| 中文摘要:茶树生长在很大程度上受外界环境条件影响，不同气象因子对茶叶生产的影响程度也不一样，为找到影响茶叶产量的主要因素，便于在实际生产中应对外界环境变化对茶叶生产带来的影响。以陕南8个主要产茶县（区）2007-2016年的气象因子和茶叶产量为对象，运用灰色关联分析法研究陕南茶区气象因子与茶叶产量的关联度。结果表明：年平均相对湿度、极端最高气温和平均气温是影响陕南茶区茶叶产量的主要因素。研究结果可为陕南地区茶树气候适宜性区划和扩张种植提供依据。 |

| Abstract:The growth of tea plant is affected by environment conditions to a great extent,but the effects of different meteorological factors on tea production is different.Meteorological factors and tea yield as targets in 8 main tea-producing area in southern Shaanxi during 2007 to 2016 were studied.The grey correalation was used to study the relationship between meteorological factors and tea yield.The results showed that annual average relative humidity,extreme maximum temperature and average temperature were the main factors affecting tea yield in Southern Shaanxi. |
