不同灌溉策略对樱桃番茄生长和果实性状的影响

为了研究不同灌溉策略在樱桃番茄上的应用效果,以樱桃番茄“凤珠”为供试材料,设置多量少次灌溉策略和少量多次灌溉策略试验处理,比较分析不同处理樱桃番茄的植株生长、品质以及产量指标。结果表明:与多量少次灌溉相比较,少量多次灌溉能促进植株生长,茎粗、叶宽、叶片叶绿素相对含量、平均单果质量分别增加16.4%、13.1%、8.4%、13.3%,果实可溶性固形物、维生素C、番茄红素含量分别增加6.4%、7.0%、20.6%,667 m^(2)产量和收入分别增加14.08%和2486.4元;少量多次灌溉不仅能促进植株生长,提高果实口感、营养品质和产量,而且能降低肥料淋溶风险,有助于科学指导樱桃番茄种植。

Effects of Different Irrigation Strategies on Growth and Fruit Traits of Cherry Tomato

Abstract: In order to study the application effects of different irrigation strategies on cherry tomato, treatments of low frequency with high amounts and high frequency with low amounts were set up by taking the cherry tomato cultivar ''Fengzhu'' as the experiment material, the indexes of tomato plants'' growth, fruit quality and yield were compared and analyzed. The results showed that compared with treatment of low frequency with high amounts, treatment of high frequency with low amounts could promote plant growth, the stem diameter, leaf width, leaf chlorophyll relative content and average fruit weight increased by 16.4%, 13.1%, 8.4%, 13.3%, respectively. The contents of soluble solids, vitamin C and lycopene increased by 6.4%, 7.0% and 20.6%, respectively, and the yield per 667 m2 and profit per 667 m2 increased by 14.08% and 2 486.4 yuan, respectively. The mode of high frequency with low amounts could not only promote plant growth, improve fruit taste, nutritional quality and yield, but also reduced the risk of fertilizer leaching, which was helpful for scientific guidance for cherry tomato planting.
