Studies on Plant Type Characteristics of Flue-cured Tobacco K326 in Guizhou
摘要
Abstract
s:In order to understand the plant type characteristics of flue-cured tobacco K326 in Guizhou, a field experiment with two factors (plant density and number of leaves remained) was carried out to investigate the effects of different cultivation technique on plant type. The results showed that tobacco plants with 14 leaves remained were piping-piping type from 75 to 90 days after transplanting, with the largest leaf area on top leaf, about 165 days of growth period, low value, poorly coordinated chemical composition, and low sensory quality. Tobacco plants with 20 leaves remained were high deck-piping type from 75 to 90 days after transplanting, with growth period of about 155 days, the highest value, the well coordinated chemical composition, and high sensory quality. Tobacco plants with 24 leaves remained were high deck-high deck from 75 to 90 days after transplanting, with growth period of about 155 days, good value, well coordinated chemical composition, and the highest sensory quality. For different transplanting density, chlorophyll indices, photosynthetic indices and canopy indices of tobacco plants, 55 cm×100 cm density was good, the economic value were high, the chemical composition was well coordinated, and the sensory quality was the best. Ideal plant type of K326 was high deck-piping type after topping in Guizhou, the yield and quality of flue-cured tobacco were good if density was 18 195 plants/ha and 20 of leaves were remained.关键词
