生物有机肥在大棚重茬番茄上应用技术研究

Applied Technology of Bio-organic Fertilizer in Greenhouse Continuous Cropping Tomato

目的:明确生物有机肥等对番茄重茬病及其产量的影响,为实现番茄的安全、高效生产提供依据。方法:研究以耐寒性较强的“金粉218”番茄品种为材料,比较供试生物有机肥单施和与其他肥料混施的控病增产作用。结果:生物有机肥对番茄重茬病控制效果为86.82%,株高提高27.21%,茎粗增加35.90%,始花期提前7 d,开花数增加65.63%,成熟期提前7 d,单株结果数增加26.35%,平均单果重增加52.29%,增产幅度达80.57%。结论:土壤基施生物有机肥80 kg/667 m^(2)+微生态制剂5 kg/667 m^(2)+绿康威稀释液500倍叶面喷施3次番茄重茬病有较好的控制效果,增产效果明显,可在生产中应用。

This study investigated the effect of bio-organic fertilizer on the conotrol of continuous cropping disease and yield of tomatoes,aiming to provide a foundation for safe and efficient tomato production.Tomato variety‘Jinfen 218’,known for its strong cold tolerance,was used as material to explore the effect of bio-organic fertilizer on disease control and yield enhancement.The results showed that the bio-organic fertilizer demonstrated an 86.82%effevtiveness in controllin continuous cropping disease.The application of the bio-organic fertilizer led to a 27.21%increase in plant height,a,35.90%increase in stem diameter,a 7-day advancement in the initial flowering period,a 65.63%increase in flowering numbers,a 7-day advancement in mature period,a 26.35%increase in the fruit number per plant,a 52.29%increase in average fruit weight,and an 80.57%increase in overall yield.The application of bio-organic fertilizer 80 kg/667 m^(2)+microecological preparation 5 kg/667 m^(2)+500-fold diluted solution of Lycopersicon fulvum applied three times to tomato leaves,exhibited effective control against tomato continuous cropping disease,and resulted in significant yield improvement.
