摘　　要：【目的】为提高火龙果果实产量和果品的质量,提高火龙果种植户效益。【方法】选用南宁市各火龙果生产基地使用较多的四种不同光质LED灯对火龙果进行4批次补光效果试验,研究不同光质LED灯对火龙果促花效果、单果重、果实糖度、结果数和产量的影响。【结果】A灯四批火龙果补光催花效果均显著或最显著,D灯3批次显著,B、C灯2批次显著,各灯显著性大小依次为A、D、B、C灯;四种灯对火龙果果实糖度及单果重量影响不显著,对火龙果结果数和产量增产效果显著,显著性大小依次为A、D、B、C灯。【结论】本试验条件下,四种灯中A灯补光效果最显著,与A灯主要技术参数有关,A灯主波长(596.1 nm)最大,接近橙光波长范围(622~597nm)的下限,光通量最大(1485.671 Lm),峰值波长(603.3 nm)位于橙光波长范围,光效值接近100 Lm/w,建议在火龙补光种植中推广使用。【Objective】In order to improve the fruit yield and fruit quality,increase the efficiency of pitaya growers.【Method】Four kinds of LED with different light quality were applied in various pitaya production bases in Nanning City to carry out light supplementation effect test on pitaya fruit in 4 batches,to study the effect of LED with different light quality on flower acceleration,single fruit weight,fruit sugar con⁃tent,fruit number and yield of pitaya fruit.【Result】The effect of light supplement and flower acceleration was the most significant in four batches of pitaya fruit with lamp A,while the effect of light supplement and flower acceleration was significant in three batches with lamp D,and significant in two batches with lamp B and lamp C.The lamp order of effect significance is A、D、B、C.The effect of four kinds of lamps on sugar content and single fruit weight of pitaya fruit was not significant,while the effect of light supplement and flower acceleration was significant,the order of effect significant is lamp A,lamp D,lamp B and lamp C.【Conclusion】Under this test condition,the light supplement effect of lamp A is the most signifi⁃cant among the four kinds of lamps,which is related to the main technical parameters of lamp A.The main wavelength of lamp A(596.1 nm)is the largest,close to the lower limit of the orange wavelength range(622-597 NM),the maximum luminous flux(1485.671 LM),the peak wavelength(603.3 nm)is in the orange wavelength range,and the luminous efficiency value is close to 100 LM/W.It is suggested to pop⁃ularize the application of pitaya production.
