摘　　要：为了合理利用绿肥轮作改良烟田土壤、提高烤烟产质,在湖北恩施烟区采用田间试验研究了烤烟复种光叶紫花苕子作绿肥时不同翻压期对烤烟生长、产量和品质的影响。连续2年的定位试验表明,在减少化肥施用量15%、翻压绿肥15000kg/hm2情况下,于烤烟移栽前15～25天翻压绿肥效果较好,烤烟株高、最大叶面积等农艺性状,根、茎、叶及整株干物质量,烟叶产量和产值接近于或高于常规施肥措施,但是移栽前35天翻压等量光叶紫花苕子作绿肥,烤烟生长明显较差,产量和产值显著降低。减少化肥用量15%基础上不同时期翻压绿肥,有利于烤烟上部叶发育,使其单叶重量增加4.5%～18.5%,还可使中上等烟比例提高2.7～8.6个百分点。In order to improve soil,yield and quality of flue-cured tobacco,the effects of different application times of green manure in Vicia villosa var.glabresens-tobacco rotation were studied under the condition of field experiments in Enshi,Hubei Province.The results from 2 years ＇ experiments showed green manuring in 15-25 days earlier than tobacco transplantation was appropriate when chemical fertilizer amount was 85% of the conventional dose and green manure application rate was 15000 kg/hm 2.In this case,some agronomic traits like plant height and largest leaf area,dry matter weight of root,stem,leaves and whole plant,yield and production value of flue-cured tobacco were higher than or similar to the conventional technique of fertilization.When green manure was applied in 35 days earlier than tobacco transplantation,the tobacco could not grow well,its yield and production value were significantly decreased.Compared with conventional technique of fertilization,the upper leaves of tobacco grew better,its dry matter weight was increased by 4.5%-18.5%,the proportion of high and middle grad tobacco was improved by 2.7%-8.6%,when conventional chemical fertilizer rate was reduced by 15% and 15000 kg/hm 2 of green manure was applied in 15-35 days ahead of tobacco transplantation.
