箭舌豌豆不同翻压期对金神农烤烟产量和品质的影响

摘要

为提高箭舌豌豆翻压改良烟田土壤效果,在湖北十堰烟区,采用田间试验,研究了箭舌豌豆不同翻压期对金神农烤烟生长、产量和品质的影响,结果表明:在减少化肥施用量15%、绿肥翻压22500 kg/hm2情况下,于烤烟移栽前30 d翻压效果较好,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处理.%In order to increase the improving effect of Vicia sativa application as green manure on the soil of tobacco field, the author studied the effects of V.sativa application date on the growth, yield and quality of Jinshennong flue-cured tobacco through field experiments in Shiyan city, Hubei province.The results showed that: under the conditions of reducing chemical fertilizer application rate by 15%, and turning 22500 kg/hm2 green manure (V.sativa) over, applying V.sativa on the 30th day before transplanting flue-cured tobacco had better improving effects, and the agronomic characters (plant height, maximum leaf area, and so on), the dry matter biomass of root, stem, leaf and whole plant, and the leaf yield and output value of flue-cured tobacco were close to or higher than those in the treatment of conventional fertilization.
