不同种类有机物料腐解过程及养分释放特征
Decomposition Process and Nutrient Release Characteristics of Different Types of Organic Materials
摘要
Abstract
This study aimed to enhance the utilization of agricultural organic residues,specifically crop straws and animal manures,by employing a nylon mesh bag burial method in conjunction with a first-order kinetic model.The research focused on the decomposi-tion patterns and nutrient release characteristics of three key organic materials,i.e.,the wheat straw,cow manure,and chicken ma-nure.Results indicated that the decomposition processes of these materials were characterized by distinct phases,with an initial rap-id phase followed by a slower phase.After 177 days of burial,the cumulative decomposition rates for wheat straw,cow manure,and chicken manure were 46.1%,29.4%,and 13.1%,respectively.The first-order kinetic model predicted a potential decomposition rate of 73.1%for wheat straw.The cumulative release rates of carbon,nitrogen,phosphorus,and potassium from the three organic materials ranged from 37.9%to 68.2%,54.2%to 74.0%,52.3%to 86.4%,and 68.9%to 91.3%,respectively,with the order of K>P>N>C.The wheat straw showed higher cumulative decomposition and nutrient release rates compared to the cow and chicken ma-nures.The rapid release of phosphorus and potassium suggested that incorporating these organic materials into the soil could quickly enhance soil phosphorus and potassium availability.The study also highlighted that the decomposition rates and nutrient release rates of organic materials were influenced by various factors,including the physical structure and chemical composition of the organic ma-terials,as well as soil environmental conditions.These factors collectively shape the decomposition behavior and nutrient release pat-tern of organic materials in the soil.To optimize the use of organic materials and improve soil fertility,it is essential to consider these factors and develop appropriate strategies for the return of organic materials to the soil.关键词
