不同垄作方式与覆膜厚度对烤烟根系生长发育的影响
|
摘要
以豫烟10号为试材,以传统起垄覆薄膜栽培为对照,研究不同起垄方式并覆膜厚度对烤烟根体积、根干重、根系活力及根系分布的影响。结果表明,中凹型起垄覆厚膜比传统起垄方式覆薄膜有助于增加烤烟生长前期的根体积及质量,促进烤烟不定根及近根位置须根的发生,增加须根及不定根的活力。综合分析认为,中凹型起垄方式并覆盖厚膜技术能有效改善烟株根系的生长发育状态,对烟株根系生长发育更为有利。
The experiment had been conducted to study the effects of different ridge culture modes and mulching film thickness on root growth and distribution of flue-cured tobacco.Yuyan 10 was used as material,and the conventional ridge forming method with thin film was used as the control.The results showed that the middle-concave ridge cultivation with thick film was superior to the conventional ridge cultivation in increasing the root volume and biomass,enhancing the appearance of adventitious roots and fibrous roots close to the taproot,and increasing the activity of adventitious roots and fibrous roots in the early growth period of tobacco.All the results suggested that the middle-concave ridge cultivation with thick film was more benefit to the growth and development of tobacco roots.
