为了探索烤烟漂浮育苗的最佳增温方式,避免低温寡照等不利自然环境对培育壮苗的影响,以云97为材料,采用9种不同的增温技术,研究其对烤烟的出苗、生育期、农艺性状、生产成本等的影响。结果表明:与常规漂浮育苗技术相比,水体加热增温技术、火管加热苗棚空气增温技术的烟苗各项指标都比其他加热措施强;但综合考虑,认为双棚覆盖增温保湿技术和晾盘降湿增温技术在培育壮苗、育苗成本和环境适应性等方面优势较为明显,能较全面地满足泸州县独特的气候条件,有较强的技术优势和推广潜力。
In order to explore the best way to increase the temperature of flue-cured tobacco seedlings and to avoid the unfavorable impact of natural environment, such as low temperature and low light, on the cultivation of strong seedlings, 9 different temperature-increasing techniques were used to study the effects of cloud 97 on the emergence and growth of flue- , Agronomic traits, production costs and other effects. The results showed that compared with the conventional floating seedling raising technology, the indexes of tobacco seedling with water heating heating technology and fire tube heating seedling shelter air warming technology were all better than those with other heating measures. However, considering the double hatch cover warming warming Technology and drying plate dehumidification warming technology in cultivating strong seedlings, nursery costs and environmental adaptability more obvious advantages, can more fully meet the unique climatic conditions of Luzhou County, have strong technical advantages and promotion potential.
