稻茬烤烟上部烟叶一次性采收叶片数研究
Study on the Number of Upper Leaves Harvested at One Time in Paddy-Tobacco of the Yunyan 87 Variety Based on Three Harvests
摘要
Abstract
To determine the optimal number of upper leaves to harvest in each of three harvests from paddy-tobacco,Yunyan 87 was used as the test material,and three treatments(5,6,and 7 leaves per harvest)were designed.The effects of different harvested leaf numbers on economic traits and quality were investigated.The results showed that as the number of leaves harvested increased,single-leaf weight,leaf thickness,starch content,and chlorogenic acid content decreased,while the proportion of sound leaves decreased and the proportion of variegated and greenish leaves increased.Harvesting 5 leaves resulted in 6.2 and 7.1 percentage points higher rates of superior leaves compared with harvesting 6 and 7 leaves,respectively;yield increased by 1.0％and 7.2％,and output value by 1.5％and 9.7％,respectively;smoking quality scores were 2.3％and 3.1％higher,respectively.Based on the comprehensive evaluation of quality and economic indicators,harvesting 5-6 upper leaves per harvest is recommended for paddy-tobacco under the three-harvest regime.关键词
