摘要
为了探索秸秆源提取物在番茄上的适宜的喷施时期,以冬春茬日光温室番茄"皇家优秀"为试材,研究了秸秆源提取物不同施用时期对番茄生长、产量和品质的影响。结果表明:喷施秸秆源提取物后能够促进番茄植株生长,番茄产量略有增加,其中T1(初花期)处理产量最高为8 190kg/667m2;喷施后番茄果实品质显著提高,T1(初花期)、T2(坐果期)和T3(果实膨大期)处理与CK相比,维生素C含量分别提高59.2%、36.0%、39.7%;可溶性糖含量分别提高41.4%、37.3%、34.4%,番茄红素含量分别提高53.4%、17.7%和28.3%,处理间达到了显著性差异。综合产量和品质等指标,T1处理(初花期)是该试验条件下番茄种植中秸秆源提取物较适宜的施用时期。
In order to explore the straw extract suitable application time,the effect of different growth stages applying straw extract on greenhouse tomatoes growth,yield and quality were analyzed.The results showed that spraying straw extracts could increase plant growth,productivity and improve quality.T1 treatment had the highest yield of8 190kg/667m2;T1,T2 and T3treatments compared with the control group,the content of vitamin C were increased by59.2%,36.0%,39.7%;the soluble sugar content increased by 41.4%,37.3%,34.4%,respectively.Lycopenecontent increased by 53.4%,17.7% and 28.3%.Comprehensive yield and quality indexs,T1(flowering stage)period was the suitable application time to apply straw extract.
