Matters needing attention in tending and Management of Metasequoia glyptostroboides
It should be nurtured in time after afforestation. Watering in April and May is the key to survival. When planting big seedlings, special attention should be paid to drought resistance in the hot season. Weeding and loosening soil were carried out two or three times a year, and the tending effect was significant from May to June and from August to September. Two years later, it is necessary to apply fertilizer before germination in spring. Generally speaking, pruning is not necessary before the forest is formed, but it should be pruned moderately after the forest is established. When the tree is 6 to 10 meters high, the pruning height is 1/4 to 1/3 of the tree height; when the tree height is 10 to 15 meters, the pruning height is 1/3 to 1/2 of the tree height.

Rapid Seedling raising technique of Metasequoia glyptostroboides
1. Soil preparation and bed preparation are required to raise seedlings with conventional small seeds. Bed width 100cm, high 20cm, slightly suppressed after leveling, sprinkled with 3G pesticide per square meter to control underground pests and earthworms. The nursery bed for raising seedlings will be ready before the middle of February. Every 500g seeds will be sown in the 20m2 seedbed and can be used for field transplanting in the future. The field transplanting seedbed will be ready by late March. two。 Timely sowing time is the key. Temperature has a great influence on the underground part of seedlings, and lower air temperature can inhibit the growth of main roots and promote the growth of main roots.
