It is well known that white pine is also known as white bone pine, belonging to the Pinus genus of the pine family, and is a unique species in China. The city of Lantian in Shaanxi Province has large white pine planting bases. It is distributed in other provinces across the country. The seedlings of white pine in Shaanxi have a variety of shapes, are lush and upright, and have become one of the excellent tree species for urban and courtyard greening in the region.
White pine is an evergreen tree, with smooth bark on young trees, gray-green in color, and irregularly shedding bark on old trees to expose the pink inner bark, complemented by the lush green canopy, which is very beautiful. White pine has strong resistance to sulfur dioxide and soot pollution and has long been considered an excellent tree species for landscaping in the North China region.
Generally, white pine seedlings are distributed on cool, acidic stone mountains and grow in deep, fertile calcareous or loess soil environments. White pine seedlings are afraid of waterlogging, so the seedling site should be flat, well-drained, irrigated, flat terrain, and deep loamy or sandy loam soil. Heavy clay soil, saline-alkali soil, and low-lying waterlogged land are not suitable for seedbeds. White pine has deep roots and a long lifespan, reaching several centuries. The wood of white pine is generally used for building materials, furniture, stationery, and other purposes.
The germination treatment of white pine seeds is also a science. It is recommended to use Bordeaux mixture to disinfect the seeds, soak the seeds in warm water or mix them with sand for stratification before sowing, and sow when 50% of the seeds have opened. It usually takes 15 to 20 days for the seeds to germinate. Sowing is best 10 to 15 days after the soil thaws. Thoroughly water the seedbed before sowing and use wide-row broadcasting or broadcasting. Finally, build a small arch shed on the seedbed to increase temperature and humidity, improving the germination rate. No watering is needed before the seedlings emerge.
Usually, white pine seedlings grow slowly and should be densely planted. If larger seedlings need to be cultivated, they will need to be transplanted 2 to 3 times before planting. Two-year-old seedlings can be transplanted with soil in early spring before the terminal bud has germinated, with a spacing of 20 to 60 centimeters. Remember not to damage the terminal bud and water reasonably after planting. Generally, it takes 4 to 5 years for the seedlings to grow, then they can be transplanted again with soil balls. After the white pine seedlings have survived, keep the soil around the roots loose, strengthen management, and promote the rapid growth of strong seedlings.
