| 中文摘要: |
| 为了揭示配方施肥对葡萄生长期土壤物理性质和有效态中微量元素的动态影响，以4年生“醉金香葡萄”为试材，设计了9个配方施肥组合，测定了各组合醉金香葡萄5个不同时期的土壤容重、孔隙度、有机质、pH值及有效态钙、镁、铁、锌、锰的含量。结果表明：与常规施肥相比，配方施肥处理可提高酸性土壤pH、增加土壤孔隙度和有机质含量，降低葡萄土壤容重；在未施中微量元素肥料的前提下，配方施肥各处理均能在一定程度上维持土壤中微量营养元素的平衡；其中，采取每667m2施尿素40kg、磷酸一铵35kg、硫酸钾75kg、干鸡粪800kg综合表现最佳，能明显降低土壤容重，改善土壤pH，增加土壤孔隙度，且土壤有机质和有效态中微量元素含量最高。 |

| In order to reveal the effect of formula fertilization on soil physical properties and effective state medium trace element. 9 formulated fertilization treatments were designed. four-year-old ’zuijinxiang’ grape trees in field were used to determine the root zone soil bulk density, porosity, organic matter, pH value and the contents of available calcium, magnesium, iron, zinc, manganese in five different periods of each treatment. The results indicated that , compared with the conventional fertilization treatment. Formulated fertilization treatment could improve the acid soil pH . Increased the soil porosity and the content of organic matter. Reduced the soil bulk density in grape root zone. Without applying the Medium and trace element fertilization. Formulated fertilization treatments could maintain the balance of trace elements in soil. Among them, the application of urea 40kg, ammonium phosphate 35kg, potassium sulfate 75kg, dry chicken manure 800kg per 667m2 overall performance was the best, It significantly reduced the soil bulk density, improved the soil pH, Increased the soil porosity, Furthermore, the content of soil organic matter and effective state medium trace element were the highest |
