    摘要:

    为了探明不同耕层构造对玉米生长发育及产量的影响,通过人工模拟方式构造不同类型耕层。研究结果表明:留茬苗紧行松叶面积比垄作苗紧行松提高4.19%;苗紧行松耕作提高玉米干物质积累速率,相比之下平均每天每平方米干物质量积累幅度为0.69~3.96 g;苗紧行松分别比苗紧行紧和苗松行松耕作产量高20.06%和4.08%,苗紧行松与苗松行松产量差异达显著水平(P<0.05),而与苗紧行紧差异未达显著水平(P>0.05)。

    Abstract:

    In order to study effects of different tillage structures on growth and yield of maize, different types of tillage layer were constructed. The results showed that leaf area of maize under tillage of compact in rows and loose between rows with high stubble was 4.19% higher than tillage with ridge. Tillage of compact in rows and loose between rows promoted dry matter accumulation rate of maize, dry matters were accumulated from 0.69g to 3.96g per day per m2 with comparison of other tillage structures. Yield of tillage of compact in rows and loose between rows was 20.06% and 4.08% higher than tillage of compact in rows and between rows and tillage of loose in rows and between rows. Though the difference was significant between tillage of compact in rows and loose between rows and tillage of loose in rows and between rows, the difference was not significant between compact in rows and loose between rows and tillage of compact in rows and between rows.
