摘要 為充分發(fā)揮湘煙7號的生產(chǎn)潛力，優(yōu)化配套生產(chǎn)技術(shù)，采用裂區(qū)設(shè)計(jì)，研究了9種不同的田間結(jié)構(gòu)對湘煙7號產(chǎn)質(zhì)量的影響。結(jié)果顯示，打頂時(shí)留葉21片、下部葉優(yōu)化 4片和打頂時(shí)留葉22片、下部葉優(yōu)化 5片，這2種田間結(jié)構(gòu)最有利于湘煙7號獲得較高的煙葉產(chǎn)量和較好的煙葉質(zhì)量。

Abstract To give full play to the production potential of Xiangyan 7 and to optimize the supporting planting technology， the effects of 9 different field structures on the yield and quality of Xiangyan 7 were studied by split plot design.The research results showed that the two field structures were 21 leaves left after topping and 4 leaves removed at the bottom， and 22 leaves left after topping and 5 leaves removed at the bottom.These two field structures were most favorable for Xiangyan 7 to obtain higher yield and better quality of tobacco leaves.
