【摘要】 以山东釆种甜菜区一直釆用的甜菜制种栽培密度(行×株=60 cm×40 cm)为对照,在该区设行距均为60 cm,株距设5个处理(分别为30 cm、40 cm、50 cm、60 cm、70 cm)进行对比试验,以探寻与当地气候条件和栽培管理措施形成最优组合的最佳栽植密度。试验结果表明:该区一直采用行距为60 cm,株距为40 cm的栽植密度与当地的气候条件和栽培管理措施较为符合。更多还原

【Abstract】 Five different planting spaces(30 cm,40 cm,50 cm,60 cm,70 cm respectively) were applied with the same row space(60 cm) to explore the suitable planting density in the local climatic conditions and management measures.The row and plant space(60 cm×40 cm) as a control was considered as the suitable level of seed sugarbeet in Shandong province.The results showed that the widely used planting density(60 cm×40 cm) is suitable to the local condition.更多还原
