          摘 要:為探索廢棄鮮煙葉發(fā)酵后沼液的再利用方式,開展了沼液不同葉面噴施方法對(duì)烤煙生長(zhǎng)發(fā)育的影響的試驗(yàn)。試驗(yàn)分別對(duì)比了在烤煙團(tuán)棵、旺長(zhǎng)、打頂后不同時(shí)期噴施沼液的5個(gè)處理組的數(shù)據(jù),結(jié)果表明:廢棄鮮煙葉發(fā)酵沼液對(duì)烤煙主要田間病害無(wú)誘發(fā)或傳播作用;噴施沼液對(duì)中上部葉片發(fā)育和干物質(zhì)積累有促進(jìn)作用,與不噴施沼液相比,烤煙產(chǎn)量、上等煙比例、均價(jià)有所提高,中上部煙葉外觀質(zhì)量有所改善;以旺長(zhǎng)期噴施效果最好,其次是團(tuán)棵期,打頂后噴施效果不如前兩個(gè)時(shí)期明顯,不同時(shí)期多次噴施對(duì)相關(guān)性狀的改善有正向作用。

          Abstract:In order to explore re-use of biogas slurry from fermentation of fresh flue cured tobacco leaves, this paper studied the influence of  biogas slurry spraying methods on growth and development of flue-cured tobacco. Test were compared in the rosette stage, faster growing stage, topping in different period after spraying biogas slurry of five treatment groups of data, the results showed that: the fresh leaf of flue-cured tobacco waste biogas slurry did not induce or propagate tobacco field disease; spraying biogas slurry could promote development of upper leaves and increase dry matter accumulation. Compared to CK, tobacco yield, superior tobacco proportion and average price, and middle and upper leaves appearance quality were improved by spraying. Spraying in faster growing stage has the best effect, followed by that in rosette stage, then after multi-topping, repeatedly spraying on the related traits in different periods had positive effect.

          廢棄鮮煙葉主要指烤煙生產(chǎn)過(guò)程中產(chǎn)生的奶腳葉和需要田間處理掉的發(fā)育不良、結(jié)構(gòu)僵硬、工業(yè)可用性低的鮮煙葉。廢棄鮮煙葉再利用率低[1],且含有大量的生物堿(其中92%~95%為煙堿)[2],降解比較困難,處理不當(dāng)容易傳播病害和污染環(huán)境。為探索廢棄鮮煙葉的循環(huán)利用新途徑,吉安市煙草公司開展了烤煙廢棄鮮葉循環(huán)利用的相關(guān)研究,前期結(jié)果表明廢棄鮮煙葉可以作為沼氣發(fā)酵原料正常生產(chǎn)沼氣[3],發(fā)酵后的沼渣作為烤煙肥料對(duì)其產(chǎn)質(zhì)量提高有促進(jìn)作用[4]。前人研究表明,普通沼液可以應(yīng)用于蔬菜、果樹、煙葉等農(nóng)作物[5-7],沼液葉面噴施對(duì)玉米、脫水油白菜、番茄等作物田間生長(zhǎng)發(fā)育性狀的改善有一定作用[8-10]。為實(shí)現(xiàn)廢棄鮮煙葉的最大化綜合利用,吉安市煙草公司進(jìn)一步開展了田間廢棄鮮煙葉發(fā)酵沼液不同葉面噴施方法對(duì)烤煙生長(zhǎng)發(fā)育影響的研究,以期為其在烤煙生產(chǎn)上的應(yīng)用提供理論依據(jù),并形成完整的烤煙田間廢棄鮮葉循環(huán)利用標(biāo)準(zhǔn)體系。
          1 材料與方法
          1.1 試驗(yàn)材料
          試驗(yàn)于2014年3月至2014年7月在江西省安福縣現(xiàn)代煙草農(nóng)業(yè)科技園進(jìn)行,供試煙田為水田,土壤質(zhì)地為砂泥田,近兩年未做過(guò)相關(guān)肥料試驗(yàn)。
          供試烤煙品種為K326,3月10日移栽,行距110 cm,株距55 cm。
