【摘要】：為有效防治煙草青枯病、提高煙葉品質(zhì),采用田間試驗,研究了單施土壤調(diào)理劑(T2)、單施含有煙草青枯病拮抗菌的生物有機肥(T3)、土壤調(diào)理劑與生物有機肥混合施用(T4)對烤煙農(nóng)藝性狀、烤煙病害發(fā)生及烤煙產(chǎn)、質(zhì)量的影響。結(jié)果表明,與當?shù)爻Ｒ?guī)施肥(CK,T1)相比,T2、T3、T4處理烤煙產(chǎn)值分別增加9.1%、8.9%、7.6%,上等煙比例分別提高了2.6%、3.4%和3.6%;T3和T4處理的煙株青枯病、花葉病病情指數(shù)分別較T1處理降低22.8%和26.3%、56.9%和35.0%。通過施用土壤調(diào)理劑調(diào)節(jié)土壤酸堿性和利用生物有機肥提高土壤微生物活性,可有效促進煙株的生長發(fā)育,提高煙株的抗病性和烤后煙葉品質(zhì)。
[Abstract]:In order to effectively control tobacco bacterial wilt and improve tobacco leaf quality, a field experiment was conducted to study the application of soil conditioner (T2) and biological organic fertilizer (T3) containing antagonistic bacteria against tobacco bacterial wilt. Effects of mixed Application of soil Conditioner and Bio-organic Fertilizer (T4) on Agronomic characters of Flue-cured Tobacco, occurrence of Flue-cured Tobacco Disease, yield and quality of Flue-cured Tobacco. The results showed that compared with local conventional fertilization (CK,T1), the output value of flue-cured tobacco treated with T2N T3N T4 increased by 9.1% and 8.9%, and the proportion of superior tobacco increased by 2.6% and 3.6%, respectively. The disease index of tobacco plants treated with T3 and T4 was 22. 8% and 26. 3% and 35. 0% lower than that of T1, respectively. Applying soil conditioner to regulate soil acidity and alkalinity and using biological organic fertilizer to improve soil microbial activity can effectively promote the growth and development of tobacco plants and improve the disease resistance of tobacco plants and the quality of cured tobacco leaves.
