摘要
Abstract
Taking flue-cured tobacco variety(Yunyan 85)as materials,the effects of three different film uncovering times(30 d,40 d and 50 d)and total growing stage film mulched on the growth,internal chemical properties,physical properties,yields and production value of flue-cured tobacco were studied. Results showed that the yields and quality of different film uncovering times was significant compared with film mulched treatment,the contents of total Nitrogen(N),potassium(K)and chlorine(Cl)showed the tendency of increase with more harmonious of internal chemical component in film uncovering times(40 d and 50 d). The average price,yields and production value increased in different extent,with 40 d as the optimum film uncovering time.关键词
