| 摘 要： | 在通辽地区以田间4种密度条件下研究了甜菜株高、根粗、鲜重冠根比等生理性状的变化及其与块根产量、舍糖率、产糖量的关系。结果表明，甜菜株高、鲜重冠根比随着种植密度的增加而增加；根粗、块根鲜重、叶鲜重随着种植密度的增加而降低。在产量、含糖率、产糖量上都表现出：B3处理〉B2处理〉B1处理〉B4处理。综合评析得出B3处理（即9．0万株／hm^2）为最适密度处理。

| Abstract: | Four experiment at treatments were conducted to research density effect on plant height, root thick, crown root ratio of fresh weight, root yield and sugar content of sugrabeet. The results showed that plant height and crown root ratio of fresh weight gradually increased with increasement of planting density; meanwhile root thick, weight of root and leaf decreased with increasement of planting density. The root yield, sugar content and sugar yield were treatment B3〉B2〉B1〉B4. The optimum density was B3 treatment （90000 plants per hectare） in Tongliao area. |
