输液肥对柑橘果实品质的影响

Effects of Infusion Fertilizer on the Fruit Quality of Citrus

[目的]考察输液肥对柑橘果实品质的影响,并探索一种新的果树施肥方法。[方法]以四川柑橘为试验材料,分别通过树杈部及近根部施用不同浓度的输液肥,考察其对柑橘有机酸、总糖含量、Vc含量等品质的影响。[结果]结果表明,施用输液肥对植株的生长有明显促进作用,果实中糖酸比增大,Vc含量增加;不同部位施用不同浓度的输液肥,树杈部施用输液肥效果优于近根部施用输液肥,在树杈部施用6%的输液肥效果最佳。[结论]该研究为输液施肥技术在果树上的应用奠定了一定的基础。

[Objective] The research aimed to study the effects of infusion fertilizer on the fruit quality of citrus and explore a new kind of fertilization method for fruit tree. [Method] In the test with Sichuan citrus as tested materials, the infusion fertilizer with different concentrations were applied in the branches and near the root respectively to investigate its effects on the qualities of citrus such organic acid, total sugar content and Vc content. [Result] Applying infusion fertilizer had obvious promotion effects on the growth of plants, the ratio of sugar to acid was enlarged and Vc content was increased. The infusion fertilizer with different concentrations should be applied in different parts, The effect of applying infusion fertilizer in the branches parts was better than that applying infusion fertilizer near the root. The effect of applying 6% infusion fertilizer in the branches was best. [Conclusion] The research laid certain foundation for applying infusion fertilization technology to fruit trees
