Effects of Different Supplementary Light on Growth and Photosynthetic Characteristics of Strawberry in Greenhouse
Taking the'Miaoxiang 7'strawberry as the test material,a strawberry supplementary light experiment was conducted at the 69th greenhouse base.Four common supplementary light types were set up,red blue ratio 9∶1 waterproof LED supplementary light(T1),full spectrum waterproof LED plant supplementary light(T2),red blue light ratio 5∶1 waterproof LED supplementary light(T3),and no supplementary light(CK).The effects of different types of supplementary light on the growth,development,and photosynthetic characteristics of greenhouse strawberries were explored.The membership function method was used to comprehensively evaluate indicators such as strawberry fruit quality and yield,and the optimal treatment was selected,in order to provide reference for high-quality production of greenhouse strawberries in Yili region.The results showed that different supplementary light treatments could increase the size and thickness of strawberry leaves,increase chlorophyll content,and improve the photosynthetic parameters of strawberry plants,which was beneficial for strawberry growth and development.It could also increase the single fruit weight,soluble sugar content,vitamin C content,and soluble solids content of the fruit,improve fruit quality,and increase yield.In summary,the red blue ratio of 9∶1 waterproof LED supplementary light was more beneficial for strawberry growth and development,improving fruit quality,and increasing yield as a greenhouse strawberry supplementary light source.
