不同起垄高度对烟草生长发育的影响
|
摘要
为了探究有利于烤烟生长发育的起垄高度,在景东县进行了5个不同起垄高度对烟草生长发育影响的试验。结果表明:在团棵期,起垄高度为0和10 cm的烟株农艺性状比40 cm的好;旺长期起垄高度0 cm的烤烟农艺性状有所下降,而起垄高度10和20 cm的烤烟的农艺性状开始上升;成熟期起垄高度40 cm烤烟的农艺性状最好,而起垄高度0和10 cm的烤烟农艺性状较差;且起垄高度40 cm的烤烟黑胫病、根黑腐病、赤星病、炭疽病和白粉病的发病率最低。因此,建议在该地区推行起垄高度40 cm的栽植方式栽植烤烟。
In order to explore the ridging height which is more conducive to the growth and development of Flue-cured tobacco, five experiments were conducted in Jingdong County on the effects of ridging height on the growth and development of tobacco. The results showed that the agronomic traits of tobacco plants with ridging height of 0 and 10 cm were better than those of tobacco plants with ridging height of 40 cm. The agronomic traits of flue-cured tobacco with ridging height of 0 cm decreased in fast-growing stage, while those of flue-cured tobacco with ridging height of 10 cm and 20 cm began to increase. The agronomic traits of flue-cured tobacco with 40 cm ridging height at maturity stage grew best than those of other heights, while those of flue-cured tobacco with 0 and 10 cm ridging height were lower than those of other ridging heights. The incidence of diseases of black tibia, black rot, brown spot, anthrax, powdery mildew was the lowest among 40 cm ridging height of flue-cured tobacco. Therefore, it is suggested that flue-cured tobacco be planted in this area with a ridging height of 40 cm.
