Embodiment 1

[0056] Location: Suining County, Hunan Province. The purpose of cultivation is to cultivate large-diameter timber. The average forest diameter is expected to be 28cm, so the optimal density is 1079 trees / hm 2 . figure 1 The schematic diagram of the mixture of Cyclobalanopsis glauca and Cunninghamia lanceolata in this embodiment, where Ο is Cyclobalanopsis glauca and X is Cunninghamia lanceolata.

[0057] (1) The annual seedlings of Cyclobalanopsis glauca are planted with a row spacing of 3m*3m, with 1,100 Cyclobalanopsis per hectare.

[0058] (2) Inter-plant and inter-row mixed fir, so that the row spacing between Cyclobalanopsis glauca and fir, and fir and fir is 1.5m*1.5m, 3250-3300 fir per hectare.

[0059] (3) After afforestation, it should be managed more frequently and cultivated continuously for 5 years to promote forest canopy closure.

[0060] (4) Prune the side branches appropriately to improve the light transmission environment in the forest and promote the growth of the mai...

Embodiment 2

[0065] Location: Suining County, Hunan Province. The purpose of cultivation is to cultivate large-diameter timber. The average forest diameter is expected to be 25cm, so the optimal density is 1208 trees / hm 2 .

[0066] (1) Cyclobalanopsis oak and fir interplanted at a ratio of 1:1, with a row spacing of 2m*2m, retaining no less than 1210 Cyclobalanopsis oak trees per hectare, and 1210 fir per hectare. figure 2 It is a schematic diagram of the mixture of Cyclobalanopsis glauca and fir in Example 2 (O is Cyclobalanopsis chinensis and X is fir).

[0067] (2) After afforestation, it should be managed more frequently and cultivated continuously for 5 years to promote forest canopy closure.

[0068] (3) Prune the side branches appropriately to improve the light transmission environment in the forest and promote the growth of the main stem.

[0069] (4) After afforestation canopy closure, survey the canopy closure every 2 or 3 years and keep the stand canopy closure at 0.75. If the stand ca...

Abstract

The invention relates to the field of artificial afforestation, in particular to a method for cultivating large-diameter cyclobalanopsis glauca. The method is characterized by comprising the following steps that (1) one-year-old seedlings of cyclobalanopsis glauca are planted with the plant row spacing of 2-3 m*2-3 m, and 888 to 1259 plants of cyclobalanopsis glauca are planted per hectare; (2) one-year-old fir seedlings are planted between plants and/or rows of the cyclobalanopsis glauca forest; (3) after closing of forest stands, the canopy density is periodically examined, and if the canopy density of forest stands exceeds 0.77, firs are thinned or stumped; (4) the step (3) is repeated, and when the average diameter of forest stands of cyclobalanopsis glauca is larger than or equal to 24 cm, clear cutting can be carried out, and wood is obtained. According to the method, growing of forest stands is rapid, closing is early, the production process is easy to control, and the thinning cost is low.

Description

Technical field [0001] The invention relates to the field of artificial afforestation, in particular to a method for cultivating large-diameter Cyclobalanopsis glauca. Background technique [0002] Among the main dominant species of natural arbor forests in the country, oak species have an area of ​​16.1 million hectares, an area ratio of 13.70%, a volume of 1.281 billion cubic meters, and a volume ratio of 10.42%. Both the area and the volume rank among the country's largest dominant species. [0003] Cyclobalanopsis glauca is also called "thick wood". Cyclobalanopsis glauca belongs to the evergreen tree of the Fagaceae family. It is one of the most widely distributed evergreen broad-leaved trees in China. It is divided into "red thick" and "white thick" according to the wood color. . Historically, "camphor, catalpa, phoebe, and linden" were also called "four famous trees in the south of the Yangtze River", especially "Nan and linden" because of their hard wood, high strength, be...
