How does Sanhua plum adapt to the climate?

Choose loam and sandy loam; Thickness of soil layer ≥ 60 cm; The pH value is 6-6.5; Organic matter content ≥ 2.0%; Sanhua plum is a shallow-rooted fruit tree, its root spread can be (0.6- 1) times larger than that of the crown branches, its root depth is only 1/5- 1/3 of the height of the tree, its absorption root is generally within 45cm, and10-30cm is a vigorous growth area, so it is.

Fertilization: apply decomposed organic fertilizer ≥15t, bean cake fertilizer ≥ 2.5t and nitrogen fertilizer ≤ 0.15t per hectare every year; Fertilization requires the combination of base fertilizer and topdressing. The base fertilizer is mainly decomposed farmyard manure, and 25-50 kg of decomposed farmyard manure is applied to each mature Sanhua plum.

Topdressing compound fertilizer 1 time before flowering, topdressing 1 time after physiological fruit drop, spraying 0.2% boric acid aqueous solution in case of boron deficiency in early flowering, spraying 0.4% potassium dihydrogen phosphate 1-2 times from late May to early September, and spraying 0.2%-0.3% calcium nitrate/kloc-0 during fruit expansion.
