摘 要:為實現(xiàn)烤煙廢棄鮮葉的最大化利用,研究了以廢棄鮮葉發(fā)酵產(chǎn)物——沼渣作有機肥對烤煙農(nóng)藝性狀、抗病性、煙葉產(chǎn)質(zhì)量的影響。結(jié)果表明:施用沼渣對烤煙田間主要病害無誘發(fā)作用,也不影響烤煙產(chǎn)量,但能明顯促進煙葉干物質(zhì)的積累,提高烤后煙葉經(jīng)濟性狀,改善烤后煙葉內(nèi)在化學成分含量比例,提升感官評吸質(zhì)量;在一定用量范圍內(nèi)隨著沼渣施用量的增加,烤煙田間農(nóng)藝性狀、經(jīng)濟性狀、內(nèi)在化學成分、評吸質(zhì)量等指標也隨之加強;尤其是沼渣施用量為150 kg/667m2的處理,各項指標均表現(xiàn)最優(yōu),產(chǎn)值比對照高383.8元/kg。
關鍵詞:烤煙;廢棄鮮葉;發(fā)酵;沼渣;產(chǎn)量;質(zhì)量

Abstract:In order to maximize the use of discarded tobacco fresh leaves, a test was carried out to studied the influence of biogas residue, fermentation product from discarded fresh leaf, on the agronomic trait, disease-resistance and the yield-quality of tobacco. The results showed that biogas residue application induced no main disease in the flue-cured tobacco field and had no effect on the yield. However, it significantly promoted the accumulation of tobacco dry matter, enhanced the economic characters of tobacco, improved the proportion of tobacco chemical component, and raise sensory-smoking quality. In addition , with the increasing the amount of biogas residue in a certain extent, the index such as the agronomic traits, economic characters, internal chemical component and the sensory-smoking quality were improved. And especially the application amount of 150 kg/667m2, all the index had good expression and there was 383.8 yuan per kilogram higher than contrast in output value.

烤煙廢棄鮮葉主要指烤煙生產(chǎn)過程中產(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。烤煙廢棄鮮葉再利用率低[1],且含有大量的生物堿(其中92%~95%為煙堿)[2],降解比較困難,處理不當容易造成病害傳播和環(huán)境污染。為探索烤煙廢棄鮮葉的循環(huán)利用新途徑,吉安市煙草公司開展了以烤煙廢棄鮮葉作為沼氣發(fā)酵原料的相關研究,結(jié)果表明,烤煙廢棄鮮葉可以作為沼氣發(fā)酵原料生產(chǎn)沼氣,在自然條件下,產(chǎn)氣周期在170 d以上、原料產(chǎn)氣效率在0.3 m3/kg以上[3]。另有研究表明,沼肥(沼氣池厭氧發(fā)酵的產(chǎn)物)可以在烤煙生產(chǎn)上應用[4],施用適量的沼肥可促進煙株生長發(fā)育、提高煙葉產(chǎn)量和品質(zhì)[5-6]。為實現(xiàn)烤煙廢棄鮮葉的最大化利用,吉安市煙草公司進一步開展了利用廢棄鮮葉發(fā)酵沼渣作有機肥對烤煙農(nóng)藝性狀、抗病性、煙葉產(chǎn)質(zhì)量的影響,以期為廢棄鮮葉發(fā)酵沼渣在烤煙生產(chǎn)上的應用提供依據(jù)。
