, its root spread can be (.6-1) times greater than the crown branch spread, its root depth is only 1/5-1/3 of the height of the tree, its absorption roots are generally within 45cm, and 1-3 cm is a vigorous growth area, so its root system requires higher air content in the soil, and generally, the soil air content is ≥5%, and the root system begins to grow.

Fertilization: apply decomposed organic fertilizer ≥15 tons, bean cake fertilizer ≥2.5 tons and nitrogen fertilizer ≤.15 tons per hectare every year; Fertilization requires the combination of base fertilizer and topdressing. The base fertilizer is mainly decomposed farmyard manure. Each mature Sanhua plum is applied with 25-5 kg decomposed farmyard manure, and the topdressing is applied with compound fertilizer before flowering and after physiological fruit drop. In view of boron deficiency at the early flowering stage, .2% boric acid aqueous solution is sprayed, and .4% potassium dihydrogen phosphate is sprayed once or twice from late May to early September, and .2% is sprayed during fruit expansion.
