前言烤烟种子生产和烟叶生产的目的不同,二者既矛盾又统一。前者是以获得量多质优的种子为目的,后者则以获得优质和一定生产水平的烟叶为目的。由于栽培的目的不同,采取的措施也不尽相同。在留种的条件下,烟叶生产和种子生产的关系如何,烤烟种子生产需要什么样的条件和措施等,都是种子繁育技术应当研究的问题。为此,我们进行了烤烟留种田种子生产与烟叶生产关系的研究,对种子生产和 Preface The purpose of flue-cured tobacco seed production and tobacco production is different, both contradictory and unified. The former aims at obtaining seeds of high quality and quantity while the latter aims at obtaining tobacco with good quality and certain production levels. Due to the different purposes of cultivation, the measures taken are not the same. Under the conditions of remaining seeds, the relationship between tobacco production and seed production, what kind of conditions and measures are needed for the production of flue-cured tobacco seeds are all issues that should be studied in seed breeding technology. To this end, we conducted a study on the relationship between seed production and tobacco production in flue-cured tobacco farming,
