AbstractTo investigate theefects of different colored plastic mulches on strawberry growth and fruitquality,the primary strawberry cultivar Hongyan was studied under multi-span tunnel conditions.5 mulch treatments were applied, including black(CK), white (T1),silver-gray (T2),red (T3),andblue (T4)plastic mulch treatments under multi-span arched unnels.Thestudy examined their efects on strawberysoil temperature,photosynthetic characteristics,growth anddevelopment,fruitqualityandfieldecology.Resultsindicatedthatthesoiltemperatureenhancementefectofll treaments ranked as T1>T3>T4>T2>CK ,with the average soil temperature at all depths in the T1 treatment being 4.42-4.50∘C higher than in CK.Regarding photosynthetic traits,T3 exhibited the highest leaf chlorophyll content (SPAD value 53.51) and net photosynthetic rate [7.89 μmol CO ], while T2 showed the lowest values. In growth characteristics,T3 hadtheshortesttimetofirstflower(49days)andfruit maturity(51.2days),with significantlysuperior flowerand fruit numbers,plant height,and leaf area compared toother treatments,whileexhibiting fewer malformed fruits than CK.Regarding fruit quality,T3 showed thehighestaverage fruit weight (33.6 g).Soluble solids content exceeded CK in all treatments,with T4 exhibiting optimal fruit vitamin C content (0.552mg/g) ).Fruit brightnesswas significantly higher inT2thaninother treatments.In termsoffieldecology，silver-grayandblack mulcheffectively suppressed weed growth,while white mulch had the highest weed density and substrate moisture.Overallred mulch showedthe bestcomprehensive effectinpromoting strawberrygrowth,shorteningthegrowth period,and increasing yield.Silver-gray mulch improved fruit appearance,and blue mulch enhanced fruit VC content.Inproduction,suitable mulch can be selected based on variety characteristics and cultivation requirements.
