Problems solved by technology

[0005] At present, my country's artificial cultivation of Quercus candica is based on experience to estimate the spacing and planting, and most of them are planted in pure Q. cannulae forests, or other trees are planted in random intervals in a single species of Quercus candosa, and the side branches of Quercus cannulae grow rapidly, which seriously affects the dry wood of Quercus candosa. Biomass and stand quality, economic yield is generally not high

Embodiment 1

[0056] Location: Suining County, Hunan Province. The purpose of cultivation is to cultivate large-diameter trees. The average stand diameter is expected to be 28cm, so the optimum density is 1079 trees / hm 2 . figure 1 It is a schematic diagram of the mixture of Quercus qinggang and Chinese fir in this embodiment, wherein O is Quercus qinggang, and X is Chinese fir.

[0057] (1) Plant the annual seedlings of Quercus qinggang with a row spacing of 3m*3m, 1100 trees of Quercus qinggang per hectare.

[0058] (2) Inter-plant and inter-row mixed Chinese firs, so that the row spacing between Quercus qinggangensis and Chinese fir, and between Chinese fir and Chinese fir is 1.5m*1.5m, and there are 3250-3300 Chinese fir trees per hectare.

[0059] (3) After afforestation, intensive management should be carried out, and continuous tending should be carried out for 5 years to promote stand closure.

[0060] (4) Appropriately trim side branches, improve the light-transmitting environmen...

Embodiment 2

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

[0066] (1) Mix Quercus qinggang and Chinese fir at a ratio of 1:1, the row spacing between plants is 2m*2m, keep not less than 1210 oak trees per hectare, and 1210 fir trees per hectare, figure 2 It is a schematic diagram of embodiment 2 Qinggangdong and Chinese fir mixed (O is Quercus Qinggang, and X is Chinese fir).

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

[0068] (3) Appropriately trim side branches, improve the light-transmitting environment in the forest, and promote the growth of the main trunk.

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

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 oak oak. Background technique [0002] Among the main dominant species of natural arbor forests in the country, the area of ​​oak species is 16.1 million hectares, accounting for 13.70% of the area, and the volume is 1.281 billion cubic meters, accounting for 10.42%. [0003] Cyclobalanopsis glauca, also known as "Cyclobalanopsis glauca", is an evergreen tree belonging to the Fagaceae family. It is one of the most widely distributed evergreen broad-leaved tree species in China. According to the color of the wood, it is divided into "red thick" and "white thick". . Historically, "Camphor, Catalpa, Nan, and Cinnamon" were collectively known as the "Four Famous Woods in the South of the Yangtze River". In particular, "Nan and Cinnamon" were famous and valuable because of their hard, solid wood, high strength, beautiful color and textur...
