甘蔗糖分的高低,不仅与品种、植期、土壤质地、密植程度、施肥管理有密切关系,而且与气候因素和榨期也息息相关。太平、信都、蒙山三间糖厂,地处三个不同的纬度,太平处在北纬23°39′,信都处在北纬23°58′,蒙山处在北纬24°12′。不论所处纬度高低,1981/82年榨季糖分都普遍降低,比1978/79年至1980/81年三个榨季中任何一个榨季都偏低,平均偏低0.62％,比糖分最佳期的12—3月份同期平均降低0.7％(见表一)。 Sugarcane sugar level, not only with the variety, planting, soil texture, density, fertilization management are closely related, but also with the climatic factors and squeezing period are also closely related. Taiping, Xindu and Mengshan are located at three different latitudes, at a latitude of 23 ° 39 ’north latitude, at 23 ° 58’ north latitude and at Mengshan at latitude 24 ° 12 ’north. Regardless of the latitude, the 1981/82 crop sugar generally declined, compared with any one of the three crop seasons from 1978/79 to 1980/81, the crop seasons were low with an average of 0.62% lower than the best sugars During the same period in December-March, the average decrease of 0.7% (Table 1).
