| 摘 要： | 为探求适合黄淮海平原机播夏玉米的最佳麦茬处理方式,于2005年、2006年采用大田试验,研究了麦茬处理方式(平茬、立茬、除茬)对机播夏玉米播种质量及其前期生长的影响。结果表明,除茬在播种深度、播深整齐度和出苗穴距均匀度方面表现较好,播种质量较高,但处理间没有显著性差异;三展叶时,玉米叶绿素含量、单株干物质重等指标都以除茬处理最好;六展叶时,平茬处理玉米的株高、单株叶面积、单株干重、光合速率均表现最优。综合而言,平茬处理能满足机播夏玉米的播种要求,有利于夏玉米的前期生长。

| Abstract: | A field experiment was carried out to explore the effects of different treatments of winter wheat residues,including returning straw(RS),high stubble (20cm high) with mulched(HS) and zero stubble (ZS),on planting quality and early-stage growth of mechanical sowing summer maize(Zea mays L.) in 2005 and 2006.The results showed that the sowing depth,the uniformity of sowing depth and the evenness of emergence point distance for ZS were better than other treatments,but there was no significant difference among ... |
