Abstract：Inorder toexplore theapplication effectsof the novelrare-earth photoconversion film（RPO）on tomato n solar greenhouse，thetaste-typetomatovarietyJinza902andJinza903，andthehard-powdertypevarietyJinza340 were usedas experimentalmaterials.Withthecommongreenhousefilm（PO）asthecontrol，theeffectsof therare-earthphotoconversion film（RPO）on the growth of autumn-delayed tomato and fruit quality in solar greenhouse were studied.The results showed thatcompared with thePO treatment，theRPO treatment advanced the initial flowering stage of tomato by 0-5 days，thefull-bloomstageby9-13days，andthefruiting stageby6-8days.Under theRPOtreatment，the maximum light intensity in the greenhouse was 19.36% 39.33% higher than that of the control; the minimum temperature in Decemberincreasedbymore than 41.35% .Therelativechlorophyll content in the leaves of the tested varieties Jinza9O2，Jinza 903，and Jinza 340 were significantly increased by 8.27% 7.53% ，and 14.34% ，respectively compared with the PO treatment; the vitamin C content were significantly increased by 76.92% 24.66% and 97.24% ，respectively; the soluble solids content were significantly increased by 5.38% 10.43% ，and 21.95% ，respectively;the titratableacid content were significantly decreased by 12.63% 23.32% ，and 46.48% ，respectively;the average single fruit masswassignificantly increased by 44.00% ， 83.03% ，and 28.44% respectively compared with the PO treatment.In conclusion， the RPO treatment effectivelyimproved the temperature and light environmentinthesolar greenhouse，promoted the growthofautumn-delayed tomato plant，and improved thefruit qualityandsingle fruit mas，which canbe popularizedandapplied in production.

光照是影响植物生长发育的重要因素之一，不同光质对植物的形态建成、生理代谢及果实品质等均有调控作用1]，但并非阳光中所有波段的光线都对植物生长有益，对植物生长发育起关键作用的主要是蓝紫光和红橙光。（剩余5835字）
