Effects of Different Transplanting Periods on Growth,Yield and Quality of Flue-cured Tobacco in Cambodia
摘要
Abstract
The aim of this investigation is to determine the best transplanting period of flue-cured tobacco in Cambodia.A field experiment with three different transplanting periods was conducted to determine the effects on growth and development, and yield and quality of'Yueyan 98'and'Yunyan 87'flue-cured tobacco in 2015-2016. The results showed that compared with the normal transplanting period, the two varieties that transplanted 10 days earlier had better performance in agronomical characteristics, for instance, the plant height,leaf number and leaf length increased by 4.5 cm,1 piece and 0.6-2.0 cm,respectively.The economical characteristics increased significantly,per hectare yield of tobacco leaves,output value,the average price per kilogram,the proportion of superior tobacco leaves increased by 117.0-121.5 kg,6682.5-6905.7 yuan,1.7-2.1 yuan, 4.5-12.5 percentage points, the differences reached a significant level. The appearance quality score increased by 0.5-1.5, the ratios of sugar to nicotine and nitrogen to nicotine were increased, and the overall coordination was improved. With the transplanting date being postponed for 10 days, the agronomical and economical characteristics, chemical components, appearance quality showed the opposite trend. Therefore, early December is the best transplanting period in Kompong Cham of Cambodia, 10 days in advance can facilitate the growth of tobacco plants and improve tobacco production and quality.关键词
