(2) Site conditions.
The altitude is 500- 1500m, the soil type is loam or sandy loam, the organic matter content is 1.2%-3%, the pH value is 7.0-7.5, and the groundwater level is 2m below the surface.
(3) Cultivation techniques.
1. Breeding: Take local walnut as rootstock and parent tree scion for grafting.
2. Planting: the planting time is 65438+1mid-October, and the planting density is ≤490 plants/hectare.
3. Shaping and pruning: adopt natural open heart-shaped or evacuation layered shape for fixed pruning to ensure ventilation and light transmission.
