根据内蒙古自治区甜菜产区的土壤条件和甜菜需肥规律研制的“中华1号”微肥,经1989年多点试验及大田示范表明该肥料有较好的增产增糖效果,并初步确定2.5kg/亩用量为经济施用量,在甜菜上随种施入,平均块根产量比对照增产194.6～352.0kg/亩,含糖率提高0.52～0.82％,平均每亩综合经济效益达60.91～102.25元。
According to the soil conditions in beet producing area of Inner Mongolia Autonomous Region and beet fertilizer requirement, “Zhonghua No.1” micro-fertilizer was developed. The multi-point test in 1989 and demonstration in Daejeon showed that the fertilizer has a good effect of increasing production and increasing sugar content. The initial 2.5kg The yield per mu was economic application. The average tuber yield increased 194.6 ~ 352.0kg / mu and the sugar content increased by 0.52 ~ 0.82% compared with the control. The average economic benefit per mu reached 60.91 ~ 102.25 yuan.
