本文以相关分析和方差分析,研究闽中闽南蔗区甘蔗蔗糖份和成熟期间自然气象要素的关系。认定甘蔗工艺成熟的九、十月份,是由茎叶伸长生长为主,转入蔗糖份积累为主、关键性的生理转析时期。在自然情况下,对蔗糖份积累起限制性作用的气象要素,是日照时数和雨量。81/82年榨季,闽中(仙游)、闽南(泉州、漳州、厦门、云霄)五个糖厂蔗区的全榨季平均甘蔗蔗糖份的降低,和工艺成熟期间发生自然气象要素的异常程度相一致。确认蔗糖份下降,起主导作用的,是气象要素的异常。本文还提出五个糖厂蔗区的全榨季平均甘蔗蔗糖份的正常变化范围,以供查明正常与异常年份之参考。
In this paper, correlation analysis and analysis of variance were used to study the relationship between sucrose content of sugarcane in sugarcane field and natural meteorological factors in Fujian and Fujian Province during its maturity. Accreditation of sugar cane technology maturity in September and October, stems and leaves from the growth of the main growth, transferred to the accumulation of sucrose-based, the key physiological period of the transfer. In natural conditions, the meteorological elements that have a limiting effect on the accumulation of sucrose are the hours of sunshine and rainfall. During the 81/82 cropping season, the average sugar cane sugar content of the five sugarcane plantations in Minzhong (Xianyou) and Minnan (Quanzhou, Zhangzhou, Xiamen and Yunxiao) was reduced and the natural meteorological elements Abnormal level consistent. Confirm the decline of sucrose, play a leading role, is the abnormal weather elements. This paper also proposed that the average sugar cane sugar content of all sugar cane sugarcane fields during the whole cropping season should be used as a reference for the identification of normal and abnormal years.
