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: Pingjiang County, Hunan Province. The purpose of cultivation is to cultivate medium-diameter trees. The average stand diameter is expected to be 12cm, so the optimum density is 2517 trees / hm 2 .

[0057] (1) Plant the annual seedlings of Quercus qinggang with a row spacing of 2m*2m, and keep 2500-2550 Quercus qinggang forest trees per hectare.

[0058] (2) Fir trees are mixed between rows, the row spacing between Chinese fir trees is 2m*2m, and there are 2500-2550 fir trees per hectare. figure 1 It is a schematic diagram of mixing Quercus qinggang and Chinese fir in Example 1 (O is Quercus qinggang, X is Chinese fir).

[0059] (3) Appropriately trim side branches, improve the light-transmitting environment in the forest, and promote the growth of the main trunk.

[0060] (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 of the forest stand exc...

Embodiment 2

[0063] Location: Pingjiang County, Hunan Province. The purpose of cultivation is to cultivate medium-diameter trees. The average stand diameter is expected to be 18cm, so the optimum density is 1678 trees / hm 2 .

[0064] (1) Plant the annual seedlings of Quercus qinggang with a row spacing of 2m*3m, and keep 1650-1700 Quercus qinggang forest trees per hectare.

[0065] (2) Mix Chinese fir between rows at a ratio of 1:1, and keep 1650-1700 Chinese fir per hectare. figure 2 It is a schematic diagram of mixing Quercus qinggang and Chinese fir in Example 2 (O is Quercus qinggang, X is Chinese fir).

[0066] (3) Appropriately trim side branches, improve the light-transmitting environment in the forest, and promote the growth of the main trunk.

[0067] (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 of the stand exceeds 0.77, thinning or cutting of Chinese fir w...

Abstract

The invention relates to the field of forest plantation and specifically relates to a cultivation method for medium-diameter cyclobalanopsis glauca. The method comprises the following steps: (1) planting cyclobalanopsis glauca annual seedlings at the planting spacing from 2-3m*2-3m and planting 1259-2517 plants of cyclobalanopsis glauca in each hectare area; (2) uniformly planting firs between the plants and / or rows of the cyclobalanopsis glauca, wherein the firs are annular fir seedlings; (3) after the closing of crops, periodically checking the canopy density and intermediately cutting or stumping the furs if the canopy density exceeds 0.77; (4) repeating the step (3), clearly cutting when the average diameter of cyclobalanopsis glauca is 12-24cm. According to the method provided by the invention, the standing forest growth is quick, the closing is early, the production process is easy to control and the intermediate cutting cost is lower.

Description

technical field [0001] The invention relates to the field of artificial afforestation, in particular to a method for cultivating medium-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 textu...
