| 摘 要： | 以湖南省１３年的气象资料，按银杏果生长发育周期，分５个阶段统计了水、光、热诸方面的８个气象因子，采用多元逐步回归方法，筛选出传粉受精期平均最大风速、种实第二增长高峰期的最低气温和５月１日～６月３０日的总雨量３个对产量有重要影响的气象因子。相应时期较大的风速，较低的气温、充沛的雨量，可提高银杏产量。 |
| 关 键 词： | 银杏 气象因子 产量 相关性 |

| Abstract: | he effectof eight meteorological factors such as the precipitation,sunshine hours,and air temperatureon the ginkgo plant (Ginkgo biloba)in terms of fruit growth and nut yield in five differentdevelopmental phases was studied. The multivariate stepwise regression analysis indicatedthat the three factors influenced the nut yield at the significance level,namely,the maximummean windvelocity during the phase of pollination,the mean lowest air temperature duringthe second peak phase of fruit growth,and the total rainfall from May 1 to June 30. It isargued that a great wind velocity,a low air temperature,and an abundant precipitation ateach of these growth phases respectively are favorable for the fruit growth and hence a goodand high nut yield can be expected. |
