植物营养学在经济林研究中的运用

摘要

Plant nutrition is a subject studying the laws of absorption, transportation, translation and utilization, as well as interchange of nutrient substances and energy between plants and external environment, and it was used widely in agriculture and forestry production. On the base of research progress of plant nutrition, its applications in non-wood forest variety breeding, nutrition diagnosis, fertilization and stress tolerance were introduced in the article , and research directions of non-wood forest nutrition was discussed, rrelationships of mineral elements in the soil or soilless solution their role in plant growth,.%植物营养学是研究植物对营养物质的吸收、运输、转化和利用规律及植物与外界环境之间营养物质和能量交换的学科,在农林生产中运用广泛.文中结合植物营养学科的研究概况及趋势,简要介绍其在经济林品种选育、营养诊断与施肥、树体调控及抗逆研究中的运用,并对今后经济林营养学的研究方向进行了探讨.
