通过盆栽试验,研究施肥对草坪颜色、剪草量、蒸散量及土壤中速效氮的影响。结果表明:施N肥能够明显改善草坪的颜色,增加草坪的剪草量,提高草坪的蒸散量;苗期施P肥将导致草坪剪草量明显增加;当土壤中速效N和速效P供应充足时,施K肥导致草坪颜色和剪草量明显降低。单施N肥能够加快土壤中铵态氮的硝化过程,氮磷钾平衡施肥则能够延缓土壤中铵态氮的硝化过程,降低土壤中硝态氮的含量,从而降低土壤中硝态氮淋失的风险。草坪的蒸散量与剪草量之间存在着显著的线性正相关(r=0.9965);控释肥料和常规肥料之间养分释放模式存在很大差异,使得施肥初期常规肥料处理草坪颜色、剪草量及蒸散量均高于控释肥料处理,施肥末期情况则相反。 Pot experiments were conducted to study the effects of fertilization on lawn color, grass cutting volume, evapotranspiration and soil available nitrogen. The results showed that applying N fertilizer could obviously improve the color of lawn, increase lawn mowing volume and increase lawn evapotranspiration. Applying P fertilizer at the seedling stage resulted in a significant increase of lawn mowing grass. When soil available N and available P were abundant When applied K fertilizers lead to lawn color and cut grass significantly reduced. The application of N fertilizer can accelerate the nitrification process of ammonium nitrogen in soil, and the balanced fertilization of N, P and K can delay the nitrification process of ammonium nitrogen in soil, reduce the content of nitrate nitrogen in soil, and reduce nitrate leaching in soil risks of. There was a significant linear positive correlation between lawn evapotranspiration and grass cutting (r = 0.9965). There was a big difference in nutrient release patterns between controlled release fertilizers and conventional fertilizers, Amount and evapotranspiration were higher than the controlled release fertilizer treatment, fertilization at the end of the situation is the opposite.
