摘要
为研究蒜种种植方位对大蒜生长发育及产量的影响,为大蒜机械化种植装备的研发应用及其直立种植性能指标的确定提供依据,以杂交红蒜为试验对象,对蒜种种植方位进行单因素田间完全随机区组试验研究。结果表明:芽尖向上30°以上种植的大蒜在蒜薹长度和蒜头产量与水平种植差异不显著,但出苗早,出苗齐整,植株高大,建议芽尖向上30°以上作为衡量大蒜种植机械直立种植的指标。芽尖向下种植的大蒜出苗晚,出苗不齐整,与水平种植相比,出苗率低4%,蒜薹长度短6.9%~15.2%,蒜头产量减产8.4%~15.1%,蒜头的横径较小,大小不一致,形状不规则,立直种植时应尽量避免芽尖向下种植。
In order to study the effect of garlic planting position on garlic growth and yield and to provide the basis for the development and application of garlic mechanized planting equipment and the index of upright planting performance,hybrid garlic was planted with single factor complete randomized block design.The results showed that the garlic planted with bud tip up above 30°did not differ significantly from the garlic planted horizontal in the length of garlic stem and garlic yield,but it emerged early,the seedlings emerged neatly,the emergence rate was high,the plants were taller.It is suitable to use bud tip above 30°as an indicator to measure the upright planting of garlic planting machinery.Garlic planted with bud tip down emerged late and unevenly.Compared with garlic planted with bud tip horizontal,the emergence rate is 4%lower,the length of garlic stem is 6.9%~15.2%shorter,the yield of garlic is reduced by 8.4%~15.1%,and the transverse diameter of garlic is smaller and its shape is inconsonant and irregular.When upright planting,try to avoid planting with bud tip down.
