不同整枝方式对管棚越夏栽培番茄生长的影响

Effects of Different Pruning Treatments on Growth of Over-summer Cultivating Tomato

在管棚田间状况下,对越夏栽培的番茄进行单秆整枝、双秆整枝及连续摘心处理,测定番茄的生长、产量及品质指标,研究不同的整枝方式对越夏栽培番茄生长的影响。研究结果表明,连续摘心处理的植株在株高、茎粗、产量、叶绿素含量及根系活力指标方面均优于单秆整枝和双秆整枝处理;双秆整枝处理的植株叶片中丙二醛含量最高,番茄果实中VC含量也有所增加;连续摘心能够提高番茄果实中可溶性蛋白含量;单秆整枝能够提高番茄红素含量。综合不同整枝方式对番茄各个生长指标的影响,连续摘心整枝方式对促进管棚越夏栽培番茄生长效果更佳。

In order to learn the effects of different pruning treatments on growth of over-summer cultivating tomato,three different pruning treatments were applied to tomato seedlings in the greenhouse,and the growth,yield and quality indices of tomato were measured.The results showed that continuous decapitation treatment can significantly increased the height,yield,chlorophyll content and root activity of tomato seedlings,compared to the other two pruning treatments.The MDA content in leaves and VC content in fruits were increased significantly by two-branch-pruning treatment.The Soluble protein content in tomato fruits was increased significantly by continuous decapitation treatment,and the lycopene content of tomato fruits increased significantly by one-branch-pruning treatment.In general,the continuous decapitation was the best pruning method for over-summer tomato cultivation.
