Research on LED Plant Illumination and Supplementary Light System for Fig Growth
When figs grew in the natural environment,because of the inability to control the light and other factors,there was a long growth cycle resulting in a long revenue cycle,slow benefits and other issues.In order to solve this problem,this paper researches the LED plant lighting light source and control system suitable for fig growth,and designed three kinds of plant lighting supplemental light system of pink violet light,pink light and full spectrum,compared with the figs grown under natural conditions irradiation,the three kinds of plant lighting LED products of pink violet light,pink light and full spectrum had a promotion effect on the growth of fig,and in the dormant period of figs in winter,the figs irradiated by the three kinds of plant lighting LED products,pink violet light,pink light and full spectrum all had a promotion effect on the growth of figs. In the fig dormant period,the figs had been irradiated by pink violet light,pink light,full spectrum plant lighting LED products were all in the fruiting period,obviously promoted the growth of figs.Especially,pink violet light plant lighting LED floodlights had obvious promotion effect.It can shorten the growth cycle of figs by about 20～30 days,and the mu yield is as high as about 100 kg of capacity compared with the growth of unsupplemented control group.The fruit is oval,fruit shape index 0.9～1.0,fruit fresh weight 75.3 g.Obviously playing an role in promoting the fruit colour and taste,the fruits colour are red and the shape are full.It is favourable for large-scale application to other greenhouses at a later stage.
