Abstract:

通过田间试验,研究了种植模式(大豆单作、玉米-大豆套作)和施氮水平(0,180,240kg.hm2)对大豆根瘤固氮特性和氮素吸收利用的影响。结果表明:随生育时期的推移,大豆的单株根瘤数、根瘤干重在单作模式下呈先增加再降低的趋势,而套作模式下则呈持续增加的趋势,在R5期最高;单株根瘤固氮潜力在两种种植模式下均呈先增加再降低的趋势,在R2期最高。与单作比较,套作大豆的单株根瘤数、根瘤干重、根瘤固氮潜力和总吸氮量在V5、R2期降低,在R5期则提高,氮素收获指数、氮肥农学利用率和吸收利用率显著提高。适量施氮有利于提高大豆的根瘤固氮能力,增加植株对氮素的吸收利用。套作模式下,减量施氮处理R5期的单株根瘤数、根瘤干重、根瘤固氮潜力及R8期的总吸氮量比不施氮处理高26.9%、15.5%、14.3%和58.2%,比习惯施氮处理高19.7%、12.0%、23.1%和11.3%,氮肥农学利用率和吸收利用率比习惯施氮处理高73.5%和20.1%。玉米-大豆套作减量一体化施肥促进了大豆根瘤固氮,提高了套作大豆和整个玉米-大豆套作系统的氮肥吸收利用效率。
