白肋烟的产量和质量受自然气候、土壤、品种和栽培调制技术等因素的影响。不同播种移栽期的白肋烟,生长发育和成熟调制所处的气候条件不同,产量和质量也随之而异。为摸索白肋烟的最佳播种移栽期,给大面积示范和生产提供科学依据,1989～1990年连续两年在蒙自县进行了试验研究,现将主要结果报道如下。
The yield and quality of burley tobacco is affected by factors such as natural climate, soils, varieties and cultivation and modulation techniques. Different planting and transplanting of burley tobacco, growth and development of mature modulation in different climatic conditions, yield and quality also vary. In order to explore the best sowing and transplanting stage of burley tobacco, provide a scientific basis for large-scale demonstration and production, and carry out experimental research in Mengzi County from 1989 to 1990 for two consecutive years. The main results are reported as follows.
