摘要
为研究不同时长LED灯补光对火龙果生长的影响,在广西南宁市隆安县选用同一种火龙果LED补光灯进行4个不同时长(3h、4h、5h、6h)的补光试验。结果表明,补光时长4h或5h较好,虽然两种方式预估产量差异不显著,但4h预估产值相对较高,且比补光5h节省电能,较为可观地节省成本;不同时长补光对火龙果单果重及糖度差异不显著。
In order to study the effects of different duration LED lights on the growth of pitaya,the same kind of Pitaya LED lights were selected for four different time duration(3 h,4 h,5 h,and 6 h)lighting experiments in Long’an County,Nanning,Guangxi.The results show that 4 h or 5 h is better for fill light.Although there is no significant difference between the two methods,the 4 h estimated output value is relatively high,and 1 h electric energy is saved compared with 5 h lighting,which saves the cost considerably.Different duration of light supplementation has no significant difference in weight and sugar content of pitaya.
