Cultivation techniques of Metasequoia goldenleaf

Metasequoia glyptostroboides is a large deciduous tree of the genus Metasequoia of Taxodiaceae. Metasequoia glyptostroboides trunk straight and straight, magnificent tree shape, golden leaves, autumn leaves orange, is a famous garden ornamental tree. Metasequoia glyptostroboides can be found in parks, courtyards and lawns. Solitary planting, row planting or group planting in green space; it can also be planted in pieces to create scenic forests and adapt to evergreen cover plants; it can also be planted in front of buildings or used as street trees with good results. Metasequoia glyptostroboides has a certain resistance to sulfur dioxide, and it is also a good tree species for greening in industrial and mining areas.

Metasequoia glyptostroboides can grow well between 20 and 40 degrees north latitude. East China, Central China and North China can be cultivated except Inner Mongolia.

Light-loving species of Metasequoia glyptostroboides. Like warm, humid climate, can withstand the severe cold of-35 degrees Celsius, but can not bear the dry cold in winter, the seedlings are slightly resistant to shade. Like deep and fertile acid soil, strong alkali resistance, can grow in light saline-alkali soil with a salt content of less than 0.2%. Deep, fertile, moist sandy loam grows best in valleys and soil layers with a mild and humid climate. It is required to be moist and well drained, not resistant to waterlogging, and sensitive to soil drought.

The cultivation of Metasequoia glyptostroboides should choose a place with wet and good drainage. Because of the winter drought in North China, it is necessary to choose a place to take shelter from the wind and the sun, and young trees should also build wind barriers to prevent the cold. The survival rate of planting is high in spring, and it is planted along with it. If long-distance transportation is needed, the seedlings should be soaked in water before planting to make them absorb enough water and promote survival. Small seedlings need to be stained with mud, while large seedlings need to be planted with soil balls. Dig big holes and apply basic fertilizer before planting, so as not to hurt the roots. Water thoroughly after planting. Topdressing fertilizer can be applied during the growing period, and it can be pruned properly at the seedling stage. 4, do not prune after 5 years, so as not to destroy the tree shape. Red spider moth is easy to occur in summer drought, so attention should be paid to prevention and control.
