Bamboo forest carbon sequestration capacity measuring and carbon sequestration capacity improving fertilizer preparation method

Abstract

The invention relates to a bamboo forest carbon sequestration capacity measuring and carbon sequestration capacity improving fertilizer preparation method, which comprises the following six steps: 1, test design: selecting a bamboo forest sample plot, setting and processing a test area, then sampling, determining and computing; measurement and computation of annual respiration carbon emission amount of bamboo forest: measuring soil respiration rate, computing greenhouse gas CO2 emission flux and CO2 emission amount in soil annular accumulated respiration and determining no-root respiration soil CO2 emission amount; 3, measurement and estimation of bamboo forest vegetation carbon storage; 4, measurement and computation of soil carbon storage; 5, computation of bamboo forest annual net carbon fixation amount; and 6, optimum fertilizer preparation for improving bamboo forest carbon sequestration capacity. Through fertilizer application according to the optimum fertilizer preparation scheme obtained in the method disclosed by the invention, the carbon sequestration capacity of the bamboo forest can be obviously improved, and the invention provides an effective and feasible novel scheme for solving the greenhouse effect caused by the increase of atmospheric CO2 concentration.

Description

【Technical field】 [0001] The invention relates to the measurement and calculation of carbon storage and carbon discharge in forestry, and a fertilizer compounding method for increasing vegetation carbon storage and reducing soil carbon discharge. 【Background technique】 [0002] An increase in the concentration of atmospheric carbon dioxide will directly lead to an increase in the absorption of long-wave radiation from the sun by the atmosphere, causing a rise in global temperature and causing severe climate fluctuations. The rapid melting of the polar permafrost ice has greatly reduced the land area, threatening the living safety of humans and land creatures. Therefore, reducing carbon dioxide emissions has become a global research hotspot. [0003] The aboveground part of the forest vegetation carbon pool stores 80% of the global aboveground carbon storage, and the forest soil carbon pool stores about 40% of the global soil carbon storage. Therefore, forests play a very i...

Problems solved by technology

Most of the previous experiments on fertilizers in moso bamboo forests focused on the effect of fertilization on the yield of bamboo and bamboo shoots, but rarely involved the research on the effect of fertilization on soil carbon pool and soil respiration carbon release, let alone the effect of fertilization on the carbon sink capacity of the whole moso bamboo forest ecosystem Research
