Abstract:

通过大田圆柱管栽培试验,研究生物炭与氮肥的交互作用对大豆生长发育及产量的影响。结果表明:适量施入生物炭对单株干物质积累与LAI的调控起到了促进作用,其调控作用在生育后期大于生育前期。在R6期C1(施炭750kg?hm-2)处理单株干物重与LAI最高,但随着施炭量的进一步增加单株干物重与LAI却逐渐下降,施炭量为C3(施炭2250kg?hm-2)时单株干物重与LAI低于不施炭处理。施入生物炭使大豆株高降低,施炭量越多株高降低幅度越大。在相同施炭量条件下,不同施氮处理各生育时期单株干物重及叶面积指数的均值以N2(施氮60kg?hm-2)最高,叶绿素的均值以N3(施氮90kg?hm-2)最高。施炭750kg?hm-2和施氮42kg?hm-2为大豆高产的最优施用组合,理论产量为3546.9kg?hm-2。生物炭与氮肥配合施用,主要是通过调节单株粒数来影响产量。
