我厂自1980年正式投产以来,甜菜含糖率时高时低,出现过五个含糖超过15％的高糖年份、六个含糖低于15％的低糖年份。特别是1991年,全市甜菜含糖只有12％。造成低糖的原因有三点:一是气象条件;二是病害;三是栽培条件。其中气象条件的影响是主要因素。 1 气象条件的影响气象条件主要指在糖分积累期的气温适宜与否、降雨量的多少、日照时效的多少、
Since the plant was officially put into operation in 1980, sugar beet has a high and low sugar content, five high sugar years with more than 15% sugars and six low sugar years with less than 15% sugars. Especially in 1991, the sugar beet only 12% in the city. Cause low sugar for three reasons: First, weather conditions; the second is disease; third is the cultivation conditions. The impact of weather conditions is the main factor. 1 Meteorological conditions Meteorological conditions mainly refers to the temperature during the accumulation of sugar appropriate or not, the amount of rainfall, sunshine duration,
