摘要
为了研究甘蔗各层土壤水分对甘蔗茎伸长量的影响,利用2009-2011年柳州市农业气象试验站甘蔗生育状况观测数据及同期的0～50cm各层土壤水分数据（土壤重量含水量、土壤相对湿度、水分总贮存量和有效水分贮存量）,利用Excel软件对甘蔗蔗茎旬伸长量与0～50cm各层土壤水数据进行统计回归分析.结果表明：2009-2011年旬甘蔗伸长量与20～30cm土壤水分关系最密切,呈极显著正相关,其次是30～40cm土层、10～20cm土层、0～10cm土层和40～50cm土层.有效水分存量与甘蔗生长关系最密切,其具有很好的指标作用.
The sugarcane data and the corresponding soil moisture data including soil water content, relative humidity, the total water storage and effective water storage from the Liuzhou agro-meteorological experiment station from 2009 to 2011 were used to study the impact of soil moisture in 0-50 cm soil layer on sugarcane stem elongation by statistical regression analyses of Excel software. The results showed that sugarcane stem elongation and soil moisture in 20-30 cm soil layer was most closely, showing a assume significant positive correlation, and followed by 30-40 and 10-20 cm soil layer, lastly 0-10 and 40-50 cm soil layer from 2009 to 2011. Effective moisture content and sugarcane growth was most closely related with a good indicator of the role.
