红阳猕猴桃种植基地自动站温度对其生长季的影响

Impact of base meteorological automatic station of temperature on Hongyang kiwifruit growing season

利用贵州西部发耳、米箩、猴场、蟠龙、鸡场、顺场、杨梅、勺米共8个红阳猕猴桃基地2013—2015年物候期观测资料、猴场基地红阳猕猴桃果实生长期生长速率及其产量资料以及各基地2005—2015年温度资料,运用C值逼近法和决定系数(R^2)最大化法拟合红阳猕猴桃果实生长曲线,采用相关性分析方法,分析了温度对红阳猕猴桃物候期的影响。结果表明,红阳猕猴桃各个物候期出现的时间及其日数与温度变化具有一致性,但各个物候期对温度的响应表现出不一致。红阳猕猴桃开花期对平均温度、平均最高温度的响应最为明显,其相关性达到极显著水平(p<0.001)。平均最高温度对果实生长期日数的影响呈负相关性,其相关性达到极显著水平(p<0.005)。果实生长量的75.69%受时间影响,24.31%受气候因素影响。

By using the phonological period observation data of eight Hongyang kiwifruit bases like Faer,Miluo,Houchang,Panlong,Jichang,Shunchang,Yangmei,Shaomi of western Guizhou during 2013—2015,Hongyang kiwifruit growth rate in growth period and yield data of the Houchang field base and the temperature data of each base during 2005—2015,the C value approximation method and the coefficient of determination（ R^2） growth curve fitting method were used to fit the Hongyang kiwifruit growth curve. By correlation analysis method,the influence of temperature on the phonological period of the Hongyang kiwifruit was analyzed. Results indicated that occurrence time and day of Hongyang kiwifruit in each phonological period is consistent with the temperature variation,but the responses to temperature in each phonological period are different. Hongyang kiwifruit in flowering period has the most obvious effects on the average temperature and the average maximum temperature,and its correlation reaches extremely significant level（ P〈0. 001）. The average maximum temperature has a negative correlation with the daysof fruit growth,and the correlation was very significant（ P〈0. 005）. 75.69% of the growth of the fruit was influenced by the time,and the 24. 31% was influenced by the climatic factors.
