有机-无机缓释肥对番茄产量和氮肥利用率的影响

Effects of organic-inorganic slow release fertilizers on yield and nitrogen recovery in tomato

  • 摘要: 利用盆栽试验研究了有机-无机缓释肥料对番茄产量和氮肥利用率的影响。结果表明,与施用等NPK无机养分对照比较,施用缓释肥料B显著提高氮肥利用率,增加肥料氮在果实和叶片中的分配率;并且有利于后期产量形成,增产17.13%。施用缓释肥料A2提高氮肥利用率,增加肥料氮在根系和叶片中的分配率;并且有利于后期产量形成,增产16.33%。施用缓释肥料A2,氮肥利用率和产量的增幅均较小。

     

    Abstract: Pot experiment was conducted to investigate the effects of organic-inorganic slow release fertilizers on yield and nitrogen recovery in tomato.The results showed that the application of organic-inorganic slow release fertilizer B increased nitrogen recovery rate,and increased the distribution proportion of nitrogen in fruits and leaf; New type fertilizer B application improved the yield componet at latter stage,and increased yield by 17.13%.Application of organic-inorganic slow release fertilizer A2 was also increased the nitrogen recovery rate, raised the proportion of nitrogen in roots and leaf and increased yield by 16.33%.Organic-inorganic slow release fertilizer A2 was litter effect on nitrogen recovery rate and yield of tomato.
