摘要
为有效防治烟草青枯病、提高烟叶品质,采用田间试验,研究了单施土壤调理剂(T2)、单施含有烟草青枯病拮抗菌的生物有机肥(T3)、土壤调理剂与生物有机肥混合施用(T4)对烤烟农艺性状、烤烟病害发生及烤烟产、质量的影响。结果表明,与当地常规施肥(CK,T1)相比,T2、T3、T4处理烤烟产值分别增加9.1%、8.9%、7.6%,上等烟比例分别提高了2.6%、3.4%和3.6%;T3和T4处理的烟株青枯病、花叶病病情指数分别较T1处理降低22.8%和26.3%、56.9%和35.0%。通过施用土壤调理剂调节土壤酸碱性和利用生物有机肥提高土壤微生物活性,可有效促进烟株的生长发育,提高烟株的抗病性和烤后烟叶品质。
In order to prevent tobacco bacterial wilt and improve tobacco quality,a field experiment was conducted to study the application effects of soil conditioner （T2 ）,bio-organic fertilizer（T3）,and mixture of soil conditioner and bio-organic fertilizer（T4）on disease occurrence and tobacco quality.The results showed that,comparing with local conventional fertilization（CK, T1）,the output value of T2,T3 and T4 increased by 9.1%,8.9%,7.6%,respectively,and the high grade tobacco increased by 2.6%,3.4% and 3.6%,respectively.The bacterial wilt and mosaic disease indexes of T3 decreased by 22.8% and 56.9%,and those of T4 decreased by 26.3% and 35.0%,respectively.Therefore,application of soil conditioners and bio-organic fertilizer to adjust the soil pH and improve the soil microbial activity could promote the growth and development of tobacco plant.As a result,it would improve the tobacco plant disease resistance,yield and quality of flue-cured tobacco.
