Problems solved by technology

Existing research on Quercus microphylla is mainly as follows: "Zhejiang Flora (Wang Jingxiang, 1992)", "Ecological Geography of Quercus variabilis, Quercus variabilis, and Quercus microphylla (Jiang Zeping, 1991)" and "Quercus variabilis, Quercus variabilis, Quercus microphylla, A brief report on the cutting propagation of Quercus chinensis and Lithocarpus (Hu Wanyi, 1992), "The colonization and growth of 8 native tree species in iron ore wasteland (Hu Dan, 2007)" and "The effect of nitrogen addition on the growth of different tree species of Quercus genus in the subtropical zone and the short-term impact of biomass allocation (Wang Xiaorong, 2014), but there is a lack of systematic research on the growth and tree fruiting of Quercus microphylla forests, especially the lack of mature technologies for the production and management of oak forest timber and seeds
In addition, the research on dual-use forests mainly includes "Research on Appropriate Density Control Technology of Korean Pine Fruit and Wood Dual-use Forests (Jia Yun, 2006)", which adopts technical measures such as stand density adjustment and truncating to promote tree hardening to improve timber diameter growth and Fruiting effect, but it uses cutting to promote tree fruiting, not a healthy cultivation close to natural forest

Embodiment 1

[0028] The method for cultivating the dual-purpose forest of Quercus microphylla provided in this example was implemented in the Shuangfeng forest area of ​​Tiantong Forest Farm, Yinzhou District, Ningbo City, Zhejiang Province; the experiment period was from 2002 to December 2015.

[0029] Shuangfeng Forest Area 87hm 2 , 30-240m above sea level, the forest area has convenient transportation. The forest tree species are mainly broad-leaved trees such as masson pine, fir, cedar, and Schima superba, and most of them were artificially created in the late 1950s and 1960s. Among them, 2hm of oak plantation 2 , for afforestation in the winter of 1959. The afforestation land was originally barren shrubs, bamboo clumps and graveyards. The shrubs and bamboo clumps were cleared, the tombs were demolished, the forest land was leveled, and holes were planted. After afforestation, tending is carried out twice a year for 4 consecutive years; thinning tending is carried out in the 12th yea...

Embodiment 2

[0060] The implementation site is the western mountain block of Wangbiao Mountain in Shuangfeng Forest District, Yinzhou District, with an altitude of 50m and a slope facing south with a slope of ≤12°. In December of the same year, a small-leaf oak forest was artificially planted. After the selection of forests, young forests and mature forests were tended. In 1994, after the special long timber for shipbuilding was harvested, the undergrowth and regeneration layer forests were partially damaged, and the canopy density was reduced to 0.55. Composed of 9 lobular oaks and 1 camphor tree. The closure was introduced in 1996, allowing the forest community to recover.

[0061] From February 2002 to December 2015, the method was the same as in Example 1 by selecting healthy and near-mature stands, controlling stand density, forest land surface management, dry material accumulation growth management and seed production management.

[0062] According to a 20m×20m sample plot survey of...

Abstract

The invention discloses a method for cultivating a seed and timber dual-purpose forest of quercus chenii and belongs to the technical field of forestry forest management. The method comprises the steps, i.e., technical measures of carrying out quercus chenii forest stand selection, carrying out tending and intermittent cutting of forest and stand density regulation and control, carrying out forest land floor governing, carrying out stem timber accumulated growth management and carrying out seed production management, thereby finally creating the healthy and high-value quercus chenii seed and timber dual-purpose forest from an ordinary commodity timber forest. According to the method, the seed output of forest trees can be increased obviously, the years for cultivating large-diameter timber are shortened, the quality of the forest trees is improved, and the production potential is increased; and compared with the prior art, the method has the remarkable advantages that the amount of growing stock of large-diameter-class standing wood us large, the volume of seeds is large, the method is simple, practical and safe and is high in operability, and the like.

Description

technical field [0001] The invention relates to forestry forest cultivation, in particular to a method for cultivating a dual-purpose forest of Quercus microphylla, in particular to a method for cultivating a dual-purpose forest for tree growth and seed production of Quercus microphylla. Background technique [0002] Quercus chenii is a large deciduous tree of the Fagaceae Quercus genus, which has the characteristics of fast growth, strong adaptability and long life. The trunk of this kind is straight and round, the wood is hard, wear-resistant and rot-resistant, and the material is excellent, which can be used for construction, shipbuilding, furniture, etc.; the shell and seeds are the raw materials of forest by-products; Majestic in appearance, it is an excellent wind-resistant, drought-resistant, greening and afforestation tree species. Quercus microphylla is mainly distributed in Zhejiang, Jiangsu, Anhui, Jiangxi, Hubei and other provinces. It is often born in hills and...
