荔枝是当前国内外市场供不应求的名贵果品之一。生产上由于存在“花多实少”,产量低而不稳,严重限制了荔枝生产的迅速发展。原因很多,主要是长期管理粗放,施肥不足,特别是春季花期气候多变,低温、阴雨、干风,不利蜜蜂传粉。采用人工授粉,可以大大提高着果。田间收集花粉费工费时,短期内又无法满足大面积果园特别是边远地区需要。为此,作者于1981～1984年对利用蜜蜂花粉团进行室内发芽及室外荔枝人工授粉试验。现将初步结果分述如下:
Lychee is currently one of the most expensive fruits in short supply at home and abroad. Production due to the existence of “spend more and more less,” low yield and instability, severely limited the rapid development of litchi production. There are many reasons, mainly long-term management of extensive, inadequate fertilization, especially the spring flowering climate change, low temperature, rainy, dry wind, adverse bee pollination. Using artificial pollination, can greatly enhance the fruit. Fieldwork to collect pollen time-consuming, short-term and can not meet the needs of large areas especially in remote orchards. To this end, the author in 1981 to 1984 on the use of bee pollen group for indoor germination and artificial litchi outdoor artificial test. Now the preliminary results are as follows:
