| 摘 要： | 为了对烟区实施定位、定量的精准田间养分管理提供理论依据,利用DGPS技术进行网格定位取样、GIS技术进行土壤养分分析和管理,以形成烤烟精准施肥配方,进行推荐施肥.结果表明,精准配方肥料对烟株田间长势、产量和烤后烟叶化学品质影响不大,但烟叶产值、均价和上等烟率分别提高了2.4％、3.0％和3.6％,肥料投入成本平均降低220元/t.结论:根据土壤肥力和烤烟营养规律进行的精准施肥,能协调烟株营养,直接减少肥料成本投入,间接提高肥料利用率和增加烟农收入. |
| 关 键 词： | 烤烟 精准施肥 应用 节本增效 |

| Abstract: | To provide a theoretical basis for tobacco-planting area location and field nutrient management with precision fertilization,the DGPS technology was used to locate grid sampling,and the GIS technology was used to analyze and manage the soil nutrients,then form the flue-cured tobacco precision fertilization scheme.The results showed that precision fertilization had little effect on tobacco growth,chemical production and quality,However,the yield,mean price and first-class tobacco rate were increased by 2.4 %... |
