Research progress on regularity of nutrient activation and phosphorus nutrition in macadamia rhizosphere soil
China has become the country with the largest planting area of macadamia in the world.But the lack of understanding the plant nutrition regularity of macadamia limited the high yield and quality production of macadamia in China.In this paper,the nutrition distribution of macadamia was reviewed,and the formation of cluster root induced by low phosphorus and the rhizosphere nutrient activation were analyzed.The strategies for nutrient management were proposed including partial fertilization control,control of the total amount of nu-trient application and optimization of the ratio of nutrient forms,in order to optimize the rhizosphere environ-ment of macadamia,promote cluster root development and citric acid anion secretion,strengthen rhizosphere effect and root-fertilizer mutual feed synergistic effect,and improve the yield and quality of macadamia.Estab-lishment of systematic diagnostic criteria and verification of the appropriate phosphorus supply level in the fields will be key to achieve accurate nutrient management of macadamia,and will also be the focus of future research.
