When will the oak tree be planted?

Oak seeds can germinate without treatment when planted in spring, but the germination time is longer. If it is treated at 5 degrees Celsius for 30 to 45 days before sowing, the germination rate can be improved, and it can germinate in 2 to 3 weeks.

Sowing and seedling raising, selecting healthy mother trees (20-80 years old), timely collecting seeds and selecting pure varieties, carefully selecting fine varieties and selecting nursery land, deep ploughing, harrowing, grinding, furrowing and drilling, and carefully managing appropriate sowing amount and density for thinning and cutting roots.

The survival rate of softwood cutting is high, the survival rate of softwood cutting of Quercus variabilis is 56%, that of hardwood cutting is 10%, and that of Quercus acutissima is 60%-70%. Grafting experiments were carried out on scions collected from different tree species such as Quercus variabilis at different stages. The results showed that the grafting survival rate was high in spring germination stage.

Extended data:

Strong stress resistance, resistance to dryness, high temperature and humidity, frost and urban environmental pollution, strong wind resistance, like well-drained soil, but can also grow in cohesive soil.

Oak likes sandy loam or slightly acidic soil with good drainage, is resistant to environmental pollution and has strong adaptability to barren, arid, acidic or alkaline soil. Oak grows at a moderate speed, growing 60 cm high on wet and well-drained soil every year.

Portugal, China, Liaoning, Xiong Yue, Beijing, Tai 'an, Qingdao, mountainous areas in western Hebei, mountainous areas in western Hubei (Enshi Prefecture, Changyang area) and Henan are all distributed, and Ankang is cultivated.
