LEACHING FRACTION AND FERTILIZATION EFFECTS ON GROWTH OF THREE WOODY LEGUMES INOCULATED WITH RHIZOBIA

摘要

Scotch laburnum [Laburnum alpinum (Mill.) Bercht.], Amur maackia (Maackia amurensis Rupr, and Maxim.), and Chinese wisteria [Wisteria sinensis (Sims) Sweet] were inoculated with compatible rhizobia and treated with leaching fractions (LF) of 0, 0.2, and 0.4 using fertilizer solutions with 3.6 and 10.7 mol N/m(3) for 10 weeks, LF did not affect plant dry mass, leaf area, or stem length, Growth was higher among plants provided 10.7 mol N/m(3), but only plants provided 3.6 mol N/m(3) formed root nodules, We conclude that growth is not reduced by eliminating leaching during the first 10 weeks of seedling development, and that application of 10.7 mol N/m(3) prevents nodulation of these species.
