摘要
研究不同机耕深度和起垄高度对烤烟生育期、农艺性状、化学成分和经济效益的影响。结果表明,随着机耕深度和起垄高度的增加,烟株在团棵期以后的生育期推迟。机耕深度的增加有利于烟株长高,起垄高度的增加能弥补机耕深度对烟株株高的影响。机耕深度在11~13 cm、起垄高度在33~36 cm时有利于烟株叶片数增加和烟株中上部叶开片;机耕深度13 cm、起垄高度33~36 cm时,各部位化学成分协调;当机耕深度达13 cm、起垄高度达36 cm时,烟叶产量和效益最好。
Effects of different mechanical depth and ridge height on the growth period,agronomic characters,chemical component and economic benefits of flue-cured tobacco were studied.The results showed that the growth period of tobacco plants was delayed after the cluster stage with the increase of mechanical depth and ridge height.The increase of mechanical depth was beneficial to the height of tobacco plants.The increase of ridge height could make up for the influence of the mechanical depth on the height of tobacco plants.It was beneficial to the increase of leaf number and the opening of cutter and upper leaves when the mechanical depth was 11 to 13 cm and the ridge height was 33 cm to 36 cm.The chemical component of cured leaves in different positions was coordinated when the mechanical depth was 13 cm and the ridge height was 33 cm to 36 cm.It was beneficial to the stout stem of tobacco plants and the best economic benefit of tobacco when the mechanical depth was about 13 cm and the ridge height was 36 cm.
