原料甜菜主要有两大经济指标:一是块根产量,二是工艺品质。黑龙江省近几年来,甜菜糖份高低波动很大,其原因是多方面的,如品种,栽培方法,病虫害,叶片损伤及气象因子等。气象因子除外的其他方面,从整体来看变动性不太大,所以对甜菜的含糖高低的影响也不太大,而气象条件这几年变动确实相当大,所以,甜菜含糖大幅波动,主要是气象条件的变动所起的。故对气象主要因子——降雨、日照、有效积温等对甜菜含糖的影响进行分析。
There are two major economic indicators of sugar beet raw materials: First, root yield, and second, process quality. In recent years, the content of sugar in beet has fluctuated greatly in Heilongjiang Province for many reasons, such as varieties, cultivation methods, pests and diseases, leaf damage and meteorological factors. Other factors except meteorological factors, the overall change is not too large, so the sugar content of sugar beet is not too much influence, but the weather conditions in recent years changes are indeed quite large, so beet sugar swings, Mainly due to changes in weather conditions. Therefore, the main factors of meteorology - rainfall, sunshine, effective accumulated temperature on the sugar content of sugar beet were analyzed.
