不同海拔高度对香料烟沙姆逊生长发育及品质的影响
Effects of Altitude on Growth,Development and Quality of Oriental Tobacco Samson
摘要
Abstract
In order to explore the effects of different altitudes on growth,development and quality of ori-ental tobacco in Baoshan,Yunnan,the differences of agronomic traits,dry matter mass,physical properties,chemical compositions and economic traits of oriental tobacco Samson at different altitudes of 700,1 100 and 1 500 m were studied.The results showed that with the increase of altitude,the agronomic traits,physical characteristics,chemical compositions,chlorophyll content,leaf area index and economic traits showed the trend of increasing first and then decreasing.Grey correlation analysis showed that altitude had the greatest im-pact on dry matter mass,followed by economic traits.Compared with 700 m and 1 500 m,the total dry weight at 1100 m significantly increased by 57.16%and 13.46%respectively,and the yield and output value signifi-canty increased by 28.13%,38.52%and 15.89%,16.79%respectively.The result of principal component a-nalysis showed that the contribution rates of the two principal components were 86.10%and 6.10%,respec-tively,and the cumulative contribution rate was 92.20%.The total score of the three altitudes showed the high-est at 1 100 m,followed by that at 1 500 m,and that at 700 m was the lowest.In conclusion,under the con-ditions of this study,the Samson variety had better growth and development at the altitude of 1100 m with rel-atively coordinated chemical compositions,better quality and economic traits,and high availability of tobacco leaves,so it was suitable for planting at the altitude of 1 100 m.关键词
