摘要
为明确不同株距对烟苗生长发育的影响,以烤烟K326为试验材料,研究了试验托盘根际空间一致(90 cm^3)的条件下,不同株距(3、6、9 cm)处理对烤烟苗期根、茎、叶发育和相关生理指标的影响。结果表明,不同株距对烟苗群体结构、新生叶发生速度、叶片数量、各部位叶面积、光合特性、茎高、节距、茎半径、茎木质化程度、根系构型和根系活力均有显著影响,但烟苗株型和伸长量最大的节位不随株距变化而改变。不同株距影响了烟苗群体结构、表型和相关生理指标,根际空间90 cm^3、株距6 cm更有助于烟苗的生长发育。
In order to study the effects of different planting spaces on growth and development of tobacco seedlings,flue-cured tobacco K326 was used as experimental material to research the root,stem,leaf development and correlative physiological index under treatments with same rhizosphere space(90 cm^3)and different planting spaces(3,6,9 cm).The results showed that,different planting spaces could significantly influence the colony structure,emergence speed of new leaf,leaf number,leaf area,photosynthetic characters,stem height,stem radius of each node,stem pitch,lignified degree of stem,root architecture and root activity of seedings.The plant-type and the maximum elongation node were constant among different treatments.It was concluded that,different planting spaces could affect the colony structure,phenotype and physiological index of tobacco seedlings.The rhizosphere space of 90 cm^3 and the planting space of 6 cm were beneficial to seedlings growth and development.
