不同栽培措施对丰都烟区云烟116生长、产量和质量的影响
Effects of different cultivation practices on the growth,yield and quality of Yunyan 116 in Fengdu tobacco planting area
摘要
Abstract
In present study,nine treatments were set up according to L9(34),the planting densities were 15 750,16 650 and 17 250 plants·hm-2,the nitrogen application rates were 96.9,108 and 119.1 kg·hm-2,and the number of leaves remained were 15,17 and 19 for studying the supporting cultivation measures of flue-cured tobacco variety Yunyan 116 in Fengdu tobacco area of Chongqing.The results showed that with the increase of planting density,the leaf area co-efficient and tobacco aroma content increased,but the plant height,potassium chloride ratio and sensory evaluation quali-ty decreased.With the increase of nitrogen application rate,the plant height,yield and output value increased,but the potassium content,potassium chloride ratio and sensory evaluation quality of cured tobacco decreased.With the increase of the number of leaves remained,the leaf area coefficient increased,the potassium chloride ratio of cured tobacco,the quality of sensory evaluation and the proportion of premiumtobacco decreased,and the plant height first increased and then decreased.Among the three factors,the planting density had a great influence on the output value,while nitrogen appli-cation rate had a great influence on the plant height,output value,and sensory quality evaluation.The number of remaining leaves had a great influence on the leaf area coefficient,yield,the proportion of high-quality tobacco,the coordination of chemical components of flue-cured tobacco,and the total amount of aroma substances.Under the conditions of this study,when the planting density was 15 750 plants·hm-2,the nitrogen application rate was 108 kg·hm-2 and the number of remaining leaves was 17,Yunyan 116 had better plant height,leaf area coefficient,economic benefits and more harmoni-ous chemical composition,in Fengdu tobacco planting area of Chongqing.关键词
