摘　　要：大兴安岭岭西地区机播甜菜设定行距50 cm和株距18 cm的条件下,田间实际株距分布不不均匀,总的趋势是株距小对应甜菜群体块根小、株距大对应甜菜群体块根大.秋翻大麦防风田、春翻大麦防风田、免耕田株距小于等于30 cm时,田间不同株距范围甜菜株数、面积、重量分布频率呈近似正态分布,而旱地甜菜则不符合这一规律,无论是秋翻大麦防风田、春翻大麦防风田、免耕田、旱田大于30 cm株距范围甜菜株数、面积、重量分布频率都比较高.秋翻大麦防风条件下,不同块根重量范围甜菜数量和重量分布频率峰值都在600 g-750 g重量范围内,甜菜块根数量分布和重量分布皆呈近似正态分布规律.甜菜群体平均单株块根重和株距的关系是直线关系,群体单株块根重与株距呈极显著正相关关系,第一条直线斜率大于第二条直线斜率,甜菜群体单产(kg/667 m^(2))和株距也是两条直线关系,第一条直线表示甜菜单产(kg/667 m^(2))与株距呈极显著正相关关系,第二条直线则表示甜菜单产(kg/667 m^(2))与株距呈显著负相关关系.Under the conditions of set row spacing of 50.0 cm and plant spacing of 18.0 cm for machine sown sugar beets in the western region of the Greater Khingan Mountains,the actual distribution of plant spacing in the field is uneven.The overall trend is that small plant spacing corresponds to small beet root in the sugar beet population,while large plant spacing coresponds to large beet root in the sugar beet population.When the plant spacing of barley windbreak field with soil turned up in autumn,barley windbreak field with soil turned up in spring,and no tillage field is less than or equal to 30.0 cm,the distribution frequency of the number,area,and weight of sugar beets in different plant spacing ranges in the field is approximately normal distribution,while that of sugar beets in dry land does not conform to this law.The distribution frequency of the number,area,and weight of sugar beets in barley windbreak field with soil turned up in autumn,barley windbreak field with soil turned up in spring,no tillage field,and dry land with plant spacing greater than 30.0 cm is relatively high.Under the condition of barley windbreak field with soil turned up in autumn,the peak value of sugarbeet number and weight distribution frequency in different beet root weight range was in the range of 600g-750g weight,and the distribution of sugarbeet root number and weight was similar to normal distribution.The relationship between the average root weight per plant and plant spacing in a sugar beet population is a linear relationship,with a highly significant positive correlation between the average root weight per plant and plant spacing.The slope of the first straight line is greater than the slope of the second straight line,and the yield(kg/667 m^(2))and plant spacing in a sugar beet population are also two linear relationships.The first straight line represents a highly significant positive correlation between the yield(kg/667 m^(2))of sugar beet and plant spacing,while the second straight line represents a significant negative co
