Abstract:

Large-scale greenhouses in China have developed rapidly and are mainly used for tomatoes and other fruits and vegetables. Due to the lack of systematic light supplement schemes, the yield and benefits are greatly affected. In order to explore a suitable light supplement for large-scale greenhouses in China, it was made an example in Zhuhai to explore the light supplement for long-season cultivation mode of large-scale greenhouse tomatoes in this article. Based on the analysis of natural light data in Zhuhai from 1997 to 2016, and the distribution of natural light in greenhouse and light demand of tomato, the design method of long-term cultivation of tomato in Zhuhai large greenhouse was put forward. When tomatoes are at the vegetative growth and fruit setting stage, appropriate light supplementation should be carried out according to the natural light environment at that time. The light supplementation intensity is 102-166 μmol/m2·s. Natural light has been fully considered, so less artificial light is used to make up for the shortage of natural light. This method can be used as a reference for light supplement design of other greenhouses.

Key words: the natural light, long-season cultivation of tomato, artificial light
