| 摘 要： | 通过田间试验研究了施用不同螯合态液肥对大棚番茄产量、品质以及土壤理化性状的影响。结果表明,在等量施肥条件下,各处理的番茄产量无显著差异,较对照均有一定程度的增加;冲施中浓度液肥番茄的VC含量较高,并且硝酸盐含量最低;土壤硝态氮含量最高,铵态氮含量也较高,碱解氮含量最高,速效磷含量最低,速效钾的含量升高,表明在常规水肥条件下,冲施中浓度的液肥不仅能提高番茄品质,而且能够提高氮素有效性,减少磷素在土层中的积累以及增加钾的积累,改善土壤供肥能力。

| Abstract: | The field experiment was conducted to study the effect of chelate liquid fertilizer application on the yield and quality of tomato and the physical and chemical characters of soil in plastic greenhouse.The results showed that under the same application rate of fertilizer,there were no significant differences in tomato yields among the trials,which were all higher than that of CK.The tomato treated by medium-concentration liquid fertilizer with irrigation had more vitamin C and the lowest nitrate content,and also the highest nitrate-N and alkali-hydrolyzable N,higher ammonium-N content and available potassium content and the lowest available phosphorus in soil.In one word,under the conventional water and fertilizer supply,the application of medium-concentration liquid fertilizer with irrigation could not only improve tomato quality,but also enhance the N effectiveness,reducing P accumulation in soil layers and improving K accumulation. |
