The present invention provides a gene for identifying Ralstonia solanacearum of Casuarina equisetifolia and a specific detection method. The present invention uses bioinformatics technology to analyze the DNA of Ralstonia solanacearum of Casuarina equisetifolia in western Guangdong, and through pan-genome alignment analysis and research with other bacteria and Ralstonia solanacearum of other hosts, a specific gene sequence that can be stably inherited by Ralstonia solanacearum of Casuarina equisetifolia is obtained, as shown in SEQ ID NO.1. Taking this gene as a target can specifically detect and identify Ralstonia solanacearum of Casuarina equisetifolia and specifically monitor Ralstonia solanacearum wilt of Casuarina equisetifolia. The present invention also optimally designs specific detection primers and kits, which have the advantages of strong specificity, high accuracy, good repeatability, high sensitivity, etc., and are simple, rapid to operate, can be applied to the rapid detection of Ralstonia solanacearum of Casuarina equisetifolia, have good applicability, and have important application value and significance for the prevention and control of Ralstonia solanacearum wilt of Casuarina equisetifolia.

This invention discloses a method for producing porous biomass carbon using Casuarina equisetifolia. The method involves reactively extruding Casuarina equisetifolia powder, ammonium polyphosphate, melamine, potassium acetate, urea, and water using a twin-screw extruder to obtain a rheological phase plasticizing precursor. This precursor is then refined through segmented curing and foaming, high-temperature reforming activation, hot water digestion, and ultrasonic acid washing to obtain porous biomass carbon. This invention utilizes a eutectic system to achieve low-temperature continuous processing of the precursor and inhibits equipment corrosion. A well-developed pore structure is constructed through a stepwise cross-linking foaming and mild activation strategy. The porous biomass carbon prepared by this invention has an ash content ≤1.12%, a carbon yield ≥35.7%, an iodine adsorption value ≥1278 mg / g, and a methylene blue adsorption value ≥175 mg / g. Furthermore, the process is continuous, with minimal equipment corrosion, making it suitable for industrial production.
