提高山东烟叶钾含量配套措施的研究

本文采用专用控释肥、生长调节剂、成熟期灌溉等技术措施探讨提高山东烟叶钾含量的有效途径。结果表明,专用控释肥K1有利于烟株对钾的吸收,增加株高、节距和叶长,提高烟叶对气候斑、野火病、TMV和CMV的抗性,对改善烟叶香气质、燃烧性和灰色有一定作用。旺长期施用芸苔素使野火病的病情指数和氯含量有所降低,上等烟比例、均价、产量和产值均有所提高。成熟期灌溉使烟叶氯含量有所降低,但病害有所加重。

The field experiment using slow release fertilizer,growth regulator and irrigation in mature stage revealed that Slow release potassium K1 could enhance potassium adsorption of tobacco plants,increase the plant height,the length of internode and leaves,improve the resistance to weather fleck,wild fire disese,TMV and CMV,and enhance aroma quality,combustibility and ash color.The brassinolide used in fast growth period could decrease the wild fire disease index and content of chlorine in tobacco leaves,and improve the first grade leaf proportion,average price,yields and economic value.The irrigation in mature stage could decrease the content of chlorine,but tobacco diseases were more serious.
