大面积的产量低且不稳是油茶生产上长期存在的突出问题。油茶低产主要表现为落花、落果严重、花而不实。因此,从五十年代以来不少科研单位就着手从加强水肥管理和防治病虫害等方面进行保花、保果的研究,但总的说来收效不大。六十年代以来,中国林科院亚林站等单位开始注意油茶开花的生物学和生态学的研究,试图从开花习性来探索油茶的结实规律和低产原因,无疑这个研究方向是正确的。这是因为油茶为秋、冬开花且为 A large area of ​​low yield and instability is a prominent problem in the long-standing production of Camellia oleifera. The main yield of Camellia low-flowering, fruit drop serious, but not real flowers. Therefore, since the 1950s, many scientific research institutes have started to study the protection of flowers and fruits from the perspectives of strengthening the management of water and fertilizer and preventing pests and diseases, but in general they have not achieved much success. Since the 1960s, the Chinese Academy of Forestry Yalin Station and other units began to pay attention to the biology and ecology of flowering Camellia oil, trying to explore from the flowering habits of Camellia strong law and low yield, no doubt this research direction is correct. This is because the tea is autumn and winter flowering and for
