作者王依纯,廉华,马光恕,李梅,高长敏,台莲梅,曲虹云(2019)在《木霉不同施用方式对黄瓜幼苗质量特性及枯萎病防效的影响》一文中研究指出:黄瓜枯萎病是设施黄瓜栽培中最为常见且为害严重的土传真菌病害,应用生防菌防治黄瓜枯萎病,对黄瓜安全生产有重要意义。试验采用前期筛选的对黄瓜枯萎病菌有较好拮抗效果的3株木霉菌,即棘孢木霉Trichoderma asperellum 525、哈茨木霉T. harzianum 610和拟康氏木霉T. pseudokoningii 886,利用盆栽试验,测定了木霉菌不同施用方式对黄瓜幼苗质量及枯萎病防效的影响。3种施用方式分别为T1(木霉与病原菌同时接种)、T2(先接种木霉菌,2d后接种病原菌)和T3(先接种病原菌,2d后接种木霉)。结果显示,3株木霉菌对黄瓜枯萎病的防效均在64.78%以上,且以拟康氏木霉886的T2施用方式的防效最高,达到81.54%。在播种后8~14 d,所有木霉菌处理的黄瓜幼苗壮苗指数、叶绿素含量、根系活力、硝态氮含量、硝酸还原酶活性、根系总吸收面积均比CK1(只接种病原菌孢子悬液)显著上升,3种施用方式中以T2处理对上述6项指标的促进效果最显著,并以拟康氏木霉886在播种后14 d的6项指标增加幅度最大,该处理的黄瓜壮苗指数、叶绿素含量、根系活力、硝态氮含量、硝酸还原酶活性、根系总吸收面积的增加幅度分别达到210.06%、74.39%、37.23%、54.45%、88.00%和51.11%。本研究的3株木霉菌通过提高黄瓜幼苗生理代谢活性,增强了幼苗质量,提高了对黄瓜枯萎病的抗性,在应用中,提前施入木霉菌,有利于提高黄瓜幼苗对病害的防治效果,为后期提高黄瓜产量和品质奠定基础条件。
