Seedling cutting methods of Metasequoia glyptostroboides
The cutting method of Metasequoia glyptostroboides seedlings: cutting along with cutting from late March to early April. Cut cuttings with 1-2-year-old seedlings or new shoots germinated in the same year. The lower end of the cuttings was treated with naphthalene acetic acid at a concentration of 0.5 ppm and soaked for 20 to 24 hours to promote rooting and survival. About 120 plants per square meter. Keep the nursery bed moist after insertion. The new roots germinated for about 40 days, and rarefied human feces and urine were applied every 10 days for 3 to 5 times. In June, a small amount of nitrogen fertilizer can be applied many times, 3 to 4 kilograms of urea per mu, mixed with water. In the first ten days of August, phosphorus and potash fertilizer was applied once, 30 jin of compound fertilizer was poured with water per mu, and 40 jin of phosphate fertilizer was scattered on the seedbed.

At the end of the trunk, the base is often inflated and the crown is conical. It is a precious tree species endemic to China. It belongs to ancient relict plants. Metasequoia glyptostroboides is adaptable, but likes warm and humid climate, deep, fertile and moist soil. Drought, barren, low temperature and saline-alkali are not conducive to the growth of metasequoia. Metasequoia wood has straight texture, light and soft material, small difference in shrinkage, and easy to process.
