[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 screen the best way of zinc fertilizer application in tomato. [Method] Randomized block design was used to carry out field experiment with Deanna tomato as material. Under the condition of the same amount of zinc fertilizer, the effects of different Zn fertilizers (topdressing, drip irrigation and foliar spraying) Growth, fruit quality and soil physical and chemical properties. [Result] The application of zinc fertilizer could promote the growth of tomato. The single fruit weight of drip irrigation was 19.50% higher than that of no zinc fertilizer and the yield was increased by 19.52%. The drip fertilization could increase the content of total soluble sugar, Vc and total zinc in tomato fruit, The highest content of zinc in the fruits was sprayed. Compared with the pre-planting, both top-dressing and drip irrigation could increase the effective zinc content in soil. [Conclusion] The application of zinc fertilizer could promote the growth of tomato, increase the yield and quality, and the drip irrigation was the best.
