| 摘 要： | 在油茶试验基地设定15个处理，分别在花期喷洒不同类型及浓度的药物进行保花保果处理，并以喷洒清水为对照；采收成熟果实，测定其产量和单果重、横纵径、籽粒重等果实指标，进行生物统计分析，并结合喷洒成本，计算经济效益，筛选出海南油茶最适宜的保花保果药物及浓度。结果表明：0.5%硼砂、20 mg/L GA3、800倍爱多收和0.1%硼砂＋800倍爱多收＋800倍高美施处理的株产量显著高于对照组；0.5%硼砂处理的果实横纵径显著高于对照组；20 mg/L GA3、0.1%硼砂、800倍爱多收处理的单果重显著高于对照组

| Abstract: | Tea-oil camellia (Camellia olerfera) trees in the Tea-oil Camellia Experiment Station were divided into 15 groups for treatments. They were sprayed with chemicals at different concentrations at the flowering stage to protect the flower and fruit, with water spraying as a control. The ripe fruits were harvested to measure their fruit indexes such as yield, single fruit weight, longitudinal and transverse diameter, seed weight, etc. The indexes were used for biometric analysis, based on which the economic benefit was calculated by deduction of the cost of the chemicals used for spraying to screen out optimum chemicals and their concentrations for retention of flower and fruit of tea-oil camellia in Hainan. The treatments 0.5% borax, 20mg/L gibberellin, 800 times of dilution of Atonik, 0.1% borax +800 times of dilution of Atonik +800 times of dilution of Komix gave significantly higher yield per tree than the control; the 0.5% borax treatment had a significantly higher transverse and longitudinal diameter of fruit the control; the treatments 20mg/L gibberellin, 0.1% borax, and 800 times of dilution of Atonik produced obviously higher single fruit weight than the control; no significant difference was found in seed weight and seed output rate between each treatment and the control. This indicates that gibberellin, borax, atonik and komix have a significant role in improving yield and fruit weight of camellia. These chemicals are low in price and very easily accessible, and hence have a high promotion value in improving the economic benefits of tea-oil camellia in Hainan. |
