摘要:
通过恒温腐解大豆根系所得到的腐解液处理大豆种子表明,腐解1个月的大豆根系腐解液可抑制大豆种子萌发生长, 抑制率为18% - 22% ,经4个或6个月腐解的大豆根系腐解液对大豆种子萌发的影响差异不显著,大豆根系表面水浸液对大豆种子萌发不产生显著影响。通过大豆根拌土盆栽试验表明: 大豆根系对下茬大豆生长有显著影响,正茬土拌大豆根系较不拌大豆根系的处理减产6% - 24% ,并且随着加入根系量的增多,减产幅度增加,大豆根系拌土腐解一年后再种植大豆,对产量和生育期各阶段生物量不产生影响。根系腐解液和大豆根系拌土盆栽试验证明了生产上大豆根对下茬大豆从种子萌发开始,就发生抑制,随时间的延长,抑制作用减弱,生产上约经两年左右,抑制作用彻底消失,由此表明了大豆根系腐解中间产物是大豆连作主要障碍之一。
