摘要

全球对增加世界碳储量的兴趣倾向于多年生木本生态系统。但是,持续的土地短缺阻碍了这一目标的实现。因此,我们必须致力于探索可行的替代方案。香蕉作为潜在的碳封存物并没有引起研究人员的注意。因此,本研究旨在估计香蕉在印度不同邦作为潜在碳封存物的潜力。数据是在2021年1月至2022年12月期间从12个主要香蕉生产国收集的。在12个香蕉生产州的每个州抽样了100个香蕉园,涵盖了主要的香蕉种植(AAA, AAB和ABB)。采用异速生长方程,以假茎体积为异速生长参数,计算地上生物量和地下生物量。然后利用干重碳转换因子将异速生长方程得到的干重转化为碳。固碳量随香蕉的AAA值、AAB值和ABB值而变化。香蕉植株碳储量也很小,为2.573 ~ 6.407 t/ha,而土壤碳储量非常高,为39.55 ~ 77.14t /ha。在所有香蕉种植状态中,植物碳含量占土壤碳含量的比例仅为8.286%,土壤碳含量占91.714%。在全国范围内,香蕉作物每年吸收4862.7万吨碳,其中土壤碳占44798吨,植物碳仅占3828吨。尽管植物碳含量很少,但香蕉种植系统通过使更多的碳被固存到土壤中来丰富土壤,其数量与其他多年生种植园相当。

ANNUAL CARBON CAPTURE POTENTIAL IN BANANA GARDENS OF INDIA
The global interest in increasing the world's carbon stocks is skewed towards perennial woody ecosystems. But a continuous shortage of land stands in the way of achieving the goal. We must therefore aim to explore viable alternatives. The banana as a potential carbon sequester attracted little attention from researchers. Therefore, this study aimed at estimating the potential of bananas in different states of India as potential carbon sequesters. Data was collected from twelve major banana producers between January 2021 and December 2022. One hundred banana gardens were sampled in each of the 12 banana-producing states, covering the major bananas grown (AAA, AAB, and ABB). The above-ground (AGB) and below-ground (BGB) biomass were calculated using the allometric equation with pseudostem volume as the allometric parameter. The dry weight obtained from the allometric equations was then converted to carbon using a dry weight to carbon conversion factor. Sequestered carbon varied with the AAA, AAB, and ABB of bananas. Banana plant carbon stock was also found to be very small, ranging from 2.573 to 6.407 t/ha, compared with very high soil carbon ranging from 39.55 to 77.14t. In all the banana-cultivating states, the proportion of carbon contained in the plant to that in the soil was only 8.286 percent, and that of soil carbon accounted for 91.714%. At the national level, the banana crop sequestered 48.627 million metric tonnes of carbon, with soil carbon accounting for 44.798 metric tonnes and plant carbon accounting for only 3.828 metric tonnes per year. Despite these small amounts of plant carbon, the banana cropping system enriches the soil by enabling much more carbon to be sequestered into the soil in amounts comparable to other perennial plantations.
