摘要
为提高油茶保果率,对普通油茶喷施营养元素和植物生长调节剂,结果表明:对于四会普通油茶,各处理方法在0.05水平上差异显著,且10mg/L2,4-D和0.3%尿素的处理保果率最高,都达到63.33%,各处理对果实的影响,对于单果重、横径、果皮厚、籽数、鲜籽重这些指标,部分处理跟空白对照有显著差异,其中德威乐植物营养剂800倍处理单果重和鲜籽重平均值分别是空白对照的2.87、3.13倍;对于广州普通油茶,30mg/L萘乙酸+0.3%尿素处理保果率最高,达63.33%,但各处理方法在0.05水平上差异不显著,各处理对果实的影响,除了横径,其他指标的各处理跟空白对照没有显著差异。
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 10 mg/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 Guangzhou Camellia oleifera , the fruit retention rates of 30 mg/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.
