Zusammenfassung:	The invention discloses a preparation method and application of an algae hydrothermal carbon material. The preparation method comprises the following steps: mixing algae and a reaction medium according to a solid-liquid ratio of 50-100g/L, fully stirring, reacting for 3-5 hours under self-generated pressure and at the temperature of 130-150 DEG C, and after the reaction is completed, carrying out suction filtration separation, washing, drying and grinding to obtain the algae hydrothermal carbon material, the reaction medium is a mixed solution of ammonium phosphate and ammonia water. The prepared algae hydrothermal carbon material can be used for improving the physicochemical properties of saline-alkali soil, reducing the pH value and the salt content, and achieving the purpose of increasing the crop yield. 本发明公开了一种藻类水热炭材料的制备方法和应用。将藻体与反应介质按照固液比例为50~100 g/L进行混合，充分搅拌后，在自生压力和130~150℃的温度下反应3~5 h，反应完成后进行抽滤分离、洗涤、干燥以及研磨，得到藻类水热炭材料；所述反应介质为磷酸铵和氨水的混合溶液。所制备的藻类水热炭材料可应用于改善盐碱地理化性质，降低pH和含盐量，实现提高作物产量的目的。
