前言 根系是树木的重要营养器官,它的功能主要是吸收土壤中的水分和溶于水中的无机盐类,并参予许多有机化合物的合成。因此,根系与树木的生活和生长发育有着极为密切的关系。 然而,由于已知的根系研究法都相当繁锁,费时费力,且所得结果又常常不太准确,所以,严重影响着研究根系的积极性,尤其对在野外自然条件下研究林木根系的工 Introduction Root system is an important vegetative organ of trees, its function is mainly to absorb soil moisture and inorganic salts dissolved in water, and participate in the synthesis of many organic compounds. Therefore, the root system and tree life and growth and development have a very close relationship. However, since the known root research methods are quite cumbersome, time-consuming and laborious, and often infrequently-obtained results, they severely affect the enthusiasm of studying the root system, especially for the study of tree roots under natural conditions in the wild
