肥料除了对作物有增产的效果外,在改良土壤结构、维持土壤营养相对平衡方面的作用也不容忽视。众所周知,过量施用化肥能降低土壤肥力,还会引起环境污染。本研究采用不同类型的肥料进行对比试验,探讨肥料对土壤肥力状况变化的影响,为蔬菜生产合理选择肥料提供依据。1 材料
In addition to fertilizers have the effect of increasing yield of crops, the role of improving soil structure and maintaining the relative balance of soil nutrients can not be ignored. It is well-known that excessive application of fertilizers can reduce soil fertility and cause environmental pollution. In this study, different types of fertilizers were used to conduct comparative experiments to explore the effect of fertilizers on the changes of soil fertility and to provide evidence for the rational selection of fertilizers for vegetable production. 1 material
