摘要
为研究不同移栽期对烤烟各时期生长发育的影响,确定延安地区烤烟膜下移栽的最佳移栽期。采用当地主栽品种秦烟96,设4个移栽期(T1:4月18日;T2:4月24日;T3:4月30日;T4:5月6日)分析不同移栽期对烟草各生育期的农艺性状和最终经济性状等影响,最后确定该地区的最佳移栽期。结果表明:4月24日至4月30日移栽对烤烟生长最为有利;烤烟生长势的变化趋势和叶片生长变化表明,前期T1处理生长势最大,T4最弱,但随着生育期的推进,T1的生长势逐渐减缓,而T2、T3和T4处理生长势逐渐增强;不同移栽期烟草经济效益表现为T3>T2>T4>T1。说明,移栽期为4月30日的烤烟农艺学性状和经济性状要好于其他移栽期,故延安地区烤烟膜下移栽期以4月30日为宜。
In order to study the impact of different transplanting periods on the growth and develop- ment of the flue-cured tobacco in each growing period and determine the best transplanting period in Yan＇an region for flue-cured tobacco that under films. In this study, the local cultivars Qin smoke 96 was used and a total of four different transplanting stage were condulted, TI： April 18, 2011; T2： April 24, 2011; T3. April 30, 2011 and the T4： May 6, 2011. Agronomic traits and the ultimate economic traits were measured and analyzed, in different experiments and finally the best transplanting period was determined. The results show that the trend growth potential from the flue-cured tobacco leaf growth changes may have come from the data analysis of plant height, number of leaves, stem girth, pitch transplanting on growth from April 24 to April 30 is the most favorable; out in the early, T1 handle growth potential, T4 weakest, but with the propulsion of the growth period, the growth potential of T1 has been slowing, T2, T3 and T4 treatment growth potential gradually increased; the economic benefits is T3 〉 T2〉T4〉 T1. The transplanting period at April 30 was better than other transplanting period and achieved a better agronomy traits and economic traits,so the favorable trans- planting period for tobacco under film in Yan＇an area is April 30.
