摘要：

利用柳州市沙塘国家农业气象试验站一级站2010—2012年甘蔗生长发育观测资料与主要的气象因子,重点分析了新植蔗、第一年宿根蔗和第二年宿根蔗旬伸长量与旬降水量、旬平均温度、旬平均日照时数的关系,并对甘蔗旬伸长量与气象因子进行相关分析。结果表明：甘蔗伸长量与旬降水量有较好的对应关系,该旬降雨量大,甘蔗旬伸长量就高,与当地降水规律重合,通过相关性分析,气象中的水分因子,降水量、相对湿度、旬平均水汽压与新植蔗、第一年宿根蔗和第二年宿根蔗旬伸长量呈显著或者极显著的正相关关系;旬平均温度与新植蔗旬伸长量呈正相关关系,但是不显著,与第一年宿根蔗和第二年宿根蔗旬伸长量呈显著的正相关关系;旬平均日照时数峰值对应旬伸长量低值,通过相关性分析旬平均日照时数与新植蔗、第一年宿根蔗和第二年宿根蔗相关性不显著,说明水分因子是决定甘蔗高度的关键气象因子。

Abstract:

Based on the growth and development observation data and main meteorological factors of sugarcane at the Shatang National Agricultural Meteorological Experimental Station in Liuzhou City from 2010 to 2012, the relationship between ten-day elongation of newly planted sugarcane, first-year ratoon sugarcane and second-year ratoon sugarcane and ten-day precipitation, ten-day average temperature and ten-day average sunshine hours was analyzed, and the correlation between ten-day elongation of sugarcane and meteorological factors was studied. The results showed that there was a good corresponding relationship between sugarcane elongation and ten-day precipitation. The ten-day elongation of sugarcane was high when the ten-day precipitation was large, which was consistent with the local precipitation law. Through correlation analysis, the meteorological water factor, precipitation, relative humidity and ten-day average water vapor pressure were significantly or very significantly positively correlated with the ten-day elongation of new planting sugarcane, first-year ratoon sugarcane and second-year ratoon sugarcane. There was a positive correlation between ten-day average temperature and ten-day elongation of newly planted sugarcane, but it was not significant. There was a significantly positive correlation between ten-day average temperature and ten-day elongation of the first year and the second year. The peak value of ten-day average sunshine hours corresponded to the low value of ten-day elongation. Through correlation analysis, the correlation between ten-day average sunshine hours and new planting sugarcane, first-year perennial sugarcane and second-year perennial sugarcane was not significant, indicating that water factor was the key meteorological factor to determine sugarcane height.

Key words: sugarcane, production cycle, elongation, meteorological factors, precipitation, correlation analysis
