摘要
当前面临着两大世界级问题“土壤退化”和“双碳目标”,而这两大问题均有一个共通点——碳!那植物吸收碳元素途径有哪些呢?人类能否通过农作物及农事操作助力实现“双碳”目标?为深入了解这其中的关联性,为农业可持续发展和助力实现双碳目标,本文从上述2个问题出发,从碳元素生态系统循环切入思考。通过阅读大量文献,跟踪学术前沿,综述植物吸收碳源途径和富碳有机肥料的应用研究。结果发现植物吸收和利用碳元素代表性成果如下:(1)植物的营养物质包括有机质和矿物质。(2)完善了生态系统的碳循环途径:增加植物通过根系直接吸收利用小分子碳水化合物的途径,即生态系统碳循环中碳可以从土壤到植物。(3)富含碳元素的肥料主要包括腐植质、有机肥、微生物有机肥、有机碳肥等。依据植物吸收碳元素途径中植物可以通过根系吸收小分子有机碳,农民可以通过农事操作增加耕地土壤中有机质,改良土壤促进农作物生长的同时助力实现“碳达峰、碳中和”目标。
At present,we are faced with two world-class problems of“soil degradation”and“carbon peaking and carbon neutralization”target,both of which share a common point of carbon.What are the pathways for plants to absorb carbon?Can humans help achieve the goal of“carbon peaking and carbon neutralization”through crops and agricultural operations?To gain a deeper understanding of the interrelationships among them,and to contribute to the sustainable development of agriculture and the achievement of the“carbon peaking and carbon neutralization”target,this article started from the above two issues and the perspective of the carbon element ecosystem cycle.By reading a large amount of literature,tracking academic frontiers,summarizing the pathways of plant carbon absorption and the application research of carbon rich organic fertilizers,the representative results of carbon absorption and utilization by plants were found as followed.(1)Plant nutrients included organic matter and minerals.(2)The carbon cycle pathway of the ecosystem had been improved:increasing the way for plants to directly absorb and utilize small molecule carbohydrates through their roots.That is,in the carbon cycle of the ecosystem,carbon could be transferred from soil to plants.(3)Carbon rich fertilizers mainly included humus,organic fertilizer,microbial organic fertilizer,organic carbon fertilizer,etc.According to the pathway that plants absorb carbon elements,plants could absorb small molecule carbohydrates through their roots.Farmers could increase organic matter in cultivated soil through farming operations,improve soil and promote crop growth,while helping to achieve the goal of“carbon peaking and carbon neutralization”.
