龙溪地区地处北纬23.6～25℃,大部分地段属南亚热带农业气候区。气候温和,年平均气温21℃,雨量充沛,年总雨量1100～2000毫米,适宜荔枝生产。但荔枝开花对气候条件反应很敏感,冬暖多雨年份,有利冬梢抽长,影响花芽的形成;春季由于冷暖气流锋面交错,气候多变,尤其是4月份荔枝盛花期,常遇到春雨绵绵,或北方冷气流的袭击,突然降温,严重地影响授粉和座果。本文将在“论荔枝丰歉与气候的关系”一文的基础上,从花粉萌发
Longxi area is located at latitude 23.6 ~ 25 ℃, most of the area is a subtropical agricultural climate zone. A mild climate, the annual average temperature of 21 ℃, abundant rainfall, annual rainfall of 1100 ~ 2000 mm, suitable for litchi production. However, lychee flowering is very sensitive to climatic conditions, the winter warm and rainy years, conducive to the winter shoot long, affecting the formation of flower buds; spring due to cold and warm air front staggered, climate change, especially in April flowering litchi, often encounter spring rain , Or the northern cold air flow attacks, a sudden cooling, seriously affecting pollination and fruit. Based on the article "On the relationship between climate change and climate change in litchi,
