摘要
为了探索新型稀土转光膜(RPO)在日光温室番茄上的应用效果,以口感型番茄品种津杂902、津杂903和硬粉型品种津杂340为试验材料,以普通棚膜(PO)为对照,研究稀土转光膜对日光温室环境下秋延茬番茄植株生长和果实品质的影响。结果表明,与PO相比,RPO处理使番茄的始花期提早0~5 d,盛花期提早9~13 d,结果期提早6~8 d。在RPO处理下,温室内的最高光照强度高于对照19.36%~39.33%;11月最低温度增幅41.35%;供试品种津杂902、津杂903、津杂340叶片叶绿素相对含量分别比PO处理显著提高了8.27%、7.53%、14.34%;维生素C含量分别比PO处理显著提高了76.92%、24.66%、97.24%;可溶性固形物含量分别比PO处理显著提高了5.38%、10.43%、21.95%;可滴定酸含量分别比PO处理显著降低了12.63%、23.32%、46.48%;平均单果质量分别比PO处理显著提高了44.00%、83.03%、28.44%。综上,RPO处理有效改善了日光温室的温光环境,促进秋延茬番茄植株生长,提高了果实品质和单果质量,可在生产中推广应用。
In order to explore the application effects of the novel rare-earth photoconversion film(RPO)on tomato in solar greenhouse,the taste-type tomato variety Jinza 902 and Jinza 903,and the hard-powder type variety Jinza 340 were used as experimental materials.With the common greenhouse film(PO)as the control,the effects of the rare-earth photoconversion film(RPO)on the growth of autumn-delayed tomato and fruit quality in solar greenhouse were studied.The results showed that compared with the PO treatment,the RPO treatment advanced the initial flowering stage of tomato by 0-5 days,the full-bloom stage by 9-13 days,and the fruiting stage by 6-8 days.Under the RPO treatment,the maximum light intensity in the greenhouse was 19.36%-39.33%higher than that of the control;the minimum temperature in December increased by more than 41.35%.The relative chlorophyll content in the leaves of the tested varieties Jinza 902,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 titratable acid content were significantly decreased by 12.63%,23.32%,and 46.48%,respectively;the average single fruit mass was significantly increased by 44.00%,83.03%,and 28.44%respectively compared with the PO treatment.In conclusion,the RPO treatment effectively improved the temperature and light environment in the solar greenhouse,promoted the growth of autumn-delayed tomato plant,and improved the fruit quality and single fruit mass,which can be popularized and applied in production.
