摘要
为了实现谷子中耕机械化,提高工作效率,结合农艺与农机,把传统的33 cm等行距种植模式改为50 cm/16.6 cm适应机械中耕的宽/窄行种植模式。试验结果表明,产量、株高、穗长、穗质量、功能叶面积等性状在宽窄行和等行距不同种植模式之间差异不显著,而在中耕与不中耕处理之间差异显著或极显著。50 cm/16.6 cm的宽/窄行既不会影响产量,而且又适应机械中耕,是理想的种植模式。
To realize mechanized intertillage in millet fields and improve work efficiency,wide/narrow row space of 50 cm/ 16.6 cm combined with agricultural technology and machinery substituded for the traditional planting mode of the 33cm equal row space.The results showed that in yield,plant height,spike length and weight,and functional leaf area there were no significant difference between the equal rows mode and wide/narrow row method.But there were significant differences between the lands with intertillage and without intertilled.The 50 cm/16.6 cm mode was not only helpful to increase production but also adaptable to mechannical intertillage,which is an ideal choice for the mechanized intertillage.
