缓释配方肥对加工番茄产量和品质及效益的影响

Influence of Slow-release Formula Fertilizer on Yield,Quality and Efficiency of Processing Tomato

以加工番茄"屯河8号"为试材,以常规施肥为对照,研究了配方肥、缓释配方肥及其减量和氮磷缺素处理对加工番茄养分吸收、产量、施肥效益的影响,以期明确加工番茄肥料配方的科学性及长效缓释添加剂(NAM)的应用效果,为加工番茄缓释配方肥的推广应用提供参考依据。结果表明:相同栽培条件下,缓释配方肥及其20%减量处理促进了加工番茄植株生长,植株的氮、磷吸收量均有增加,产量比常规施肥分别增加了4.12%和7.86%,纯收益增加了4.67%和8.71%,同时增加了果实中番茄红素含量和可溶性固形物含量,添加NAM条件下应降低配方肥中的氮素用量。

Taking ＇ Tunhe No. 8＇ processing tomato as material, compared with conventional fertilizer objective, the effect of the formula fertilization and slow-release formula fertilization and its reduction, nitrogen and phosphorus deficiency treatment on yield, quality and fertilizer efficiency of tomato were studied, in order to clear the scientific and the application processing tomato fertilizer formula, to provide a reference for application of slow release formula fertilization. The results showed under the same cultivation conditions, slow-release formula fertilization and its 20% decrement treatment promoted the growth of the processing tomato plants, the uptake of nitrogen and phosphorus plant were increased, the yield were increased by 4. 12 % and 7. 86 % than conventional fertilization, net income increased by 4. 67 % and 8. 71% ,while increasing the lycopene content and soluble solids content in fruit,under the condition of adding NAM, the dosage of nitrogen in the formula fertilization should reduce.
