激光补光对日光温室草莓生长发育、光合特性及产量的影响
Effects of Laser Supplementary Lighting on Growth,Photosynthetic Characteristics,and Yield of Strawberry in Solar Greenhouses
摘要
Abstract
To explore the effects of laser supplemental lighting on strawberry overwintering produc-tion in solar greenhouses in Jilin province,cultivar"Benihoppe"was used as the experimental mate-rial.Different laser supplemental lighting intensities were set[T1:1 µmol/(m²·s),T2:2 µmol/(m²·s),T3:3 µmol/(m²·s)],with ck as the control without supplemental lighting to study their effects on phe-nological phases,growth and development,photosynthetic characteristics,and yield.The results showed that appropriate laser supplemental lighting significantly promoted strawberry growth and de-velopment,increased net photosynthetic rate,and enhanced fruit yield.Among them,T2 performed the best in all indicators,with significant increases in plant height,stem diameter,leaf number,and inflorescence number.It also had the highest net photosynthetic rate,and the yield per plant reached 519.30 g,which was 23.52%higher than ck.Additionally,T2 showed a significant advantage in early-stage yield.However,a higher supplemental lighting intensity[3 µmol/(m²·s)]inhibited plant growth during the early stage,resulting in lower initial yield.Therefore,an optimal laser supplemen-tal lighting intensity of 2 µmol/(m²·s)can effectively improve overwintering production performance of strawberry,providing a theoretical basis for the application of supplemental lighting technology in protected agriculture.关键词
