一种用于烟草覆膜待栽技术的专用复合肥料及其使用方法
摘要：
本发明涉及肥料技术领域，提供了一种用于烟草覆膜待栽技术的专用复合肥料，包括如下重量份数的原料：粉状尿素9.5‑11.5份，粉状磷酸二氢铵20‑24份，粉状硫酸钾40‑60份，粉状七水硫酸镁5‑8份，粉状七水硫酸锌4‑7份，硼砂1‑4份。本发明还提供了一种用于烟草覆膜待栽技术的专用复合肥料的使用方法。本发明的优点在于：本发明在专用复合肥料中，以酰胺态氮和铵态氮代替常规配方中的硝态氮，不仅能满足烟草生长所需，还能同时达到降低肥料成本的效果；此外，与本发明专用复合肥料相配合的使用方法步骤也相对简单、方便，具有非常好的应用前景。
摘要（英）：

The invention relates to the technical field of fertilizers, and provides a special compound fertilizer for technologies for mulching films for tobaccos to be cultivated. The special compound fertilizer comprises, by weight, 9.5-11.5 parts of powdery urea, 20-24 parts of powdery ammonium dihydrogen phosphate, 40-60 parts of powdery potassium sulfate, 5-8 parts of powdery magnesium sulfate heptahydrate, 4-7 parts of powdery zinc sulfate heptahydrate and 1-4 parts of borax. The invention further provides a method for applying the special compound fertilizer for the technologies for mulching thefilms for the tobaccos to be cultivated. The special compound fertilizer and the method have the advantages that nitrate nitrogen in conventional formulas is replaced with amide nitrogen and ammoniumnitrogen in the special compound fertilizer, accordingly, growth requirements of the tobaccos can be met, and effects of reducing the cost of fertilizers can be realized; the method which is matched with the special compound fertilizer includes relatively simple and convenient steps and has an excellent application prospect.
