升降式系统补光对弱光条件下日光温室番茄生长及产量品质的影响

Effects of lifting supplementary lighting on growth,quality and yield of tomato with weak light in greenhouse

在冬季日光温室弱光环境下,以番茄"金鹏1号"为试材,采用带有机械遥控升降系统的SON—TArgo,发光效率达130lm/W的植物生长钠灯对番茄植株进行不同光源配置高度及时间的补光处理,研究升降式系统补光对弱光条件下日光温室番茄生长及产量品质的影响。结果表明:通过可升降式补光系统实现对光照强度的机械调节,补光处理促进番茄植株光合作用及生长发育、提早成熟、提高果实产量及品质。

With the weak light of solar greenhouse in winter, supplementary lighting was treated on tomato ＂Jinpeng NO. 1＂ by using SON--Targo, which has remote lifting system. Different illuminant height and supplementary lighting time were considered in the test, and sodium lamp with 1301m/W luminous efficiency was adopted, thus, effects of lifting supplementary lighting on growth, quality and yield of tomato were studied. The results show that lifting supplementary lighting system can realize the mechanical ad- justment of illumination, and supplementary lighting can promote the photosynthesis, growth, early maturity, yield and quality of to- mato.
