摘要: 为研究K326在大理烟区适宜的打顶措施,开展裂区试验对比初花打顶、盛花打顶情况下分别留叶18、20、22片对K326产量和质量的影响。结果表明:初花打顶处理在农艺性状、经济性状、内在化学品质3个方面整体优于盛花打顶处理。初花打顶处理且留22片叶处理烤烟长势最好,产量最高,但产值、均价、中等烟比例、上等烟比例与内在化学成分稍逊;初花打顶处理且留20片叶在各处理中烟叶经济效益较高,内在化学成分最为协调。综合各项指标,大理烟区种植K326初花打顶处理且留20片叶最为适宜。

关键词: 烤烟, 打顶时间, 留叶数, 产量和质量

Abstract:

To determine the suitable topping measures for K326 in Dali tobacco-growing areas, a split-plot experiment was conducted to compare the effects of topping at early flowering and full flowering stages with 18, 20, and 22 leaves retained on the yield and quality of K326. The results showed that topping at the early flowering stage generally outperformed topping at the full flowering stage in terms of agronomic traits, economic traits, and internal chemical quality. Topping at the early flowering stage with 22 leaves retained resulted in the best growth and highest yield of flue-cured tobacco, but the output value, average price, proportion of medium-grade tobacco, proportion of high-grade tobacco, and internal chemical composition were slightly inferior. Topping at the early flowering stage with 20 leaves retained achieved higher economic benefits and the most balanced internal chemical composition among all treatments. Based on comprehensive evaluation of various indicators, topping at the early flowering stage with 20 leaves retained is the most suitable practice for cultivating K326 in Dali tobacco-growing areas.

Key words: flue-cured tobacco, topping time, number of leaves retained, yield and quality
