【摘要】 本文通过测定不同失水时间的红松苗木的相对电导率,分析相对电导率与红松苗木活力的关系,发现红松苗木活力与水分下降、电解质外渗有密切相关,因此,通过测定苗木相对电导率可预测苗木的活力。更多还原

【Abstract】 Through determining ralative conductivity of Pinus koraiensis seedlings, the relation between seedling vigor and relative conductivity was studied in this paper. The result shows that seedling vigor is closely related to water descending and electrolyte exosmosis, and seedling vigor could be forecasted by relative conductivity.更多还原
