PendingCN110612827ANot easy to infestationDwarfing effect is obviousGraftingCultivating equipmentsMalus robustaBud
The invention discloses a g rafting cultivation method suitable for apple dwarf interstock seedlings in Alpine land. A malus robusta seedling sowed in the first year is selected as a base stock, an SH-line dwarf stock seedling grafted on the base stock is selected as a dwarf interstock seedling, each seedling needs to be full in bud tip, high in lignification degree and with diameter thickness being 0.5-1.2cm, and grafting survival rate is high. A T-shaped bud grafting method is adopted for grafting, and then conventional management like stock cutting, sprout removal, weeding and soil loosening, fertilizing and pest and disease prevention and control is performed on grafted seedlings. Dwarf interstock apple seedlings after successful grafting have obvious dwarf effect. The SH-line dwarf stock is used as an interstock, is highly cold-resistant and can resist low temperature of minus 36 DEG C, thereby being suitable for high-cold high-altitude regions; the dwarf interstock apple seedlings are high in flexibility, windproof, uvioresistant, extremely high in affinity and unobvious in big-small feet phenomena of the base stock and variety seedlings after grafting; fruiting period is advanced, the seedlings can bear fruit in the third year, fruit coloring rate is increased by 25%, and commodity rate is increased by 25%; orchard establishment cost is low.
