壳寡糖与海藻酸对番茄产量及品质的增效研究

以番茄为试材,采用盆栽试验,研究对比了在水溶肥中添加不同种类和不同浓度的增效剂对番茄生长及果实的影响,以期为实际生产提供参考依据,也为壳寡糖和海藻酸在农业方面更深入的应用奠定基础。结果表明:挂果初期施用添加0.4%的壳寡糖效果最好,能够显著提高挂果初期的结果数;在果实的生殖生长期施用添加0.1%的壳寡糖效果最好,能够显著提高番茄果实的果实横径、果实产量以及果实的转色率。该试验设计的浓度梯度对于番茄的可溶性固形物、可溶性糖各处理之间没有显著差异,果实维生素C含量方面各增效剂的各添加量处理均显著高于对照处理。但综合添加各浓度的壳寡糖和海藻酸处理的均值来看,添加海藻酸更能够促进果实维生素C的积累。

Study on Synergism of Chitooligosaccharides and Alginic Acidon Tomato Yield and Quality

Taking tomato as the test material,and a pot experiment was used to study and compare the effects of adding different types and different concentrations of synergists to water-soluble fertilizers on tomato growth and fruit,in order to provide a certain reference for actual production and pave the way for more in-depth applications of chitooligosaccharides and alginic acid in agriculture.The results showed that the effect of adding 0.4%chitooligosaccharide in the early stage of fruit bearing was the best,which significantly increased the number of fruit in the early stage of fruit bearing.Adding 0.1%chitooligosaccharide in the reproductive growth period of the fruit had the best effect,which could significantly increase the fruit transverse diameter,yield and color change rate.The soluble solids and soluble sugars of tomato in this experiment did not differ significantly between the treatments,and the vitamin C content of the fruits treated with each added amount of each synergist was significantly higher than that of the control treatment.However,based on the average value of adding various concentrations of chitooligosaccharides and alginic acid,the addition of alginic acid was more conducive to the accumulation of vitamin C in the fruit.
