摘要: 研究黄腐酸钾肥料在设施番茄上的最佳用量,以设施番茄为试材,采用田间小区试验,研究不同黄腐酸钾用量对番茄产量、品质及土壤理化性质的影响。结果表明:底施黄腐酸钾肥料,番茄产量、植株干物质量和根系生物量分别平均提高了14.0%、14.4%和50.6%;番茄的Vc 和可溶性糖分别增加了15.5%和10.0%;土壤容重平均降低了3.6%,土壤CEC增加了5.0%。并且各项指标随着黄腐酸钾施用量的增加而有所提高,当黄腐酸钾施用量达到4500 kg/hm2时,各项指标达到最高值。在考虑到肥料成本和各项指标,本研究推荐黄腐酸钾肥料作为底施的最佳用量为4500 kg/hm2。

Abstract: To study the optimum dosage of potassium fulvate (PF) on greenhouse tomato, the effects of different amount of PF on yield and quality of greenhouse tomato and soil physical and chemical properties were investigated by a field plot experiment. The results showed that the bottom application of PF increased tomato yield, plant dry matter quantity and root dry matter quantity by 14.0%, 14.4 and 50.6%, repectively; Vc and soluble sugar content of tomato increased by 15.5% and 10.0%; bulk density decreased by 3.6% and CEC increased by 5.0%. All the indexes increased with the increase of PF application amount, and reached the maximum value when the PF application rate was 4500 kg/hm2. In consideration of the cost of fertilizer and all indexes, the optimum dosage of PF fertilizer was 4500 kg/hm2.
