| 摘 要： | 从表面看,影响甘蔗株高生长的气象因子有当旬的平均气温、蒸发量、降雨日数和平均风速。通径分析表明,平均气温是主要的影响因子,其它气象因子大多通过平均气温对株高生长起作用。逐步回归结果进一步印证了影响甘蔗株高生长的主要气象因子是平均气温。旬均温在25.0℃以下时,株高生长缓慢;旬均温为26.0-27.9℃时,株高生长速度最快。

Path analysis of climatic factors on sugarcane height growth |
| |
| Abstract: | This paper discusses 7 climatic factors that affect sugarcane height growth. Simple correlation analysis indicated that 4 factors, including average air temperature, the quantum of evaporation, the days of rainfall and the average speed of wind, had remarkable correlation with sugarcane height growth. However, path analysis indicated that only the average air temperature was the key climatic factor to sugarcane height growth. The other 6 factors mostly indirectly affected sugarcane height growth through air temperature. The result of stepwise confirmed that average air temperature was the main climatic factor affecting sugarcane height growth. Sugarcane growed slowly when the average air temperature of 10 days was lower than 25.0 ℃. The average air temperature of 10 days between 26.0-27.9 ℃ mostly adapted to sugarcane growth. |
