硝酸磷(钾)肥在烤烟生产上的应用研究

Nitrate Phosphate (Potassium) fertilizer on flue-cured tobacco production at the Applied Research

通过田间试验示范,研究了硝酸磷钾肥对烤烟产量、品质及经济性状的影响。结果表明:与常规施用复合肥比较,硝酸磷(钾)肥提高烟叶的均价、亩产值和上等烟比例,改善烟叶质量,提高中、上部烟叶的钾含量,降低还原糖和总糖的含量,并且,降低投入成本,经济效益十分显著。

The demonstration field experiment to study the nitrate phosphate (potassium) fertilizer of flue-cured tobacco production, quality and economic characters. The results showed that: compared with the conventional application of compound fertilizer, nitric acid phosphate (potassium) fertilizer to raise the average price of tobacco, cigarette yield the proportion of first-class values and to improve the quality of tobacco leaves, improve, the upper leaves of the potassium content, reducing sugar and total reducing sugar content, and reduce input costs, significant economic benefits.
