Problems solved by technology

[0004] The present invention aims at the prominent problems of low productivity and poor ecological benefits of large-area artificial forests. The purpose of the present invention is to provide a method of using understory plants to fix carbon and increase sinks through rational allocation of understory plants. Rhizomes, strong germination, fast reproduction, fast decomposition and turnover of fleshy rhizomes, combined with breeding technology and understory branch rapid forestation technology to integrate a method for carbon sequestration and sequestration of understory plants

Embodiment 1

[0032] Cultivation of first year cardamom seedlings:

[0033] (1) Seed collection: From August to September every year, when the cardamom seed coat turns yellow, select plants that grow vigorously and are free from diseases and insect pests, and pick the fruits and keep them as seeds.

[0034] (2) Seed treatment: Peel off the peel as soon as possible after harvesting the fruit, take out the lumpy seeds, mix them with fine sand in equal proportions, rub the seeds into granules, rub them thoroughly, and then soak the seeds in clean water for 12 hours.

[0035] (3) Seedling site is established: select sunny, well-drained, plots near water sources, deep plow the whole furrow, and plant seedlings in a ratio of 5-10wt% by substrate (cultivation soil and organic fertilizer are mixed in a mass ratio of 100:1) The field soil and the substrate are evenly mixed, beaten and raked, and the seeds are evenly spread, covered with a layer of culture soil with a thickness of 1cm, and covered wi...

Embodiment 2

[0039] Mazhan Acacia Forest in a field experiment station.

[0040] (1) Choose the decaying Acacia japonica forest, and cut down all the shrubs and grasses under the forest.

[0041] (2) In the spring of the second year, the cardamom seedlings cultivated in embodiment 1 are planted under the Acacia japonica forest with a canopy density of 30-60%, and the horizontal ditch is dug along the contour line for planting, with a row spacing of 50 × 50cm , the ditch depth is 20-30cm, and the planting ditch is loosened once half a year after planting.

[0042](3) In the spring of the third year, select a strong plant as the mother plant, dig out the fleshy massive underground rhizome with buds of the mother plant, divide the fleshy massive underground rhizome into individual plants, and keep 8-10cm in each section, at least 1-2 bud points to obtain a single plant of fleshy massive underground rhizome; or in late spring and early summer, dig out the fleshy massive underground rhizome of...

Abstract

The invention discloses a quick carbon fixation method for underbrush by katsumada galangal seeds. The quick carbon fixation method comprises the following steps of collecting katsumada galangal seedsin August to September of the first year, performing sowing, and raising seedlings; planting the katsumada galangal seedlings at underbrush of certain crown density in the next spring, digging horizontal ditches along the contour line, and performing planting; and after the third year, performing plant dividing of chlophylly block subterraneous roots and stems of the katsumada galangal, and performing transplanting on the katsumada galangal divided plants in spring, summer and late autumn continuously, to realize continuous plant dividing and transplanting without raising the seedlings. The method is simple in plants, high in adaptability, and easy to operate, and the coverage rate can 50% in the same year; and besides, except the dry season, continuous plant dividing for planting can beperformed, so that the area can be quickly enlarged, the carbon fixation capacity and the soil fertility of forests can be improved, the ecological benefits are increased, and the purpose of sustainable management of forestry `can be realized.

Description

technical field [0001] The invention belongs to the technical field of forestry and forest management, and in particular relates to a method for quickly sequestering carbon under a cardamom forest. Background technique [0002] As an important part of the forest ecosystem, understory plants affect above-ground ecological processes such as seedling regeneration, forest succession, species diversity, forest productivity, and soil and water conservation. They also affect root system and litter decomposition, soil nutrient cycle, and soil moisture. Underground ecological processes. Although it plays an important role in ecology, it is often easily overlooked due to the relatively small proportion of biomass in the total biomass. In order to facilitate forestry operations, traditional forestry operations mostly use burning and chopping to remove understory plants, resulting in serious ecological problems such as atmospheric environment, soil erosion, nutrient leaching loss, and ...
