Abstract: Abstract: In order to improve the Camellia fruit retention rate, nutrient elements and plant growth regulator were sprayed to Camellia oleifera Abel . The results showed that: the treatment methods had significant differences at 0.05 level for Sihui Camellia oleifera Abel, and the fruit retention rates of 10mg/L 2,4-D and 0.3% urea treatment were the highest, which reached 63.33%. Effect of different treatments on the fruit, partial treatment had significant differences with blank control for the fruit weight, diameter, thick skin, seeds, fresh seed weight, the average values of fruit weight and fresh seed weight of deweile plant nutrients 800 times were 2.87, 3.13 times to blank control. For Guangdong academy of forestry Camellia oleifera, the fruit retention rates of 30mg/L NAA +0.3% urea treatment was the highest, reached 63.33%, but the treatment methods had no significant differences at 0.05 level. Effect of different treatments on the fruit, each treatment of other index had no significant difference with blank control in addition to transverse diameter
