 South China fir is a fast-growing specialty timber species. Which is characterized by fast growth, high yield, wide use. Garden full of straight stem form, wood texture, straight, light weight and tough, for strength, fragrance, insect resistant, is an important timber of goods. The cultivation techniques are presented for reference. 

 First, the seed harvest fir March flowering bulbs in early November by the blue green to brown when you can harvest. Best seed trees or seed orchard seed, also choose 15 to 30 years old, plus trees grow well on the seed. Cut bulbs with high sticks, put the ball fruit drying yard, the sun exposure, cone scales open, you can repeatedly drive cone, so that the seed falls out from the cones, and then collect pure, good use of gunny bags, put ventilated and dry warehouse into standby. The seed cone was 3 to 5%, 13 grams of seed weight, germination rate of 40%. 

 Second, seedling selection short sunshine, water resources facilities, deep soil, soil fertility, live, the permeability of sandy loam to do a good seedbed. Made of high-bed, bed height 25 cm, 120 cm wide bed, crushing the soil requirements, bed flat, smooth channel. February sowing, the use of sow, sow 5 kg per 667 square meters, covered by yellow soil after sowing, 1.5 to 2.0 cm thick. Timely weeding tillage, appropriate thinning, weekly spraying Bordeaux mixture 1 0.5%, to prevent the occurrence of disease. 6 months ago to enhance drainage, 7 August drought should pay attention to irrigation, 9 months later to stop fertilizing irrigation. Year up to 40 cm above the height, diameter 0.5 cm or so, can Chupu planting next spring. 

 Third, choose deep soil planting site preparation, loose texture, fat moist sunny or semi-live in the lower part for the plantation of Yangcheng. To clear the bushes before soil preparation and weed. 20 degrees below the slope, digging can be cultivated all the land, slopes above 20 degrees can be massive with Ken digging or digging soil preparation. Asked 50 cm deep hole, hole 70 cm wide, hole from 1.7 × 2.0 meters. To backfill crushing the topsoil and 20 cm above the ground. Qimiao early spring planting, planted one per hole, in order to stretch rhizosphere, Miao body upright, proper planting depth, step tight soil, tillage training stump. In case of dry weather, planting, roots should be pouring water. Barren soil of the plantation than should be Hunzai 1 / 3 of the pine seedlings, cedar pine mixed to form and promote forest to become useful. 

 Fourth, tending to the 2 year planting cultivation, 4 to 6 months between the weed block loose soil, 8 to 9 full month of weeding tillage. Started 2 1 ~ 2 times each year tending a forest canopy until the young trees. To 2 times after forest thinning. 8 ~ 10 years after planting, between the 1st cutting, after cutting to retain 170 per 667 square meters 200; 13 to 15 years for the 2nd cutting, cutting 120 to 160 retained. When thinning is necessary to follow "to small to stay big, go bad to stay good, stay close to the rare" principle. 20 years or so updates can be fully harvested. Updates can be added budding Zaimiao way to achieve low input high output. Fir fir fir seedlings for large seeds. Tel:
