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.
