Metasequoia glyptostroboides
Metasequoia glyptostroboidesGoldRush' is a cultivated variety of Metasequoia glyptostroboides developed in recent years. Deciduous trees, fast-growing, sexually strong, reddish-brown bark; leaves flat, linear, opposite in 2 rows on short branches; new leaves are golden in spring, summer and autumn of the year.
Metasequoia glyptostroboides are mostly introduced from Japan, which have strict requirements for microclimate, high requirements for air humidity, and like water and wet climate. At present, it has been introduced in Beijing, Jiangsu, Shanghai, Zhejiang and other places. The experiment shows that the introduction performance is poor in some areas of Beijing, while the Metasequoia glyptostroboides introduced in Shanghai, Jiangsu and Zhejiang has strong adaptability, fast growth, straight trunk and beautiful tree shape. the leaf color is stable, and the three-year-old seedlings can reach more than 3 meters high. Multi-use cutting propagation can be carried out in four seasons, and the survival rate is higher.
Metasequoia glyptostroboides is resistant to water and moisture, and it is an excellent greening tree species in plain and lake area, but as a colored leaf tree species, it has a broad development prospect in East China.

Semi-lignified softwood cuttings of Metasequoia glyptostroboides?
The seedling raising technique of semi-lignified softwood cuttings of Metasequoia glyptostroboides is: semi-lignified cuttings can also be used to raise seedlings in autumn, because at this time the branches have high maturity, winter buds have been formed, and there are no more branches in the same year after cutting. And only finish taking root. At the same time, with the further development of winter buds, the stem of seedlings will be more substantial, and an independent seedling transplanting culture can be formed when sprouting in spring. Autumn semi-woody branch cutting, intensive management time is short, unit area can be dense more cutting, the yield is very high, so it is very popular. Autumn sowing time, from mid-August to early September, cut

Cultivation techniques of Metasequoia glyptostroboides in Jiangxi Province
Metasequoia glyptostroboides is an ancient and rare tree species originating in Hubei Province of China, which has been listed as a national first-class protected tree species. It is fast-growing, light-loving, cold-tolerant and adaptable, and has been introduced and cultivated in the north and south of our country. The origin is distributed at an altitude of 900-1500 meters, mainly growing in valleys, streams and mountain valleys with good drainage. However, in the low wetlands where the groundwater level is too high and long-term stagnant water, the growth is poor. Generally speaking, the river alluvial soil in the plain is better for introduction, while the hilly and mountainous areas grow vigorously in the mountain yellow soil, especially in mountain valleys and humid areas.
