Breeding methods
Propagation can be done through seeds or cuttings.
cultivation techniques
Seed collection and seedling cultivation: Select mature and robust mother trees for seed collection. When the cones turn yellow brown and the scales are slightly cracked, they can be collected. After rolling the cones back and forth, spread them thinly and expose them to sunlight. Wait for the seeds to crack and the seeds to come out. Rub off the wings of the seeds, clean them with wind and remove impurities, store them dry, and sow them in the next spring.
Nursery He: Choose sandy loam soil that is convenient for irrigation and has shorter sunlight. Dig deeply with a fine rake, pick up the gravel residue, apply sufficient base fertilizer, carefully prepare the soil, make the bed surface neat, and sow or scatter in strips. The sowing rate per acre is 10 kilograms for withdrawal and 4 kilograms for strip sowing. After sowing, cover with yellow soil, with a thickness of no visible seeds, and cover with straw. After the sprouts are exposed to the soil, remove the covering. During the seedling stage, weed control should be carried out, appropriate fertilization should be applied, and attention should be paid to preventing pest infestations. 1% equal amount of Bordeaux mixture should be sprayed every half month. Water should be poured in the early morning, and in the hot summer, a canopy should be set up for shade, and seedlings should be spaced according to their needs. The following year, a garden transplant will be carried out. Hemlock, which grows slowly during its growth period, needs to be cultivated in the nursery for 3-5 years before it can be planted in the nursery.
Afforestation method: Taxodium species with positive deep roots. But it requires a warm and humid climate, prefers acidic or neutral sulfur pine, fertile yellow soil, and yellow brown soil mountainous areas. From the natural forest of Mount Wuyi Mountain, it is distributed on the south and north slopes, but the sunny slope is more prosperous. Naturally planted seedlings up to 6 or 7 years old can still tolerate shade, and as they grow older, they require increased light exposure to prevent poor growth. The selection and planning of afforestation sites should first consider high-altitude mountainous areas, choose sunny or semi sunny slopes, cut and burn mountains, fully cultivate and dig holes, with hole sizes of about 50 x 60 centimeters. When planting hemlock trees, great attention should be paid to their survival rate. One of the key points is to avoid damaging the root system when digging up the tall trees in the nursery to avoid affecting the survival rate of afforestation, and to plant them as soon as the seedlings are raised. Choose rainy or light rainy days to plant trees. Before planting, dip the roots in mud, make a row of roots, plant straight, and tighten.

Nurturing and management: Due to the slow growth of hemlock and its ability to provide shade during childhood, co nurturing and management can be combined with forest and grain cultivation, but the recommended intercropping period is generally 3-4 years. After intercropping is stopped, annual tillage and weeding must also be carried out. After the trees are closed, according to the growth of weeds and the needs of soil management, the cutting and loosening of soil are carried out in rotation. The trees begin to differentiate, and timely thinning is carried out. According to the principle of "leaving large and small, leaving strong and weak, leaving sparse and dense", compressed trees, trees damaged by pests and diseases, wind blown trees, etc. are cut down.
