Abstract
[ Objective ] This study aimed to demonstrate the effects of retained leaf number and removed bottom leaf number on KRK226 yield and quality. [ Method ] Based on multi-factor split-plot design, botanical and agriculture characters,resistance to disease ,appearance quality,curing and economic characters of KRK26 were studied. [ Result ] With increased retained leaf number, growth period prolonged and plant height and pitch increased,however,the plant girth and leaf aera showed a decreasing trend. An increase in retained leaf number led to a decrease in Alternaria alternate. The maturity,color,glossiness,oil and leaf structure of raw tobacco were umelated to retained leaf number,but yield,output per mu and first-class leaf proportion decreased with removed bottom leaf number. Besides, mottle leaf proportion to the whole leaf decreased with increased retained leaf number,and retained 20 leaves and removed 4 bottom leves were optimal in saffron and medium-class leaves proportion. [ Conclusion]The optimum yield and quality requirement for KRK26 were 22 retained leaves and 4 removed bottom leaves.关键词
