Abstract
[Objective] To explore the optimal transplanting period of Honghuadajinyuan in low latitude and high altitude areas.[Method]Five different transplanting dates were designed in tobacco planting area of Xiyi Town,Mile City,Yunnan Province,which were.April 1,April 10,April 20,April 30 and May 5 (CK).Effects of different transplanting dates on the survival rate,agronomic trait,diseases and pests,economic characters were researched after transplanting of Honghuadajinyuan.[Result] In tobacco area of Mile City,transplanting treatment in April 1 could effectively avoid the infection outbreak of tobacco black shank,and reduced the incidence rate and disease index compared with conventional transplanting.Early growth and quick tillering of tobacco seedlings prolonged the growing stage in field,was helpful to the accumulation of dry matter and the maturity of tobacco leaves,and had relatively good performance in main economic indicators.[Conclusion] The proper transplanting date of Honghuadajinyuan was April 1 in Xiyi Town,Mile City and other planting areas with similar meteorological conditions.
