120cm行距下不同株距和留叶数对硃砂烟农艺性状及产质量的影响
Effects of Different Plant Spacings and Remained Leaf Numbers on Agronomic Traits,Yield and Quality of Cinnabar Tobacco under 120-cm Row Spacing
摘要
Abstract
This experiment was carried out by two-factor design with different plant spacings(50,55 and 60 cm)under 120-cm row spacing and remained leaf numbers(18,20 and 22)as the two factors.A to-tal of 9 treatments were set to study their effects on growth period,agronomic traits,disease incidence,photo-synthetic characteristics,economic traits and chemical components of flue-cured tobacco leaves.The results showed that with the increase of planting density and remained leaf number,the growth stages of tobacco plants prolonged,and the disease incidence increased significantly.The net photosynthetic rate of leaves,yield,average price,output value and proportion of middle and superior tobacco leaves decreased with the in-crease of remained leaf number at 50 cm of plant spacing,and increased first and then decreased at 55 cm of plant spacing,and significantly increased at 60 cm of plant spacing.There were significant differences in the content of chemical components of flue-cured tobacco leaves,but all of them were in the suitable range of high-quality flue-cured tobacco.On the whole,the yield of cinnabar tobacco was higher and the quality was better when the number of leaves remained was 18 at 50 cm of plant spacing,20 at 55 cm of plant spacing,and 22 at 60 cm of plant spacing.关键词
