摘要:

为研究不同保水剂对干旱胁迫下雪茄烟叶矿质元素含量的影响,以‘德雪3号’雪茄烟为试材,采用盆栽试验研究了保水剂种类(SAP保水剂、沃特保水剂和自制保水剂)与用量(2、4 和6 g·株-1)对雪茄烟生长过程中矿质元素含量消长规律的影响。结果表明,干旱胁迫下施用3 种保水剂均能显著增加烟叶生长发育前期N、P、K含量,减缓后期N、P积累,有助于C/N代谢及时转化与烟叶适时落黄,且在各时期烟叶中K含量均高于对照;抑制烟叶中Ca含量,防止烟叶过厚粗糙从而影响烟叶品质;增进烟叶中Fe、Mn、B、Zn、Cu等微量元素含量。对烟叶中矿质元素含量进行相关分析,结果表明,N、K、Ca、Mg之间存在协同增效作用;而B与N、K、Ca、Mg之间及Cu、Mn与Ca、Mg间均存在一定的拮抗效应。自制保水剂和SAP保水剂的施用量为4 g·株-1、沃特保水剂的施用量为6 g·株-1时对协调雪茄烟叶大、中、微量元素之间的平衡效果最佳。

Abstract:

To study the effects of different water retention agents on the contents of mineral elements in cigar leaves under drought stress, ‘Dexue No. 3’ was as the test material, a pot experiment was conducted to study the response of the interactions between the types (SAP, Walter and homemade water retention agent) and amounts (2, 4 and 6 g·plant-1) of water retention agents. The dynamic change of mineral elements in leaves were determined during the process of cigar growth. The results showed that the application of the three water retention agents under drought stress significantly increased the contents of N, P and K in leaves at the early stage, and slowed down the accumulation of N and P at the later stage, which helped the timely transformation of C/N metabolism and the timely yellowing of tobacco leaves. And the application of the three water retention agents under drought stress effectively increased the K content of tobacco leaves, which the K contents were higher than CK. The application of the three water retention agents could suppress the Ca content in leaves, which could prevent the tobacco leaves from being too thick and rough due to the high Ca content and the poor availability of tobacco leaves. As the growth and development progressed, the application of the three water retention agents had a certain promotion effects on increasing contents of Fe, Mn, B, Zn and Cu in cigar tobacco. The correlation analysis indicated there were synergistic effects between N, K, Ca and Mg, while there were certain antagonistic effects between B and N, K, Ca, Mg, and between Cu, Mn and Ca, Mg. Comparing different treatments, the effects of harmonizing the balance between large, medium and micro elements in cigar leaves were better when SAP, Walter and homemade water retention agent were applied at a dosage of 4,6 and 4 g·plant-1, respectively.
