Method for improving fixation of carbon in arid desert region by using rhizome sprouts

Abstract

The invention relates to a method for improving the fixation of carbon in the arid desert region by using rhizome sprout. According to the method, the rhizome sprouts and pruned root sprouts of plants are used to rapidly increase the aboveground vegetation coverage and the fixation of the carbon by plants. The seeds of apocynum venetum, alhagi and halimodendron halodendron are sowed in lines manually, water is supplemented manually to promote the sprouting and rejuvenate the seedlings, and the roots of apocynum venetum, alhagi and halimodendron halodendron and the roots of the deep-rooted populus diversifolia, tamarix chinensis and sacsaoul at the periphery of apocynum venetum, alhagi and halimodendron halodendron are pruned to sprout. The growth of the seedlings of plants is promoted effectively, the aboveground vegetation coverage is increased rapidly, the inorganic carbon such as CO2 in the air is absorbed and fixed under the action of photosynthesis of plants, the fixation of the carbon in the saline-alkali land is improved effectively, the vegetation coverage level of the arid desert region with sparse aboveground vegetation, the amount of precipitation of less than 200mm and the amount of evaporation of more than 2,000mm is increased, the carbon absorption capacity of the region is improved, and the carbon accumulation amount of the region is increased.

Description

technical field [0001] The invention relates to a technology for improving carbon sequestration in arid desert areas, in particular to a method for improving carbon sequestration in arid desert areas by utilizing rhizome sprouting tillers. Background technique [0002] Global climate change is the biggest environmental problem faced by mankind so far, and it is also one of the most complex challenges faced by mankind in the 21st century. It is listed as the top ten environmental problems in the world. Before the industrial revolution, the carbon exchange between the land and the atmosphere was almost in balance. Since the industrial revolution, due to the burning and use of fossil fuels such as coal and oil, a lot of inactive carbon has been released, and vegetation such as forests and grasslands The destruction not only releases carbon into the atmospheric system, but also causes the continuous weakening of the carbon sequestration capacity of the biosphere, resulting in th...

AI Technical Summary

Problems solved by technology

[0005] Research on carbon sequestration technology in desert areas is relatively weak. At the same time, due to the development of animal husbandry, livestock grazing has caused serious loss of biomass in shallow root shrubs and aboveground parts of herbaceous plants, and system renewal has also been greatly affected. The ability to absorb and fix inorganic carbon in desert areas has been weakened; at the same time, the technology of cutting roots and sprouting tillers to promote plant regeneration is mostly used for mature deep-rooted plants to achieve the purpose of forest ecosystem restoration. The technology of root pruning and tillering of herbs and shrubs to increase biomass has not been reported, and the technical system is still immature
