研究了ＵＦ１与ＵＦ２油茶调控剂对油茶年发育周期中营养循环和生殖循环的化学调控效果及其与产量形成的关系。结果表明：在油茶春梢生长到一定时期喷施ＵＦ１，可适度抑制其生长，但促进翌年抽梢数和结果枝的增加，观测枝单叶面积虽略有减小，但叶片数量和厚度却有所增加；在油茶开花盛期喷施ＵＦ２（２次），可明显提高座果率，降低落果率，使单株产果量提高。特别是ＵＦ２对ＵＦ１的加成效应表现出油茶年发育周期系列化学调控的协同作用对提高油茶单株产果量的积极意义。
The effects of UF1 and UF2 Camellia oleifera regulators on the chemical regulation of nutrition cycle and reproductive cycle in the developmental period of Camellia oleifera were studied and their relations with the yield formation were studied. The results showed that the growth of Camellia oleifera could be restrained by spraying UF1 at a certain period, but the numbers of shoots and branches were increased in the following year. Although the leaf area per plant was slightly reduced, the number and thickness of leaves Increase; flowering in the flowering period of Camellia UF2 (2 times), can significantly increase the rate of fruit set, reduce the rate of fruit drop, so that the yield per plant increased. In particular, the additive effect of UF2 on UF1 shows the synergistic effect of chemical regulation and control of the developmental period of Camellia oleifera on the yield of Camellia oleifera per plant.
