摘要:
低平易涝地耕层土壤水分大、土质粘重冷浆、通气透水性差、释放养分能力低等不良理化性状,是障碍大豆高产稳产的主要因素。大豆三深带状耕作栽培模式,是以机械化深松旋耕整地和带状栽培相结合的技术体系,改变了生产上翻、耙、压的耕作方式,较好地解决了低平易涝地土体构造不良状况和大豆的合理群体结构。试验结果表明,三深带状耕作栽培模式提高耕层土壤温度0. 8℃ ,降低土壤容重0. 1 98g /cm3 , 减少土壤含水量1 0. 1% , 分别提高速效氮、磷、钾19. 2% 、58. 9% 、36. 7% , 非毛管孔隙与毛管孔隙之比由1∶ 3. 15改善为1∶1. 66; 大豆叶面积指数增加32. 3% ,并表现出指数增长期较短、很快进入直线增长期、稳定期较长和衰亡期较短的良好发育动态。大豆籽粒产量三年平均增产15. 1% ,增产幅度为13. 7～ 16. 0% 。
