Manual regulating technology for promoting sprouting regeneration of quercus semicarpifolia type plant

Abstract

The invention discloses regulating technology for promoting sprouting regeneration of a quercus semicarpifolia type plant. Aiming at the defect that the prior art is not suitable for production practice, the invention provides manual regulating technology for promoting the sprouting regeneration of the quercus semicarpifolia type plant, which is used for fulfilling the dual aims of maintaining sustainable regeneration capability of a quercus semicarpifolia forest and meeting the demands of local peasants and herdsmen on daily life energy in quercus semicarpifolia forest culturing management. In the technical scheme, controlled intermediate cutting is applied to the quercus semicarpifolia forest and cutting intensity is between 60 and 80 percent. Simultaneously, main factors which affect the sprouting regeneration of the quercus semicarpifolia type plant are controlled in a quantitative index range so as to promote the sprouting regeneration of the quercus semicarpifolia forest and control the regeneration direction of the quercus semicarpifolia forest. The relation between the logging regeneration of the quercus semicarpifolia forest and the logging amount of local residents can be balanced effectively, the contradiction between man and earth is solved and ecological and social benefits are achieved. The technology is easy to operate and particularly suitable for guiding the peasants and the herdsmen in mountain areas.

Description

technical field [0001] The invention relates to a control technology for promoting plant regeneration, in particular to an artificial control technology for promoting the germination and regeneration of alpine oak plants, which belongs to the field of forestry. Background technique [0002] Quercus L. belongs to the Fagaceae family and is distributed in northern temperate and tropical mountains. Quercus is one of the important forest trees, and it is also a tree species with multiple functions such as wood, charcoal, dye, cork, and tussah silkworm breeding. It is distributed in all provinces in the north and south of my country. Studies in many Quercus distribution areas, including North America, Europe, and the Himalayas, have confirmed that Quercus plants generally have poor seed regeneration ability. Insect pests lead to stunted development, and when they mature, they face the feeding pressure of animals, coupled with the influence of microenvironment, fire disturbance, ...

AI Technical Summary

Problems solved by technology

Long-term continuous random human disturbance leads to the decline of the self-compensation and adjustment ability of Quercus alpine, and the retrograde succession and degeneration of Quercus alpine shrubs to short shrubs, resulting in the decline of ecological functions of Quercus alpine forests, which has increasingly become the main problem facing forest cultivation in Hengduan Mountains. one

However, because most of the distribution areas of Quercus alpine in Hengduan Mountains are areas inhabited by ethnic minorities such as Tibetans, the social and economic development is backward, and they belong to typical poor mountainous areas. Local farmers and herdsmen will still rely on Quercus alpine plants for a long time Therefore, how to use the strong germination ability of Alpine Quercus to solve the problem of not only meeting the energy needs of local farmers and herdsmen, but also promoting the germination and renewal of Alpine Quercus and the stability of the community. The resolution of regional human-land conflicts and the construction of regional ecological security are of great significance

[0005] The academic paper "Growth performance of Quercus acutissima after planting with different regeneration methods" (Lu Zhengmao et al. 2003. Jilin Forestry Science and Technology, 32(5): 18-21.) discloses that the regeneration of Quercus acutissima is better than the regeneration of seedlings and sowing. It has a higher survival rate, but the method of "selecting 5-10 years old Quercus japonica forests for stubble" used in this study is too simple and can only be implemented in experiments and cannot be applied to production practice.

Master's degree thesis "Comparative Study on Plant Community Structure in the Restoration Process of Degraded Ecosystem in the Upper Minjiang River" (Liu Wensheng. 2003. Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences) disclosed the research that the height of residual tree stumps of Quercus liaotungensis is directly proportional to the number of sprouting branches As a result, the research results only illustrate some trends, and still cannot be effectively applied to production practice
