【摘要】 通过60种化合物的增糖筛选,发现甜菜增糖剂2号(AP)——芳香羧酸类化合物,是一种优良的甜菜增糖剂。1984—1986年内,进行了多点、大面积田间试验,试验总面积达二千多亩。结果表明:在亩用有效剂量50—60g下,8月下旬喷药,通常可使甜菜块根增产7—17％,平均9.34％;提高甜菜块根含糖率0.4—2.5％,大部分提高0.6—1.4％;产糖量增加11—33％,平均20.2％;亩增产蔗糖平均为56kg。更多还原

【Abstract】 Sixty chemicals were studied to select the effective chemicals to increase the sugar content of sugarbeet.It was discovered that the sugar-in-crease-agent Ⅱ-aromatic carboxylic acid compound-was an excellent sugar-increase-agent. The field experiment was carried out in many regions and large area from 1984 to 1986. The total area was more than 2000 mu. The results showed that when sprayed with the effective dosage of 50-60g/mu in late August, it could usually increase the root yield by 7-17 %, average 9.34%; sugar content by 0.4-2.5% (most of which were between 0.6-1.4%) ; sugar production by 11-33%, average 20.2%. The average sugar production per mu was increased by 56Kg.更多还原
