油茶是我国特有的木本油料树种,主要分布在华中、华南14个省(区)。长期以来发展不快,单产低,迄今平均亩产茶油仅3.4公斤。油茶低产的重要原因之一是授粉率低。它属于自花不孕树种,必须由昆虫传播、异花授粉,才能座果。造成授粉率低的关键问题有两点:1.油茶在“立冬”、“小雪”期间(公历十一月份)盛花。这时气温低,野生传粉昆虫数量少,活动能力弱。只靠自然授粉,其授粉率 Camellia oleifera is a unique woody oil species in our country, mainly distributed in central China and southern China 14 provinces (districts). For a long time, its unpleasant development and low yield have so far only averaged 3.4 kilograms of tea oil per mu. One of the important reasons for the low yield of Camellia oleifera is the low pollination rate. It belongs to self-infertile tree species, must be spread by insects, cross-pollination, in order to fruit. There are two key problems that cause low pollination rate: 1. Camellia flowers bloom during the “winter” and “light snow” (in the Gregorian calendar). At this time the temperature is low, a small number of wild pollinators, activity is weak. Only natural pollination, its pollination rate
