品质改良剂在大棚番茄上的应用效果

以自主研发的品质改良剂为试材，测定其不同浓度处理对番茄果实产量、果实膨大速率、果实着色率、番茄红素、VC等相关指标的影响。试验结果表明，经品质改良剂处理的番茄果实较CK平均提前12 d达到采收标准。品质改良剂1 000倍液处理的产量达到91 380 kg?hm-2，较CK增产15.71%|还原糖、VC和番茄红素含量分别是CK的2.55、2.51倍和1.57倍，可滴定酸含量降低了0.06个百分点。表明该品质改良剂可以促进番茄果实膨大与着色，提高果实品质。

Studies on Application Effect of Fruit Quality Improver in Greenhouse Tomato

The experiment was conducted taking the fruit quality improver independently researched and developed as material,so as to test the effect of different improvers concentration on tomato(Lycopersicon esculentum Mill.)fruit production,fruit expanding rate,fruit color changing rate,lycopene and VC contents,etc.The results indicate that the treated fruits reach the harvest standards 12 days earlier than CK.The yield with improver 1 000 times treatment reaches 91 380 kg·hm-2,which is 15.71% higher than that of CK.The titration acid content is 0.06 percent point lower than CK,and the contents of soluble sugar,VC and lycopene are 2.55 times,2.51 times,and 1.57 times of CK,respectively.All these results show that the improver can promote the color reforming and fruit expansion of tomato,and thus improve the fruit quality.
