| Variety is the foundation for the development of the tobacco leaves,it is also an important factor in the evaluation of tobacco quality.The world’s leading tobacco generals pay great attention to the breeding of new varieties.Fuchuan tobacco growing area is important smoke zone in Guangxi,all the year pianting tobacco around 4000 hm~2.In recent years,with the perennial planting and variety of the main cultivar Yunyan 87,the characteristics of the varieties have been degraded year by year,and the pests and diseases have been seriously affected,and the tobacco is affected by the tobacco industry.The quality and yield.Therefore,in order to reduce the occurrence of pests and diseases and to stabilize the development of tobacco,this paper studies the production adaptability of Yueyan 97;in Fuchuan by selecting,introducing,comparing and demonstrating the experiment.The results showed as follows:1.In 2012 more field test results show that Yueyan 97 field growth period,128d,plant type was the tower of Yueyan 97 plant height was significantly higher than that of Yunyan 87,Yueyan 97 color,maturity,leaf structure,oil and other aspects with Yunyan 87 had no significant difference,the appearance of good quality.Resistance to weather fleck significantly,yield and output value were significantly higher than that of Yunyan 87,Yunyan 87 respectively increased by 14.2%and 14.97%,the proportion of superior tobacco are basically the same,Yueyan 97 and Yunyan 87 in the nicotine content in different parts of the difference reached significant level,Luzhou style is more obvious.In 2013 the pilot test results showed that Yueyan 97 in Fuchuan tobacco area production adaptability and good stability,the indicators have reached or exceeded 87 in Yunyan botany shape,agronomic traits,disease resistance,economic benefit,appearance quality,chemical composition and sensory quality,Yueyan 97 in topping height,yield per mu the content of nicotine and lower output value were significantly higher than that of Yunyan 87,anti climate spot disease significantly,strong industrial availability.2.2014Fuchuan three major producing areas of large area demonstration shows that the economic value of Yueyan 97;and industrial value higher than Yunyan 87,has a good promotion value. |
