氨基酸混合物对烤烟产质影响的研究初报

Preliminary study on influence of amino acid mixture on yield and quality of flue-cured tobacco

烤烟上喷施氨基酸混合物可促进烟株生长，增加产值，提高桔黄色烟、上等烟比例，明显改善烤烟品质。以团棵期、旺长期、现蕾期各叶面喷施１次４‰氨基酸混合物液体效果为佳。在中下部叶的应用效果优于上部叶；在低肥力水平烟田的应用效果优于中高肥力水平的烟田。

The experimental results demonstrated that:While tobacco was growing,spraying amino acid mixture could improve tobacco growth,raise output value and the proporation of orange and fine leaf,it could also improve the quality obviously.Spray of amino acid liquid at the 4‰ concentration once during rosette stage,fast growing period and flower bud appearing period respectively had the best effect.The effect of spraying on the middle and lower leaves was better than that on the upper leaves.The effect of spraying in the field with lower fertility was better than that in the field with middle and higher fertility.
