摘要: 采用盆栽模拟试验,通过豌豆与玉米间作,并对单作和间作豌豆进行根瘤菌接种,研究了接种对豌豆结瘤固氮特性、豌豆及间作玉米的氮素吸收量、作物生长状况的影响。结果表明,间作及接种提高了固氮酶的活性;相对于间作不接种,间作接种根瘤菌ACCC16101(R1)和XC3.1(R2)后,根瘤重量增加了19.0%~120.4%;ACCC16101对间作作物的氮素吸收量及干物质积累量影响较小;间作接种XC3.1后, 豌豆、玉米的氮素吸收量及干物质积累量显著增加,籽粒产量比间作不接种提高16.9%和19.1%,土地当量比也高于接种ACCC16101和不接种;XC3.1适宜在豌豆/玉米间作系统中接种。

Abstract: A Rhizobium inoculation experiment was conducted in a pea/maize intercropping system to investigate the changes of nodulation, nitrogen (N) fixation, N absorption, and crop growth. Nitrogenase activity of Rhizobium in pea nodules was increased significantly by intercropping and inoculation with ACCC16101 (R1) and XC3.1 (R2). Nodule weights of intercropped pea increased by 19.0%-120.4% after inoculation with these two Rhizobium strains. ACCC16101 had little effect on N absorption and dry matter accumulation of either pea or maize. In an intercropping system inoculated with XC3.1, N and dry matter accumulation of these two crops were considerably improved and seed yields of pea and maize increased by 16.9% and 19.1%, respectively. XC3.1 is suitable for inoculation in a pea/maize system.
