锌肥施用方式对番茄生长·果实品质及土壤理化性状的影响

Effects of Zinc Fertilizer Application Types on Tomato Growth,Fruit Quality and Soil Physical and Chemical Properties

[目的]筛选番茄最佳锌肥施用方式。[方法]采用随机区组设计,以迪安娜番茄为试验材料开展田间试验,在同等锌肥施用量的条件下,研究不同锌肥施用方式(底施、滴灌施肥、叶面喷施)对番茄生长、果实品质及土壤理化性状的影响。[结果]施用锌肥可以促进番茄生长,滴灌施肥的单果重比不施锌肥高19.50%,产量提高19.52%;滴灌施肥处理可以增加番茄果实中可溶性总糖、Vc和全锌含量,叶面喷施的果实全锌含量最高,与种植前相比,底施和滴灌施肥均可以提高土壤有效锌含量。[结论]增施锌肥可以促进番茄生长,提高产量和品质,滴灌施肥效果最佳。

[ Objective ] To choose the best type of zinc fertilizer application of tomato. [ Method ] Three treatments of ZnSQ ·7H2O were designed using random block design and taking ＂DiAnNa＂ as test material. Under the same zinc application amount, the effect of zinc fertilizer application types on tomato growth, fruit quality and soil physical and chemical properties was studied. [ Result ] Applying zinc fertilizer could promote the growth of tomato, fertigation obviously increased single fruit weight by 19.50% , increased yield by 19.52% , it also could improve the content of soluble total sugar, Vc and total zinc. The total zinc of spraying on the leaf was highest, compared with before planting, base fertilizer and fertigation could improve soil effective zinc content. [ Conclusion ] Applying zinc fertilizer could promote the growth, yield and fruit quality of tomato, and fertigation was the best.
