甜菜为我县经济作物之一,近年来发展很快,但栽培水平不高,单位面积产量和含糖量很低,并有逐年下降趋势。海伦县三十年来甜菜产量始终徘徊在一吨左右,每年只是增加种植面积来保证制糖工业发展的要求,而含糖率却从60年代的平均17—18％下降到70年代的15—16％,近两年平均只有14—15％。为使我县甜菜生产水平尽快搞上去,1982年开始应用综合栽培方法,摸索出提高产量和含糖率的一些途径,现综述如下:
Beet is one of the cash crops in our county, developed rapidly in recent years, but the cultivation level is not high, yield per unit area and sugar content is very low, and there is a downward trend year by year. Helen County beet production has been hovering around a ton in 30 years, only increasing the acreage every year to ensure the development of the sugar industry, while the sugar content dropped from an average of 17-18% in the 1960s to 15-16 in the 1970s %, An average of only 14-15% in the past two years. To make my county beet production as soon as possible to go up, began in 1982 the application of integrated cultivation methods, to explore some ways to increase production and sugar content, are summarized as follows:
